[PMID: 38776142 PMCID: PMC11100505 DOI: 10.4244/eij-d-23-00605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Accepted: 12/20/2023] [Indexed: 05/24/2024]
Abstract
BACKGROUND Coronary calcification negatively impacts optimal stenting. Intravascular lithotripsy (IVL) is a new calcium modification technique. AIMS We aimed to assess the impact of different calcium morphologies on IVL efficacy. METHODS This was a prospective, multicentre study (13 tertiary referral centres). Optical coherence tomography (OCT) was performed before and after IVL, and after stenting. OCT-defined calcium morphologies were concentric (mean calcium arc >180°) and eccentric (mean calcium arc ≤180°). The primary outcomes were angiographic success (residual stenosis <20%) and the presence of fracture by OCT in concentric versus eccentric lesions. RESULTS Ninety patients were included with a total of 95 lesions: 47 concentric and 48 eccentric. The median number of pulses was 60 (p=1.00). Following IVL, the presence of fracture was not statistically different between groups (79.0% vs 66.0% for concentric vs eccentric; p=0.165). The number of fractures/lesion (4.2±4.4 vs 2.3±2.8; p=0.018) and ≥3 fractures/lesion (57.1% vs 34.0%; p=0.029) were more common in concentric lesions. Angiographic success was numerically but not statistically higher in the concentric group (87.0% vs 76.6%; p=0.196). By OCT, no differences were noted in final minimum lumen area (5.9±2.2 mm2 vs 6.2±2.1 mm2; p=0.570), minimum stent area (5.9±2.2 mm² vs 6.25±2.4 mm2; p=0.483), minimum stent expansion (80.9±16.7% vs 78.2±19.8%), or stent expansion at the maximum calcium site (100.6±24.2% vs 95.8±27.3%) (p>0.05 for all comparisons of concentric vs eccentric, respectively). Calcified nodules were found in 29.5% of lesions; these were predominantly non-eruptive (57%). At the nodule site, dissection was more common than fracture with stent expansion of 103.6±27.2%. CONCLUSIONS In this prospective, multicentre study, the effectiveness of IVL followed by stenting was not significantly affected by coronary calcium morphology.

Drug-Eluting Balloons in Calcified Coronary Lesions: A Meta-Analysis of Clinical and Angiographic Outcomes. J Clin Med 2024; 13:2779. [PMID: 38792321 PMCID: PMC11122257 DOI: 10.3390/jcm13102779] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2024] [Revised: 04/16/2024] [Accepted: 05/06/2024] [Indexed: 05/26/2024] Open
Abstract
Background: The usefulness of drug-eluting balloons (DEBs) has not been fully elucidated in calcified coronary lesions (CCLs). This meta-analysis aimed to evaluate the efficacy of DEBs compared to a drug-eluting stent (DES) in this setting. Methods: PubMed, EMBASE and Cochrane were searched through December 2023. The primary endpoint was 12 months major adverse cardiac events (MACE). Secondary endpoints included clinical outcomes and angiographic results after PCI and at a 12-month follow-up. Results: Five studies and a total of 1141 patients with 1176 coronary lesions were included. Overall, the DEB was comparable to DES in MACE (RR = 0.86, 95% CI: 0.62-1.19, p = 0.36), cardiac death (RR = 0.59, 95% CI: 0.23-1.53, p = 0.28), myocardial infarction (RR = 0.89, 95% CI: 0.25-3.24, p = 0.87) and target lesion revascularization (RR = 1.1, 95% CI: 0.68-1.77, p = 0.70). Although the DEB was associated with worse acute angiographic outcomes (acute gain; MD = -0.65, 95% CI: -0.73, -0.56 and minimal lumen diameter; MD = -0.75, 95% CI: -0.89, -0.61), it showed better results at 12 months follow-up (late lumen loss; MD = -0.34, 95% CI: -0.62, -0.07). Conclusions: This meta-analysis showed that the DEB strategy is comparable to DES in the treatment of CCLs in terms of clinical outcomes. Although the DEB strategy had inferior acute angiographic results, it may offer better angiographic results at follow-up.

Procedural and clinical impact of intravascular lithotripsy for the treatment of peri-stent calcification. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2024; 61:16-23. [PMID: 37923647 DOI: 10.1016/j.carrev.2023.10.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 10/13/2023] [Accepted: 10/16/2023] [Indexed: 11/07/2023]
Abstract
BACKGROUND Use of intravascular lithotripsy (IVL) for treating peri-stent calcification is increasing. However, this indication remains 'off-label'. We aimed to investigate the efficacy and clinical outcomes of in-stent IVL. METHODS Patients from five European centers who underwent in-stent IVL were included between 2019 and 2023. Demographic, clinical, procedural and follow-up data were collected from electronic hospital records. Angiographic and intracoronary imaging (ICI) data were analyzed in a centralized core-laboratory. RESULTS Of 101 patients (71.2 ± 9.2 years), 56(55 %) received in-stent IVL for late stent failure (median 109 days post-PCI) due to calcific neoatherosclerosis or extra-stent calcification(late-IVL), while 45(45 %) underwent bail-out IVL due to stent infraexpasion (immediate-IVL). Both late-IVL and immediate-IVL significantly improved angiographic %diameter stenosis (73.7[59.6-89.8]% to 16.4 [10.4-26.9]%;p < 0.0001 and 28.6[22.5-43.3]% to 14.1[10.3-29.4]%;p < 0.0001, and minimum lumen area (MLA) (3.4 ± 1.2 to 8.6 ± 2.5 mm2;p < 0.002 and 5.4 ± 1.9 to 7.3 ± 1.9;p < 0.0001).Device(98 %) and procedural success(80 %) were high. MACE rates in-hospital (2 %), 30-days (3 %),6-months(5 %) and 1-year(7 %) were low and comparable in both groups. Acute diameter gain was lower in immediate-IVL (2.1 ± 0.7 mm vs. 0.5 ± 0.4 mm;p < 0.0001). This, however, was explained by significant differences in pre-IVL angiographic and ICI parameters (%diameter stenosis 73.7[59.6-89.8] vs. 28.6[22.5-43.3]%; p < 0.0001 and MLA (3.4 ± 1.2 vs 5.4 ± 1.9 mm2; p < 0.0001), whereas post-IVL percentage diameter stenosis (16.4(10.4-26.9) vs. 14.1(10.3-29.4);p = 0.914) and MLA (8.6 ± 2.5vs. 7.4 ± 1.9 mm2;p = 0.064) in late- and immediate-IVL were comparable. CONCLUSIONS IVL in-stent due to peri-stent calcification is an effective strategy, both late and immediately after stent implantation. Overall, MACE rates at short- and mid-term were low and comparable in both groups, although clinical findings should be taken with caution.

Abstract
Drug-eluting stents (DES) and balloons revolutionize atherosclerosis treatment by targeting hyperplastic tissue responses through effective local drug delivery strategies. This review examines approved and emerging endovascular devices, discussing drug release mechanisms and their impacts on arterial drug distribution. It emphasizes the crucial role of drug delivery in modern cardiovascular care and highlights how device technologies influence vascular behavior based on lesion morphology. The future holds promise for lesion-specific treatments, particularly in the superficial femoral artery, with recent CE-marked devices showing encouraging results. Exciting strategies and new patents focus on local drug delivery to prevent restenosis, shaping the future of interventional outcomes. In summary, as we navigate the ever-evolving landscape of cardiovascular intervention, it becomes increasingly evident that the future lies in tailoring treatments to the specific characteristics of each lesion. By leveraging cutting-edge technologies and harnessing the potential of localized drug delivery, we stand poised to usher in a new era of precision medicine in vascular intervention.

The Significance of Coronary Artery Calcification for Percutaneous Coronary Interventions. Healthcare (Basel) 2024; 12:520. [PMID: 38470631 PMCID: PMC10931248 DOI: 10.3390/healthcare12050520] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Revised: 02/19/2024] [Accepted: 02/20/2024] [Indexed: 03/14/2024] Open
Abstract
The prevalence of calcium deposits in coronary arteries grows with age. Risk factors include, e.g., diabetes and chronic kidney disease. There are several underlying pathophysiological mechanisms of calcium deposition. Severe calcification increases the complexity of percutaneous coronary interventions. Invasive techniques to modify the calcified atherosclerotic plaque before stenting have been developed over the last years. They include balloon- and non-balloon-based techniques. Rotational atherectomy has been the most common technique to treat calcified lesions but new techniques are emerging (orbital atherectomy, intravascular lithotripsy, laser atherectomy). The use of intravascular imaging (intravascular ultrasound and optical coherence tomography) is especially important during the procedures in order to choose the optimal strategy and to assess the final effect of the procedure. This review provides an overview of the role of coronary calcification for percutaneous coronary interventions.

Abstract
BACKGROUND Percutaneous coronary interventions in heavily calcified coronary lesions are associated with technical difficulties and the worse prognosis. Lesion preparation is important to reduce complications and improve outcomes. The aim of this study is to compare the results of rotational atherectomy (RA) and intravascular lithotripsy (IVL) at achieving optimal stent implantation using intravascular ultrasound criteria. METHODS Retrospective, single-center study comparing patients with heavily calcified coronary lesions that underwent percutaneous coronary interventions using RA or IVL. RESULTS IN TOTAL 25 patients (13 in the RA group and 12 in the IVL group) were included. Reference vessel diameter was similar between the groups [2.59 (2.51-3.63) mm in the RA group vs. 2.79 (2.59-3.16) mm in the IVL group; P = 0.89], as were minimal lumen area [1.02 (0.80-1.23) mm vs. 1.40 (1.01-1.40) mm; P = 0.43] and diameter stenosis [60.4% (52.3-72.3) vs. 56.1% (47.8-61.3); P = 0.56). The final minimal lumen area was significantly larger in the IVL group [7.6 mm2 (5.8-8.6) vs. 5.4 mm2 (4.5-6.2); P = 0.01] as were lumen area gain [4.1 mm2 (2.6-5.9) vs. 2.3 mm2 (1.4-3.6); P = 0.01] and final stent volume [491.2 mm3 (372.2-729.8) vs. 326.2 mm3 (257.1-435.4); P = 0.03]. In the RA group, 69.2% of the patients achieved the preestablished intravascular ultrasound-based criteria for successful stent implantation, vs. 100% of the patients in the IVL group (P = 0.04). CONCLUSION Patients in the IVL group achieved the Intravascular Ultrasound Versus Angiography-Guided Drug-Eluting Stent Implantation trial criteria of successful stent implantation more frequently than those treated with RA.

Abstract
Left main (LM) coronary artery disease is a high-risk lesion subset, with important prognostic implications for the patients. Recent advances in the field of interventional cardiology have narrowed the gap between surgical and percutaneous approach of this complex lesion setting. However, the rate of repeat revascularization remains higher in the case of percutaneous coronary intervention (PCI) on long-term follow-up. As such, the need for better stent optimization strategies has led to the development of intravascular imaging techniques, represented mainly by intravascular ultrasound (IVUS) and optical coherence tomography (OCT). These techniques are both able to provide excellent pre- and post-PCI guidance. While IVUS is an established modality in optimizing LM PCI, and is recommended by international revascularization guidelines, data and experience on the use of OCT are still limited. This review paper deeply analyzes the current role of OCT imaging in the setting of LM disease, particularly focusing on its utility in assessing plaque morphology and distribution, vessel dimensions and proper stent sizing, analyzing mechanisms of stent failure such as malapposition and underexpansion, guiding bifurcation stenting, as well as offering a direct comparison with IVUS in this critical clinical scenario, based on the most recent available data.

Abstract
BACKGROUND AND AIM Interventional cardiologists face challenges in managing chronic total occlusion (CTO) lesions, with conflicting results when comparing rotational atherectomy (RA) to conventional PCI. This meta-analysis aims to provide a critical evaluation of the safety and feasibility of RA in CTO lesions. METHODS PubMed, Scopus, Web of Science, Ovid, and Cochrane central library until April 2023 were searched for relevant studies. MACE was our primary outcomes, other outcomes were all cause of death, cardiac death, MI, and TVR. Also, we reported angiographic outcomes as technical success, procedural success, and procedural complications in a random effect model. The pooled data was analyzed using odds ratio (OR) with its 95% CI using STATA 17 MP. RESULTS Seven studies comprising 5494 patients with a mean follow-up of 43.1 months were included in this meta-analysis. Our pooled analysis showed that RA was comparable to PCI to decrease the incidence of MACE (OR = 0.98, 95% CI [0.74 to 1.3], p = 0.9). Moreover, there was no significant difference between RA and conventional PCI in terms of other clinical or angiographic outcomes. CONCLUSION Our study showed that RA had comparable clinical and angiographic outcomes as conventional PCI in CTO lesions, which offer interventional cardiologists an expanded perspective when addressing calcified lesions.

Rotational atherectomy combined with cutting balloon to optimise stent expansion in calcified lesions: the ROTA-CUT randomised trial. EUROINTERVENTION 2024; 20:75-84. [PMID: 38165112 PMCID: PMC10756220 DOI: 10.4244/eij-d-23-00811] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 10/17/2023] [Indexed: 01/03/2024]
Abstract
BACKGROUND Percutaneous coronary intervention (PCI) of calcified lesions remains challenging for interventionalists. AIMS We aimed to investigate whether combining rotational atherectomy (RA) with cutting balloon angioplasty (RA+CBA) results in more optimal stent expansion compared with RA followed by non-compliant balloon angioplasty (RA+NCBA). METHODS ROTA-CUT is a prospective, multicentre, randomised trial of 60 patients with coronary artery disease undergoing PCI of moderately or severely calcified lesions with drug-eluting stent implantation. Patients were randomised 1:1 to either RA+CBA or RA+NCBA. The primary endpoint was the minimum stent area on intravascular ultrasound (IVUS). Secondary endpoints included minimum lumen area and stent expansion assessed by IVUS and acute lumen gain, final residual diameter stenosis and minimum lumen diameter assessed by angiography. Clinical endpoints were obtained at 30 days. RESULTS The mean age was 71.1±9.4 years, and 22% were women. The procedural details of RA were similar between groups, as were procedure duration and contrast use. Minimum stent area was similar with RA+CBA versus RA+NCBA (6.7±1.7 mm2 vs 6.9±1.8 mm2; p=0.685). Furthermore, there were no significant differences regarding the other IVUS and angiographic endpoints. Procedural complications were rare, and 30-day clinical events included 2 myocardial infarctions and 1 target vessel revascularisation in the RA+CBA group and 1 myocardial infarction in the RA+NCBA group. CONCLUSIONS Combining RA with CBA resulted in a similar minimum stent area compared with RA followed by NCBA in patients undergoing PCI of moderately or severely calcified lesions. RA followed by CBA was safe with rare procedural complications and few clinical adverse events at 30 days.

Abstract
BACKGROUND Debulking devices are necessary to treat severe calcified lesions. OAS has a unique characteristic that the burr moves forward and backward. There are few studies reporting the differences of ablation style between only-antegrade and only-retrograde OAS. AIMS The aim of this study was to evaluate the difference of ablation style between only-antegrade and only-retrograde orbital atherectomy system (OAS) using an artificial pulsatile heart model (HEARTROID system®) and optical coherence tomography (OCT). METHODS The calcified lesion model was inserted into the mid of left anterior descending in the HEARTROID®. Only-antegrade and only-retrograde ablation of OAS were conducted for each five lesions. Pre-OCT, OCT after low speed debulking and OCT after high speed debulking were conducted. The width and the depth of debulked area, the debulked area and the direction of debulked area were investigated. RESULTS In all of 210 cross-sections, 91 debulked cross sections were chosen for analysis. Only-antegrade group had 47 debulked cross-sections, and only-retrograde group 44 cross-sections. In the evaluation of OCT after high speed debulking, the debulked area (0.76 mm2 [0.58-0.91] vs. 0.53 mm2 [0.36-0.68], p < 0.001) and the depth of debulked area (0.76 mm [0.58-0.91] vs. 0.53 mm [0.36-0.68], p < 0.001) were significantly higher in only-antegrade group compared to only-retrograde group. The debulked bias and the width of debulked area are not significantly different between the two groups. CONCLUSIONS Compared to only-retrograde debulking, only-antegrade debulking acquired larger debulked area because of larger cutting depth, although the debulked bias and the width of debulked area were comparable between the two groups.

Abstract
BACKGROUND Patients who undergo percutaneous coronary intervention (PCI) with rotational atherectomy (RA) are at high risk of adverse clinical outcomes, and there are few clinical risk stratification tools for these patients. METHODS We conducted a study with 196 patients who underwent PCI with RA out of 7391 patients who underwent PCI using a multicenter, prospective cohort registry. Patients were divided into three groups according to the tertiles of the Thrombolysis in Myocardial Infarction (TIMI) Risk Score for Secondary Prevention (TRS 2°P): 65 patients in the T1 group (TRS 2°P < 3), 66 patients in the T2 group (TRS 2°P = 3), and 65 patients in the T3 group (TRS 2°P > 3). The primary endpoint was the cumulative 2-year incidence of major adverse cardiovascular and cerebrovascular events (MACCE), defined as a composite of cardiac death, acute coronary syndrome, and ischemic stroke. RESULTS Cumulative 2-year MACCE occurred in 41 patients (24 %) during the follow-up period. The cumulative incidence of MACCE was significantly higher in the T3 group than in the T1 group (log-rank test, p = 0.02). Multivariate Cox analyses revealed that the T3 group was associated with an increased risk of MACCE compared to that of the T1 group (adjusted hazard ratio, 2.66; 95 % confidence interval, 1.04-6.77; p = 0.04). The addition of TRS 2°P to conventional risk factors, including male sex, number of diseased vessels, and low-density lipoprotein cholesterol levels, improved the net reclassification improvement (NRI) and integrated discrimination improvement (IDI) (NRI 0.39, p = 0.027; IDI 0.072, p < 0.001). CONCLUSIONS Atherothrombotic risk stratification using TRS 2°P was useful in identifying high-risk patients with heavily calcified lesions following RA.

Chronic total occlusion rotational atherectomy (CTO RA) versus non-CTO RA in coronary artery disease: A meta-analysis of clinical outcomes and complications. AMERICAN HEART JOURNAL PLUS : CARDIOLOGY RESEARCH AND PRACTICE 2023; 36:100345. [PMID: 38510099 PMCID: PMC10945990 DOI: 10.1016/j.ahjo.2023.100345] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 10/31/2023] [Accepted: 11/02/2023] [Indexed: 03/22/2024]
Abstract
Background Chronic total occlusion rotational atherectomy (CTO RA) is an emerging intervention in coronary artery disease (CAD), although data comparing its outcomes and complications with non-CTO RA are scarce. We sought to evaluate the outcomes of RA in CTO lesions compared to those in non-CTO lesions by performing a meta-analysis. Methods We conducted a systematic review and meta-analysis of studies comparing the clinical outcomes and complications between CTO RA and non-CTO RA in patients with CAD. We searched PUBMED, CINAHL, EMBASE and Cochrane Central Register of Clinical Trials for any studies that compared the outcomes of RA in CTO and non-CTO lesions. The outcomes analyzed included in-hospital major adverse cardiovascular events (MACE), target vessel revascularization (TVR), angiographic success, procedural success, periprocedural complications, coronary perforation, and all-cause mortality. Results Four studies with a total of 1868 patients were included, spanning from 2018 to 2022, from Germany, Taiwan, and Korea. The median age of included patients was 71. The rate of the pooled results indicated a moderate, non-significant increase in in-hospital MACE and TVR for CTO RA compared to non-CTO RA. There was a small, non-significant decrease in angiographic and procedural success in CTO RA compared to non-CTO RA. CTO RA was associated with a non-significant increase in periprocedural complications and a significant increase in coronary perforation compared to non-CTO RA. All-cause mortality showed a non-significant increase in the CTO RA group. Conclusion This meta-analysis provides evidence that while CTO RA may be associated with a higher risk of coronary perforation, the risk of other outcomes including MACE, TVR, and all-cause mortality is not significantly different compared to non-CTO RA. More research is needed to further understand these relationships and to optimize treatment strategies in patients with CAD undergoing CTO RA.

Abstract
Iatrogenic coronary artery dissections (ICAD) are rare but potentially devastating complications during coronary angiography and percutaneous coronary interventions (PCI). Intima media complex separation may be produced either by the catheter tip or during PCI. Patient characteristics and procedure related risk factors are intimately linked to catheter induced ICAD over diagnostic angiography. Moreover, the increasing complexity of patients undergoing PCI, which frequently involves treatment of heavily calcified or occluded vessels, has increased the likelihood of dissections during PCI. A prompt recognition, along with a prompt management (either percutaneous, surgical or even careful watching), are key in preventing catastrophic consequences of ICAD, such as left ventricular dysfunction, cardiogenic shock, periprocedural myocardial infarction (MI) or cardiac death. This review aims to summarize the main updates concerning the pathophysiology, highlight key risk factors and suggest recommendations in management and treatment of ICAD.

Management strategies for heavily calcified coronary stenoses: an EAPCI clinical consensus statement in collaboration with the EURO4C-PCR group. Eur Heart J 2023; 44:4340-4356. [PMID: 37208199 DOI: 10.1093/eurheartj/ehad342] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2022] [Revised: 05/14/2023] [Accepted: 05/16/2023] [Indexed: 05/21/2023] Open
Abstract
Since the publication of the 2015 EAPCI consensus on rotational atherectomy, the number of percutaneous coronary interventions (PCI) performed in patients with severely calcified coronary artery disease has grown substantially. This has been prompted on one side by the clinical demand for the continuous increase in life expectancy, the sustained expansion of the primary PCI networks worldwide, and the routine performance of revascularization procedures in elderly patients; on the other side, the availability of new and dedicated technologies such as orbital atherectomy and intravascular lithotripsy, as well as the optimization of the rotational atherectomy system, has increased operators' confidence in attempting more challenging PCI. This current EAPCI clinical consensus statement prepared in collaboration with the EURO4C-PCR group describes the comprehensive management of patients with heavily calcified coronary stenoses, starting with how to use non-invasive and invasive imaging to assess calcium burden and inform procedural planning. Objective and practical guidance is provided on the selection of the optimal interventional tool and technique based on the specific calcium morphology and anatomic location. Finally, the specific clinical implications of treating these patients are considered, including the prevention and management of complications and the importance of adequate training and education.

Coronary intravascular lithotripsy and rotational atherectomy for severely calcified stenosis: Results from the ROTA.shock trial. Catheter Cardiovasc Interv 2023; 102:823-833. [PMID: 37668088 DOI: 10.1002/ccd.30815] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2023] [Revised: 06/07/2023] [Accepted: 08/14/2023] [Indexed: 09/06/2023]
Abstract
BACKGROUND Severely calcified coronary lesions present a particular challenge for percutaneous coronary intervention. AIMS The aim of this randomized study was to determine whether coronary intravascular lithotripsy (IVL) is non-inferior to rotational atherectomy (RA) regarding minimal stent area (MSA). METHODS The randomized, prospective non-inferiority ROTA.shock trial enrolled 70 patients between July 2019 and November 2021. Patients were randomly (1:1) assigned to undergo either IVL or RA before percutaneous coronary intervention of severely calcified coronary lesions. Optical coherence tomography was performed at the end of the procedure for primary endpoint analysis. RESULTS The primary endpoint MSA was lower but non-inferior after IVL (mean: 6.10 mm2 , 95% confidence interval [95% CI]: 5.32-6.87 mm2 ) versus RA (6.60 mm2 , 95% CI: 5.66-7.54 mm2 ; difference in MSA: -0.50 mm2 , 95% CI: -1.52-0.52 mm2 ; non-inferiority margin: -1.60 mm2 ). Stent expansion was similar (RA: 0.83 ± 0.10 vs. IVL: 0.82 ± 0.11; p = 0.79). There were no significant differences regarding contrast media consumption (RA: 183.1 ± 68.8 vs. IVL: 163.3 ± 55.0 mL; p = 0.47), radiation dose (RA: 7269 ± 11288 vs. IVL: 5010 ± 4140 cGy cm2 ; p = 0.68), and procedure time (RA: 79.5 ± 34.5 vs. IVL: 66.0 ± 19.4 min; p = 0.18). CONCLUSION IVL is non-inferior regarding MSA and results in a similar stent expansion in a random comparison with RA. Procedure time, contrast volume, and dose-area product do not differ significantly.

Prognostic Impact of Atrial Fibrillation in Patients with Heavily Calcified Coronary Artery Disease Receiving Rotational Atherectomy. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1808. [PMID: 37893526 PMCID: PMC10608542 DOI: 10.3390/medicina59101808] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 09/02/2023] [Accepted: 10/08/2023] [Indexed: 10/29/2023]
Abstract
Background and Objectives: Although both rotational atherectomy (RA) and atrial fibrillation (AF) have a high thrombotic risk, there have been no previous studies on the prognostic impact of AF in patients who undergo percutaneous coronary intervention (PCI) using RA. Thus, the aim of the present study was to determine the prognostic impact of AF in patients undergoing PCI using RA. Materials and Methods: A total of 540 patients who received PCI using RA were enrolled between January 2010 and October 2019. Patients were divided into AF and sinus rhythm groups according to the presence of AF. The primary endpoint was net adverse clinical events (NACEs) defined as a composite outcome of all-cause death, myocardial infarction, target vessel revascularization, cerebrovascular accident, or total bleeding. Results: Although in-hospital adverse events showed no difference between those with AF and those without AF (in-hospital events, 54 (11.0%) vs. 6 (12.2%), p = 0.791), AF was strongly associated with an increased risk of NACE at 3 years (NACE: hazard ratio, 1.880; 95% confidence interval, 1.096-3.227; p = 0.022). Conclusions: AF in patients who underwent PCI using RA was strongly associated with poor clinical outcomes. Thus, more attention should be paid to thrombotic and bleeding risks.

Early experience of intravascular lithotripsy in unprotected calcified left main coronary artery disease. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2023; 55:33-41. [PMID: 37127480 DOI: 10.1016/j.carrev.2023.04.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Revised: 04/19/2023] [Accepted: 04/21/2023] [Indexed: 05/03/2023]
Abstract
BACKGROUND Treatment of unprotected severely calcified left main coronary artery (LMCA) disease is a complex interventional procedure. Intravascular lithotripsy (IVL) and rotational atherectomy (RA) are safe and effective methods of treating coronary calcification in the non-LMCA setting. This retrospective analysis assessed the feasibility of IVL versus RA in unprotected LMCA disease. METHODS We analyzed IVL and RA procedures performed at a large tertiary hospital in the Northeast of England from January 1, 2019 to April 31, 2022. Major safety and efficacy endpoints were procedural and angiographic success, defined by stent delivery with <50 % residual stenosis and without clinical or angiographic complications, respectively. Another important clinical endpoint was the composite of major adverse cardiac events (MACE) at 1 year. RESULTS From 242 patients, 44 had LMCA IVL, 81 had LMCA RA and 117 had non-LMCA IVL. Patients with LMCA disease were older and more likely to have aortic stenosis. IVL was a second-line or bailout technique in 86.4 % LMCA and 92.2 % non-LMCA cases. Procedural and angiographic success rates were ≥ 84 % across all groups (p > 0.05). In 3 LMCA IVL and 3 LMCA RA cases arrhythmias and cardiac tamponade complicated the procedures respectively. At 1 year, MACE occurred in 10/44 (22.7 %) LMCA IVL, 16/81 (19.8 %) LMCA RA and 25/117 (21.4 %) cases (p > 0.05). CONCLUSION In our single center retrospective analysis, IVL is feasible in unprotected calcified LMCA as a second-line and third-line adjuvant calcium modification technique. Its use in unprotected calcified LMCA disease should be formalized with the undertaking of large randomized controlled trials.

Feasibility of rotational atherectomy in patients with acute coronary syndrome: favorable in-hospital outcomes and clinical importance of complexed coronary atherosclerosis. Heart Vessels 2023; 38:1193-1204.

Abstract
The feasibility of rotational atherectomy (RA) during percutaneous coronary intervention (PCI) in patients who present with acute coronary syndrome (ACS) remains fully unsettled. We retrospectively evaluated 198 consecutive patients who underwent RA during PCI from 2009 to 2020. All patients underwent intracoronary imaging (intravascular ultrasound 96.5%, optical coherence tomography 9.1%, both 5.6%) during PCI. Patients who underwent RA during PCI were divided into two groups: ACS (n = 49; unstable angina pectoris, n = 27; non-ST-elevation myocardial infarction, n = 18, and ST-elevation myocardial infarction, n = 4) and chronic coronary syndrome (CCS) (n = 149). The RA procedural success rate was comparable between in the ACS and CCS groups (93.9 vs. 89.9%, P = 0.41). No significant differences were observed in procedural complications and in-hospital death between the groups. The incidence of major adverse cardiovascular event (MACE) after 2 years was significantly higher in ACS group compared with CCS group (38.7 vs. 17.4%, log-rank P = 0.002). Multivariable Cox regression analysis identified SYNTAX score or CABG SYNTAX score > 22 (hazard ratio (HR) 2.66, 95% confidence interval (CI) 1.40-5.06, P = 0.002) and mechanical circulatory support during the procedure (HR 2.61, 95% CI 1.21-5.59, P = 0.013) as predictors of MACE at 2 years, but not ACS on index admission (HR 1.58, 95% CI 0.84-2.99, P = 0.151). RA procedure is feasible as a bail-out strategy for ACS lesions. However, more complexed coronary atherosclerosis and mechanical circulatory support during RA procedure, but no ACS lesions were associated with worse mid-term clinical outcomes.

Impact of Calcium Eccentricity on the Safety and Effectiveness of Coronary Intravascular Lithotripsy: Pooled Analysis From the Disrupt CAD Studies. Circ Cardiovasc Interv 2023; 16:e012898. [PMID: 37847770 PMCID: PMC10573097 DOI: 10.1161/circinterventions.123.012898] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Accepted: 07/27/2023] [Indexed: 10/19/2023]
Abstract
BACKGROUND Coronary intravascular lithotripsy (IVL) safely facilitates successful stent implantation in severely calcified lesions. This analysis sought to determine the relative impact of lesion calcium eccentricity on the safety and effectiveness of IVL using high-resolution optical coherence tomography imaging. METHODS Individual patient-level data (n=262) were pooled from 4 distinct international prospective studies (Disrupt CAD I, II, III, and IV) and analyzed by an independent optical coherence tomography core laboratory. IVL performance in eccentric versus concentric calcification was analyzed by dividing calcified lesions into quartiles (≤180° [most eccentric], 181°-270°, 271°-359°, and 360° [concentric]) by maximum continuous calcium arc. RESULTS In the 230 patients with clear imaging field on optical coherence tomography, there were no differences in preprocedure minimum lumen area, diameter stenosis, or maximum calcium thickness. The calcium length and volume index increased progressively with increasing mean and maximum continuous calcium arc (ie, concentricity). Conversely, the minimum calcium thickness decreased progressively with increasing concentricity. Post-procedure, the number of calcium fractures, fracture depth, and fracture width increased with increasing concentricity, with a 4-fold increase in the number of fractures in lesions with 360° of calcium arc compared with ≤180°. This increase in IVL-induced calcium fracture with increasing calcium burden and concentricity facilitated stent expansion and luminal gain such that there were no significant differences across quartiles. CONCLUSIONS IVL induced calcium fractures proportional to the magnitude of coronary artery calcium, including in eccentric calcium, leading to consistent improvements in stent expansion and luminal gain in both eccentric and concentric calcified coronary lesions.

Planned versus unplanned rotational atherectomy for plaque modification in severely calcified coronary lesions. Clin Res Cardiol 2023; 112:1252-1262. [PMID: 36928928 PMCID: PMC10449691 DOI: 10.1007/s00392-023-02176-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Accepted: 02/20/2023] [Indexed: 03/18/2023]
Abstract
BACKGROUND Evidence on the optimal timing of RA is scarce, although increased periprocedural complications for unplanned procedures have been reported. AIMS To compare planned versus unplanned use of rotational atherectomy (RA) for plaque modification in patients with severely calcified coronary lesions. METHODS Procedural and 1-year follow-up data of planned (n = 562 lesions in 448 vessels of 416 patients) and unplanned (n = 490 lesions in 435 vessels of 403 patients) RA between 2008 and 2020 were analyzed using the propensity score methods. The primary composite endpoint was target lesion failure (TLF), defined as cardiovascular death (CVD), target vessel myocardial infarction (TVMI), or target lesion revascularization (TLR). RESULTS Angiographic success was > 99% in both groups. Fluoroscopy time and contrast volume were significantly lower in planned RA (p < 0.001). Periprocedural complications including slow-flow, coronary dissection, and MI occurred in 4.8% after planned, and in 5.7% after unplanned RA. TLF occurred in 18.5% after planned, and in 14.7% after unplanned RA. Weighted subdistribution hazard ratios for TLFs revealed an unfavorable 1-year outcome for planned RA (sHR 1.62 [1.07-2.45], p = 0.023), which was driven by TLR (sHR 2.01 [1.18-3.46], p = 0.011), but not by CVD, or TVMI. No differences were observed in all-cause mortality. CONCLUSIONS Unplanned RA was associated with favorable outcome when compared to planned RA. Thus, RA can safely be reserved for lesions that prove untreatable by conventional means. Randomized and prospective trials are needed to evaluate a predominant use of rotational atherectomy as a bailout strategy in the future.

Abstract
With growing experience, technical improvements and use of newer generation drug-eluting stents (DES), recent data showed satisfactory acute and long-term results after rotational atherectomy (RA) in calcified coronary lesions. The randomized ROTAXUS and PREPARE-CALC trials compared RA to balloon-based strategies in two different time periods in the DES era. In this manuscript, we assessed the technical evolution in RA practice from a pooled analysis of the RA groups of both trials and established a link to further recent literature. Furthermore, we sought to summarize and analyze the available experience with RA in different patient and lesion subsets, and propose recommendations to improve RA practice. We also illustrated the combination of RA with other methods of lesion preparation. Finally, based on the available evidence, we propose a simple and practical approach to treat severely calcified lesions.

Abstract
Clinical outcomes in patients with reduced left ventricular systolic function undergoing rotational atherectomy (RA) for percutaneous coronary intervention (PCI) remain understudied. Our study sought to evaluate the impact of RA-PCI in patients with LV systolic dysfunction on long-term outcomes. Between 2015 and 2019, 4941 patients with reduced LV function (rEF) undergoing PCI (with or without RA) were included in the hospital database. The primary endpoint was in-hospital major adverse cardiovascular and cerebral events (MACCE). The secondary endpoint was 3-year MACCE. In-hospital MACCE rates were significantly higher in RA-PCI compared to standard PCI without RA (PCI) (7.6% vs. 3.9%, p = 0.0009). However, 3-years MACCE rates were similar in RA-PCI and PCI (26.40% vs. 26.6%, p = 0.948). In conclusion, RA-PCI in patients with rEF is feasible, safe, and shows similar long-term results to PCI.

Abstract
Ischemic coronary artery disease in all its forms remains the main cause of death worldwide. Coronary artery bifurcation lesions are a challenge because of their complexity and possible complications. The goal of treating bifurcation lesions is the optimal revascularization of the main vessel without compromising the side branch. Although the study of bifurcation stenting aims to keep the side branch viable, the outcomes regarding major acute cardiovascular events and survivability are related to the optimal treatment of the main vessel. There are many trials that have tried to evaluate the best technique to use with respect to bifurcation lesions, and early studies support provisional stenting as the election treatment. More recent trials highlighted the superior outcomes of the double kissing crush technique used on unprotected distal left main bifurcation lesions. In patients with acute myocardial infarction, two-stent techniques were avoided because of the prolonged procedural time in unstable patients, with high risks of complications. We present the case of a 53-year-old woman with multiple cardiovascular risk factors (dyslipidemia, hypertension, active cancer, post-COVID-19 state) and acute antero-lateral myocardial infarction who underwent primary coronary intervention with the use of the TAP technique for stenting the bifurcation culprit coronary lesion (left anterior descendent artery and first diagonal artery).

Abstract
Rotational atherectomy (RA) is an endovascular procedure to ablate calcified plaque and is an integral tool for complex percutaneous coronary intervention (PCI). Rotational atherectomy increases the risk of periprocedural complications. One of the major complications of RA is coronary perforation, which has a reported incidence of up to 2%. It is usually identified and managed within the procedure. Rarely, there are delayed and unanticipated complications that can be missed, causing significant morbidity and mortality. We present a rare case of a patient with a late presentation of cardiac tamponade days after a complex PCI with RA.

Abstract
Present research on the influence of gender on the treatment of coronary artery disease (CAD) and the outcome after percutaneous coronary intervention (PCI) is inconsistent. Sex differences in the presentation of CAD and the success after treatment have been described. We intend to compare the male and female sex in the procedure and the long-term outcome of Rotational Atherectomy (RA). A total of 597 consecutive patients (20.3% female and 79.7% male, mean age 75.3 ± 8.9 years vs. 72.7 ± 9 years, p < 0.001) undergoing Rotational Atherectomy between 2015 and 2020 were enrolled in the analysis. Demographic and clinical data were registered. In-hospital, 1-year, and 3-year MACCEs (major adverse cardiac and cerebrovascular events) were calculated. Women presented more often with myocardial infarction (23.9% vs. 14.9%, p = 0.017). The intervention was mainly performed via femoral access compared to radial access (65.4% vs. 33.6%, p = 0.002). Women had a smaller diameter of the balloon predilatation compared to men (2.8 ± 0.5 mm vs. 3.15 ± 2.4 mm, p < 0.05) and a smaller maximum diameter of the implanted stent (3.5 ± 1.2 mm vs. 4.10 ± 6.5 mm, p = 0.01). In-hospital, 1-year-, and 3-year MACCEs did not differ between the sexes. After a multivariate analysis, no difference between men and women could be detected. In conclusion, this analysis shows differences between women and men in periprocedural characteristics but does not show any differences after RA regarding in-hospital, 1-year-, and 3-year MACCEs.

Abstract
The amount of coronary calcium strongly correlates with the degree of atherosclerosis and, therefore, with the rate of future cardiac events. Calcified coronary lesions still represent a challenge for interventional cardiologists, bringing not only a higher risk of immediate complications during percutaneous coronary interventions (PCI), but also a higher risk of late stent failure due to under-expansion and/or malapposition, and therefore, have a relevant prognostic impact. Accurate identification of the calcified plaques together with the analysis of their distribution pattern within the vessel wall by intracoronary imaging is important to improve the successful treatment of these lesions. The aim of this review is to guide readers through the assessment of the calcified plaque distribution using intracoronary imaging in order to select the best devices and strategies for plaque debulking and lesion preparation.

Abstract
BACKGROUND Calcified lesions often lead to difficulty achieving optimal stent expansion. OPN non-compliant (NC) is a twin layer balloon with high rated burst pressure that may modify calcium effectively. METHODS Retrospective, multicenter registry in patients undergoing optical coherence tomography (OCT) guided intervention with OPN NC. Superficial calcification with > 180o arc and > 0.5 mm thickness, and/or nodular calcification with > 90o arc were included. OCT was performed in all cases before and after OPN NC, and after intervention. Primary efficacy endpoints were frequency of expansion (EXP) ≥80 % of the mean reference lumen area and mean final EXP by OCT, and secondary endpoints were calcium fractures (CF), and EXP ≥90 %. RESULTS 50 cases were included; 25 (50 %) superficial, and 25 (50 %) nodular. Calcium score of 4 in 42 (84 %) cases and 3 in 8 (16 %). OPN NC was used alone, or after other devices if further modification was needed, NC in 27 (54 %), cutting in 29 (58 %), scoring in 1 (2 %), IVL in 2 (4 %); or if non-crossable lesion, rotablation in 5 (10 %) cases. EXP ≥80 % was achieved in 40 (80 %) cases with mean final EXP post intervention of 85.7 % ± 8.9. CF were documented in 49 (98 %) cases; multiple in 37 (74 %). There were 1 flow limiting dissection requiring stent deployment and 3 non-cardiovascular related deaths in 6 months follow-up. No records of perforation, no-reflow or other major adverse events. CONCLUSION Among patients with heavy calcified lesions undergoing OCT guided intervention with OPN NC, acceptable expansion was achieved in most cases without procedure related complications.

[PMID: 36878760 DOI: 10.1016/j.carrev.2023.02.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 02/10/2023] [Accepted: 02/20/2023] [Indexed: 02/26/2023]
Abstract
BACKGROUND Intracoronary lithotripsy (IVL) is a safe and effective treatment for coronary calcification. Angiographic and intracoronary imaging follow-up have not yet been described. We aimed to describe the mid-term angiographic outcomes following IVL. METHODS Patients successfully treated with IVL in two tertiary referral hospitals were included. Repeat angiography and intracoronary imaging was performed. Quantitative coronary angiography (QCA) and optical coherence tomography (OCT) analyses were performed using dedicated workstations. RESULTS Twenty patients were included; mean age 67.1 years, left anterior descending artery 55 %. Median IVL balloon size was 3.0 mm and a median of 60 pulses were delivered per vessel. Percentage stenosis by QCA was 60 % [IQR 51-70] reducing to 20 % post stenting (p < 0.001). On OCT, 88.9 % had circumferential calcium. IVL resulted in fractures in 88.9 %. Resulting minimum stent expansion was 91.75 % [IQR 81.5-108]. Follow-up was at a median of 22.7 months [IQR16.4-25.5]. Percentage stenosis by QCA was 22.5 % [IQR 14-30] and not significantly different from the index procedure (p > 0.05). Minimum stent expansion by OCT was 85 % [IQR 72-97]. Late luminal loss was 0.15 mm [IQR -0.25 to 0.69]. Binary angiographic instent restenosis (ISR) was 10 % (2 of 20 patients). OCT demonstrated a predominantly homogenous neointimal pattern with high backscatter. CONCLUSION Following successful IVL treatment, repeat angiography demonstrated preserved stent parameters in the majority of patients with favorable vascular healing properties by OCT. A binary restenosis rate of 10 % was observed. These results suggest durable results following IVL treatment of severe coronary calcification however larger studies are warranted.

Impact of Clinical Presentation on Outcomes After Rotational Atherectomy in Patients Who Underwent Percutaneous Coronary Intervention. Am J Cardiol 2023; 201:252-259. [PMID: 37393727 DOI: 10.1016/j.amjcard.2023.05.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Revised: 04/18/2023] [Accepted: 05/07/2023] [Indexed: 07/04/2023]
Abstract
Rotational atherectomy (RA) is widely used in the percutaneous treatment of heavily calcified coronary artery lesions in patients with chronic coronary syndromes (CCS). However, the safety and efficacy of RA in acute coronary syndrome (ACS) is not well established and is considered a relative contraindication. Therefore, we sought to evaluate the efficacy and safety of RA in patients presenting with non-ST-elevation myocardial infarction (NSTEMI), unstable angina (UA), and CCS. Consecutive patients who underwent percutaneous coronary intervention with RA between 2012 and 2019 at a tertiary single center were included. Patients presenting with ST-elevation myocardial infarction (MI) were excluded. The primary end points of interest were procedural success and procedural complications. The secondary end point was the risk of death or MI at 1 year. A total of 2,122 patients who underwent RA were included, of whom 1,271 presented with a CCS (59.9%), 632 presented with UA (29.8%), and 219 presented with NSTEMI (10.3%). Although an increased rate of slow-flow/no-reflow was noted in the UA population (p = 0.03), no significant difference in procedural success or procedural complications, including coronary dissection, perforation, or side-branch closure, was noted (p = NS). At 1 year, there were no significant differences in death or MI between CCS and non-ST-elevation ACS (NSTE-ACS: UA + NSTEMI; adjusted hazard ratio 1.39, 95% confidence interval 0.91 to 2.12); however, patients who presented with NSTEMI had a higher risk of death or MI than CCS (adjusted hazard ratio 1.79, 95% confidence interval 1.01 to 3.17). Use of RA in NSTE-ACS was associated with similar procedural success without an increased risk of procedural complications compared with patients with CCS. Although patients presenting with NSTEMI remained at higher risk of long-term adverse events, RA appears to be safe and feasible in patients with heavily calcified coronary lesions presenting with NSTE-ACS.

Abstract
Axillary bromhidrosis, which involves the apocrine sweat glands, severely affects adolescents. The present study aimed to evaluate the effect of tumescent anesthesia technique combined with superficial fascia rotational atherectomy treatment for axillary bromhidrosis. The present retrospective study included a total of 60 patients with axillary bromhidrosis. These patients were divided into experimental and control groups. Patients in the control group were treated using the tumescent anesthesia technique combined with conventional surgery, while patients in the experimental group were treated using the anesthesia technique combined with superficial fascia rotational atherectomy. The intraoperative blood loss, operation time, histopathological examination and dermatology life quality index (DLQI) score were used to assess the treatment effect. The intraoperative blood loss and operation time were significantly lower in the experimental group compared with the control group. The histopathological results revealed that the sweat gland tissues in experiment group significantly decreased compared with that in control group. Furthermore, there was a significant improvement in axillary odor degree for postoperative patients, and the DLQI scores in experiment group were significantly lower compared with those in control group. The tumescent anesthesia technique combined with superficial fascia rotational atherectomy is a promising approach to treating patients with axillary bromhidrosis.

Drug-coated balloon strategy following orbital atherectomy for calcified coronary artery compared with drug-eluting stent: One-year outcomes and optical coherence tomography assessment. Catheter Cardiovasc Interv 2023. [PMID: 37210618 DOI: 10.1002/ccd.30689] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Accepted: 04/30/2023] [Indexed: 05/22/2023]
Abstract
BACKGROUND Percutaneous coronary intervention (PCI) for calcified coronary artery remains challenging in the drug-eluting stent (DES) era. While recent studies reported the efficacy of orbital atherectomy (OA) combined with DES for calcified lesion, the effectiveness of drug-coated balloon (DCB) following OA has not been fully elucidated. METHODS Between June 2018 and June 2021, 135 patients who received PCI for calcified de novo coronary lesions with OA were enrolled and divided into two groups; OA followed by DCB (n = 43) if the target lesion achieved acceptable preparation, or second- or third-generation DESs (n = 92) if the target lesion showed suboptimal preparation between June 2018 and June 2021. All patients underwent PCI with optical coherence tomography (OCT) imaging. The primary endpoint was 1-year major adverse cardiac event (MACE), that was a composite of cardiac death, nonfatal myocardial infarction, or target lesion revascularization. RESULTS Mean age was 73 years and 82% was male. In OCT analysis, maximum calcium plaque was thicker (median: 1050 µm [interquartile range (IQR): 945-1175 µm] vs. 960 µm [808-1100 µm], p = 0.017), calcification arc tended to larger (median: 265° [IQR: 209-360°] vs. 222° [162-305°], p = 0.058) in patients with DCB than in DES, and the postprocedure minimum lumen area was smaller in DCB compared with minimum stent area in DES (median: 3.83 mm2 [IQR: 3.30-4.52 mm2 ] vs. 4.86 mm2 [4.05-5.82 mm2 ], p < 0.001). However, 1 year MACE free rate was not significantly different between 2 groups (90.3% in DCB vs. 96.6% in DES, log-rank p = 0.136). In the subgroup analysis of 14 patients who underwent follow-up OCT imaging, late lumen area loss was lower in patients with DCB than DES, despite lower lesion expansion rate in DCB than DES. CONCLUSIONS In calcified coronary artery disease, DCB alone strategy (if acceptable lesion preparation was performed with OA) was feasible compared with DES following OA with respect to 1-year clinical outcomes. Our finding indicated using DCB with OA might be reduce late lumen area loss for severe calcified lesion.

Comparison of long-term outcome in patients with calcified stenosis treated with intravascular lithotripsy or with modified balloon angioplasty: a propensity score-adjusted study. Front Cardiovasc Med 2023; 10:1185422. [PMID: 37255702 PMCID: PMC10225498 DOI: 10.3389/fcvm.2023.1185422] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Accepted: 04/26/2023] [Indexed: 06/01/2023] Open
Abstract
Background The aim of this two-center, all-comers registry was to compare the effectiveness and safety of intravascular lithotripsy (IVL) to that of modified balloon angioplasty (MB). MB angioplasty using a cutting or scoring balloon is commonly used in patients with calcified coronary arteries. IVL is a new technology for lesion preparation. This is the first study to compare MB with IVL. Methods The cohort included all patients treated by MB angioplasty or IVL between 2019 and 2021. The primary endpoint was strategy success (<20% residual stenosis). The secondary endpoint was long-term safety outcomes [cardiac death, acute myocardial infarction (AMI), target lesion failure/revascularization (TVR)]. Quantitative coronary angiography (QCA) was performed in all patients. Primary and secondary endpoints were compared using inverse probability of treatment weighting (IPTW) for treatment effect estimation. Results A total of n = 86 patients were treated by IVL and n = 92 patients by MB angioplasty. The primary endpoint was reached in 152 patients (85.4%). Patients in the IVL group had less residual stenosis (5.8% vs. 22.8%; p = 0.001) in QCA. Weighted multivariable regression analysis revealed that IVL had a significant positive effect on reaching the primary endpoint of strategy success [odds ratio (OR) 24.58; 95% confidence interval (95% CI) 7.40-101.86; p = 0.001]. In addition, severe calcification was shown to result in a lower probability of achieving the primary endpoint (OR 0.08; 95% CI 0.02-0.24; p = 0.001). During the follow-up period (450 days) there was no difference in cardiovascular mortality rate [IVL (n = 5) 2.8% vs. MB (n = 3) 1.7%; p = 0.129]. Patients with unstable angina at the time of the index procedure had the highest probability of cardiovascular death [hazard ratio (HR) 7.136; 95% CI 1.248-40.802; p = 0.027]. No differences were found in long-term rates of AMI (IVL 1.7% vs. MB 2.8%; p = 0.399; IVL HR 2.73; 95% CI 0.4-17.0; p = 0.281) or TVR (IVL 5.6% vs. MB 9%; p = 0.186; IVL HR 0.78; 95% CI 0.277-2.166; p = 0.626). Conclusion IVL leads to a significantly better angiographic intervention outcome compared to MB angioplasty in our cohort. During long-term follow-up, no differences in cardiovascular mortality, rate of acute myocardial infarction, or target lesion failure/revascularization were observed.

Abstract
Debulking lesions with severe coronary artery calcification (CAC) is highly recommended to obtain good procedural and long-term success. Utilization and performance of coronary intravascular lithotripsy (IVL) after rotational atherectomy (RA) has not been thoroughly studied. This study aimed to evaluate the efficacy and safety of IVL with the Shockwave Coronary Rx Lithotripsy System in lesions with severe CAC as elective or bail-out strategy after RA. This observational, prospective, single-arm, multicenter, international, open-label Rota-Shock registry included patients with symptomatic coronary artery disease and lesions with severe CAC treated by percutaneous coronary intervention, including lesion preparation with RA and IVL, at 23 high-volume centers. Primary efficacy end point was procedural success, defined as final diameter stenosis <30% by quantitative coronary angiography. Primary safety end point was freedom from serious angiographic complications, which included >National Heart, Lung and Blood Institute type B dissection, perforation, abrupt closure, slow or no flow, final thrombolysis in myocardial infarction flow <3, and acute thrombosis. A total of 160 patients were enrolled between June 2020 and June 2022. The primary efficacy end point was observed in 155 patients (96.9%). The primary safety end point occurred in 145 cases (90.6%). Dissections >National Heart, Lung and Blood Institute type B occurred in 3 patients (1.9%), whereas slow or no flow occurred in 8 (5.0%), final thrombolysis in myocardial infarction flow <3 in 3 (1.9%), and perforation in 4 patients (2.5%). Free from inhospital major adverse cardiac and cerebrovascular events, including cardiac death, target vessel myocardial infarction, target lesion revascularization, cerebrovascular accident, definite/probable stent thrombosis, and major bleeding, occurred in 158 patients (98.7%). In conclusion, IVL after RA in lesions with severe CAC was effective and safe, with a very low incidence of complications as either elective or bail-out strategy.

Abstract
BACKGROUND Whether an eruptive or noneruptive target lesion calcified nodule (CN) portends worse acute and long-term clinical outcomes after stenting has not been established. OBJECTIVES The authors sought to compare acute and long-term clinical outcomes in eruptive CN vs noneruptive CN morphology. METHODS Using optical coherence tomography, an eruptive CN was defined as an accumulation of small calcium fragments protruding and disrupting the overlying fibrous cap, typically with small amount of thrombus. A noneruptive CN was defined as an accumulation of small calcium fragments with a smooth intact fibrous cap without an overlying thrombus. The primary endpoint was target lesion failure (TLF) including cardiac death, target vessel myocardial infarction, or clinically driven target lesion revascularization in patients with ≥6-month follow-up. RESULTS Among 3,231 patients with evaluable pre- and postintervention OCT, 236 patients had lesions with CNs (7.3%). After eliminating 4 secondary lesions and 6 patients without ≥6-month follow-up, 126 (54.8%) lesions with eruptive CNs and 104 (45.2%) lesions with noneruptive CNs formed the current report. Compared with noneruptive CNs, eruptive CNs were independently associated with greater stent expansion (89.2% ± 18.7% vs. 81.5% ± 18.9%; P = 0.003) after adjusting for morphologic and procedural factors. At 2 years, eruptive CNs trended toward more TLF compared with noneruptive CNs (Kaplan-Meier estimates, 19.8% vs 12.5%; P = 0.11) and significantly more target lesion revascularization (18.3% vs 9.6%; P = 0.04). In the adjusted model, eruptive CNs were independently associated with 2-year TLF (HR: 2.07; 95% CI: 1.01-4.50; P = 0.048). CONCLUSIONS Compared with noneruptive CN morphology, lesions with an eruptive CN appearance on optical coherence tomography had a worse poststent long-term clinical outcome despite better acute stent expansion.

The role of invasive and non-invasive imaging technologies and calcium modification therapies in the evaluation and management of coronary artery calcifications. Front Cardiovasc Med 2023; 10:1133510.

Abstract
The treatment of coronary artery disease (CAD) has advanced significantly in recent years due to improvements in medical therapy and percutaneous or surgical revascularization. However, a persistent obstacle in the percutaneous management of CAD is coronary artery calcification (CAC), which portends to higher rates of procedural challenges, post-intervention complications, and overall poor prognosis. With the advent of novel multimodality imaging technologies spanning from intravascular ultrasound to optical coherence tomography to coronary computed tomography angiography combined with advances in calcium debulking and modification techniques, CACs are now targets for intervention with growing success. This review will summarize the most recent developments in the diagnosis and characterization of CAC, offer a comparison of the aforementioned imaging technologies including which ones are most suitable for specific clinical presentations, and review the CAC modifying therapies currently available.

Abstract
Despite considerable improvement in diagnostic modalities and therapeutic options over the last few decades, the global burden of ischemic heart disease is steadily rising, remaining a major cause of death worldwide. Thus, new strategies are needed to lessen cardiovascular events. Researchers in different areas such as biotechnology and tissue engineering have developed novel therapeutic strategies such as stem cells, nanotechnology, and robotic surgery, among others (3D printing and drugs). In addition, advances in bioengineering have led to the emergence of new diagnostic and prognostic techniques, such as quantitative flow ratio (QFR), and biomarkers for atherosclerosis. In this review, we explore novel diagnostic invasive and noninvasive modalities that allow a more detailed characterization of coronary disease. We delve into new technological revascularization procedures and pharmacological agents that target several residual cardiovascular risks, including inflammatory, thrombotic, and metabolic pathways.

Abstract
Background Orbital atherectomy (OA) is used to prepare severely calcified coronary artery lesions before percutaneous coronary intervention (PCI). Intravascular ultrasound (IVUS) is used to determine the plaque volume and degree of stenosis within the arterial vessel. This study evaluated the safety and efficacy of OA for treating severely calcified coronary lesions and determined if IVUS impacted these outcomes. Methods We retrospectively collected data from a single center of patients with severe coronary artery calcification who underwent OA. The data on baseline characteristics and procedural and clinical outcomes were collected and analyzed. Results A total of 374 patients underwent OA. The mean age was 69 ± 12.7; 53.6% were Black, and 38% were female. Hypertension was present in 96% of the patients, followed by hyperlipidemia in 79.4%, diabetes mellitus in 53.7%, and chronic kidney disease (CKD) in 22.7%. More patients had presented with a non-ST-elevation myocardial infarction (NSTEMI) compared to ST-elevation myocardial infarction (STEMI) at 36.3% versus 4.3%, respectively. The radial artery was used in 35.4% of the cases, and the left anterior descending artery (LAD) was the most commonly treated vessel with OA at 61%, followed by the right coronary artery (RCA) at 30.7%. IVUS was utilized in 63.4% of cases. The most common complication of the procedure was perforation and dissection at an equal proportion of 1.3% among all patients. The no-reflow rate was 0.5%, and 0.5% developed post-procedural myocardial infarction (MI). The average length of stay was 4.7 days, while a marginal proportion, at 10.5%, had same-day discharge with no recorded complications. Conclusion In this analysis of patients with severely calcified coronary lesions, OA had low rates of major adverse cardiovascular events (MACE) and was considered a safe and effective treatment for complex coronary lesions.

Abstract
Intravascular lithotripsy can be used as an effective therapy for lesion preparation in severely calcified lesions. The mechanism, as shown by optical coherence tomography, is calcium fractures. The aforementioned modification is performed with minimal risk of perforation, no-reflow and a low incidence of flow-limiting dissection and myocardial infarctions. Other techniques, such as cutting or scoring balloons and rotational atherectomy have also been shown to increase luminal diameter, but other complications, such as distal embolization, induced by these treatment modalities, are a source of concern. This review describes a single-center study of all-comer patients, including those with complex characteristics. This therapy is very effective, with a very low risk of complications. In this article, we characterize the mechanism of action of the intravascular lithotripsy catheter, its optical coherence tomography validation, clinical applications, and comparison with other calcium-modifying technologies, as well as future directions, which can be used to improve the technology.

Abstract
INTRODUCTION Cardiovascular diseases (CVDs) are the leading cause of cardiovascular mortality and a major contributor to disability worldwide. The prevalence of CVDs is continuously increasing, and from 1990 to 2019, it has doubled. Global cardiovascular mortality has increased from 12.1 million in 1990 to 18.6 million cases in 2019. The development of therapeutic options for these diseases is at the forefront of interest concerning the extensive socio-economic consequences. Modern endovascular transcatheter therapeutic options contribute to the reduction of cardiovascular morbidity and mortality. AREAS COVERED The article concentrates on the triad of the most common causes of acute cardiovascular mortality and morbidity - myocardial infarction, ischemic stroke, and pulmonary embolism. Current evidence-based indications, specific interventional techniques, and remaining unsolved issues are reviewed and compared. A personal perspective on the possible implications for the future is provided. EXPERT OPINION Primary angioplasty for ST-segment elevation myocardial infarction is a well-established therapeutic option with proven mortality benefits. We suppose that catheter-based interventions for acute stroke will spread quickly from centers of excellence to routine clinical practice. We believe that ongoing research will provide a basis for the expansion of interventional treatment of pulmonary embolism soon.

The Target Vessel SYNTAX Score: A Novel Pre-Procedural Predictor for Contrast-Induced Acute Kidney Injury After Rotational Atherectomy. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2023; 47:18-24. [PMID: 36057490 DOI: 10.1016/j.carrev.2022.08.035] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Revised: 08/06/2022] [Accepted: 08/24/2022] [Indexed: 01/25/2023]
Abstract
BACKGROUND Rotational atherectomy (RA) is a complex procedure often associated with high contrast load. Known risk scores do not predict contrast-induced acute kidney injury (CI-AKI) before RA. We aim to investigate pre-procedural predictors of CI-AKI after RA, and the role of the target vessel SYNTAX score (tvSS). METHODS Among 295 patients who underwent RA between 01.2010 and 02.2019 at a single center, 49 developed CI-AKI. Those who were on chronic hemodialysis or with no available 48-h' kidney function tests were excluded. Predictors of CI-AKI were assessed in the whole cohort and those with no basal renal impairment. RESULTS The rate of CI-AKI was 16.6 %. The tvSS was 18 [14-23] vs. 12 [9-18] in patients with vs. without CI-AKI (p < 0.001). The tvSS cut-off value of 15 provided 75 % sensitivity and 60 % specificity for predicting CI-AKI. Consequently, a tvSS ≥15 emerged as an independent pre-procedural predictor for CI-AKI (adjusted OR: 4.94, 95 % CI: 2.38-10.20, p < 0.001), along with left ventricular ejection fraction (LVEF) ≤35 % (p = 0.016) and glomerular filtration rate (GFR) <45 ml/min (p = 0.004). TvSS was the only independent pre-procedural predictor for CI-AKI in patients with GFR ≥60 ml/min (p < 0.001). The contrast volume/GFR ratio and peri-procedural myocardial infarction (MI) were independent procedural predictors for CI-AKI in the whole cohort and in patients with basal GFR ≥60 ml/min. CONCLUSION CI-AKI after RA is frequent. The tvSS is an efficient pre-procedural predictor for CI-AKI after RA, along with LVEF ≤35 % and GFR <45 ml/min. Contrast volume/GFR ratio and peri-procedural MI emerged as procedural predictors for CI-AKI.

Sex-specific Inequalities in the Treatment of Severely Calcified Coronary Lesions: A Sub-analysis of the PREPARE-CALC Trial. Interv Cardiol 2023; 18:e02. [PMID: 36891034 PMCID: PMC9987508 DOI: 10.15420/icr.2022.07] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2022] [Accepted: 06/09/2022] [Indexed: 01/21/2023] Open
Abstract
Background: Coronary vessels in women may have anatomical and histological particularities. The aim of this study was to investigate sex-specific characteristics and outcomes of patients with calcified coronary arteries in the Prepare-CALC (Comparison of Strategies to Prepare Severely Calcified Coronary Lesions) trial. Methods: The Prepare-CALC trial randomised patients with severe coronary calcification to coronary lesion preparation either using modified balloons (MB; cutting or scoring) or rotational atherectomy (RA). Results: Of 200 randomised patients, 24% were women. Strategy success in general was similar between women (93.8%) and men (88.2%; p=0.27). For men, strategy success was significantly more common with an RA-based strategy than an MB-based strategy (98.7% in the RA group versus 77.3% in the MB group, p<0.001), whereas for women there was no evidence of a significant difference in strategy success between RA and MB (95.7% in the RA group versus 92% in the MB group, p>0.99, p for interaction between sex and treatment strategy=0.03). Overall, significant complications such as death, MI, stent thrombosis, bypass operation and perforations were rare and did not differ significantly by gender or treatment strategy. Plaque rupture and disrupted calcified nodules were more common in women. Conclusion: In a well-defined patient population with severely calcified coronary arteries, lesion preparation with an RA-strategy was superior to an MB-strategy in men. For women, both RA and MB strategies appear to have a similar success rate, although definitive conclusions are limited due to the small number of women in the trial.

Clinical research of drug-coated balloon after rotational atherectomy for severe coronary artery calcification. BMC Cardiovasc Disord 2023; 23:40. [PMID: 36681814 PMCID: PMC9867860 DOI: 10.1186/s12872-023-03071-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Accepted: 01/16/2023] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND Current research results show that drug-coated balloons (DCB) have unique advantages in the treatment of in-stent restenosis, small vessel disease, bifurcation lesions, and de novo lesions, but the data regarding rotational atherectomy (RA) followed by DCB treatment in calcified lesions, especially severe coronary artery calcification (CAC), are limited. METHODS A retrospective study was conducted on 318 individuals with severe CAC who underwent RA-assisted PCI at the First Affiliated Hospital of Zhengzhou University from May 2018 to July 2021. Among them, 57 patients (RA/DCB group) were treated with DCB, and 261 patients (RA/DES group) were treated with drug-eluting stents (DES). The two groups' clinical baseline data, lesion characteristics, intraoperative complications, in-hospital adverse events, and major adverse cardiovascular and cerebrovascular events (MACCE) were compared throughout the follow-up period. RESULTS The baseline clinical data, intraoperative complications, and in-hospital adverse events were not significantly different between the two groups. The anatomical categories in the RA/DES group were more complex and included left main coronary disease, bifurcation disease, and multivessel disease. Although target lesion revascularization (13.79% vs. 7.02%) and MACCE (18.77% vs. 12.28%) occurred more frequently in the RA/DES group than in the RA/DCB group, there was no statistically significant difference (p > 0.05). Multivariate Cox regression analysis showed that bifurcation lesions (HR 2.284, 95% CI 1.063-4.908, p = 0.034), total length of DCB/DES (HR 1.023, 95% CI 1.005-1.047, p = 0.014) and SYNTAX score (HR 1.047, 95% CI 1.013-1.082, p = 0.006) were independent risk factors for MACCE during the follow-up period. CONCLUSION Drug-coated balloon treatment after rotational atherectomy appears safe and effective in selected severe coronary artery calcification.

Abstract
Complex coronary artery disease with severe coronary calcification can be challenging to treat, with a higher risk of procedural complications and major adverse cardiac events. Intravascular lithotripsy (IVL) is a pioneering technology for the treatment of critically calcified coronaries. IVL utilizing localized pulsatile sonic pressure waves at low pressure provides a novel approach for lesion preparation of severely calcified plaques. The deliverability and ease of use are also likely to increase access and use of IVL, and combination therapy with other devices shows promise.
