In-hospital Outcomes of Rotational Atherectomy in ST-Elevation Myocardial Infarction: Results From the Multicentre ROTA-STEMI Network. Can J Cardiol 2023:S0828-282X(23)02034-2. [PMID: 38147962 DOI: 10.1016/j.cjca.2023.12.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 12/16/2023] [Accepted: 12/18/2023] [Indexed: 12/28/2023] Open
Abstract
BACKGROUND Although the use of rotational atherectomy (RA) is off-label in the setting of ST-elevation myocardial infarction (STEMI), it can be the only option in severely calcified culprit lesions to achieve procedural success. We sought to investigate the safety and feasibility of RA during primary percutaneous coronary intervention (PPCI). METHODS This was a retrospective observational study of patients who underwent RA during PPCI from 12 European centres. The main outcomes were procedural success (defined as successful stent implantation with final thrombolysis in myocardial infarction [TIMI] flow 3 and residual stenosis < 30%) and in-hospital mortality. A comparison of patients presenting with and without shock was performed. RESULTS In 104 patients with RA during STEMI, the mean age was 72.8 ± 9.1 years, and 35% presented with cardiogenic shock. Bailout RA was performed in 76.9% of cases. Mean burr size was 1.42 ± 0.21 mm. Procedural success was achieved in 86.5% of cases, with no difference between shocked and nonshocked patients (94.4% vs 82.4%; P = 0.13). In-hospital stent thrombosis occurred in 0.96%, perforation in 1.9% and burr entrapment in 2.9% of cases. In spite of equally high procedural success, in-hospital mortality was higher in shocked (50%) compared with nonshocked patients (1.5%; P < 0.0001). CONCLUSIONS Patients presenting with STEMI requiring RA, represent a high-risk population, frequently presenting with cardiogenic shock. In this analysis of selected patients, RA was performed as a bailout strategy in the majority, and, as such, RA seems to be feasible with a high procedural success rate. In the absence of cardiogenic shock, RA-facilitated PCI seems to be associated with low in-hospital mortality.

The Incidence of Complication in the Perioperative Period of Rotational Atherectomy in Patients With Acute Coronary Syndrome: A Retrospective Study of Low Speed Versus High Speed. Am J Cardiol 2023; 207:121-129. [PMID: 37734301 DOI: 10.1016/j.amjcard.2023.08.127] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 08/17/2023] [Accepted: 08/20/2023] [Indexed: 09/23/2023]
Abstract
The safety and efficacy of rotational atherectomy (RA) in patients with acute coronary syndrome (ACS) treated with different rotational speeds remain unclear. This was an observational retrospective registry study. Between February 2017 and January 2022, a total of 283 patients with ACS were treated with RA. The patients were divided into 2 groups: the low-speed group (130,000 to 150,000 rotations/min [rpm],182 cases) and the high-speed group (160,000 to 220,000 rpm, 101 cases) according to the maximum RA speed. The outcomes analyzed were procedural complications; incidence of heart failure, stent thrombosis, and cardiac death during hospitalization; and 30-day major cardiovascular and cerebrovascular events. Patients in the low-speed RA group had a higher incidence of vasospasm during RA (15.4% vs 6.9%, p = 0.040), whereas the incidence of slow blood flow was higher in the high-speed RA group (16.5% vs 27.7%, p = 0.031). There was no significant difference in other complications or in 30-day major cardiovascular and cerebrovascular events between the 2 groups. Moreover, logistic regression analysis identified rotational speed (160,000 to 220,000 rpm) as a predictor of slow flow during RA (odds ratio 1.900, 95% confidence interval 1.006 to 3.588, p = 0.048). For every 10,000-rpm increase in rotational speed, the risk of slow flow increased by 27% (odds ratio 1.273, 95% confidence interval 1.047 to 1.547, p = 0.015). In conclusion, patients with ACS treated with a lower RA speed (130,000 to 150,000 rpm) had a higher risk of vasospasm, whereas those treated with higher speeds (160,000 to 220,000 rpm) had a higher incidence of slow flow. High rotational speed (160,000 to 220,000 rpm) is an independent risk factor for slow flow during RA in patients with ACS.

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. [PMID: 37202532 DOI: 10.1007/s00380-023-02272-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Accepted: 05/10/2023] [Indexed: 05/20/2023]
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.

Rotational atherectomy of calcified coronary lesions: current practice and insights from two randomized trials. Clin Res Cardiol 2023; 112:1143-1163. [PMID: 35482101 PMCID: PMC10450020 DOI: 10.1007/s00392-022-02013-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2021] [Accepted: 03/21/2022] [Indexed: 11/26/2022]
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.

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.

Rotational atherectomy for chronically and totally occluded coronary lesions: A propensity score-matched outcomes study. Front Cardiovasc Med 2022; 9:1061812. [PMID: 36620617 PMCID: PMC9810983 DOI: 10.3389/fcvm.2022.1061812] [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: 10/05/2022] [Accepted: 11/29/2022] [Indexed: 12/24/2022] Open
Abstract
Background Despite advances being made in techniques and devices, certain chronic total occlusion (CTO) lesions remain uncrossable or undilatable. Rotational atherectomy (RA) is usually necessary for such lesions to achieve successful revascularization. Methods Information regarding consecutive patients who underwent coronary RA was retrieved from the catheterization laboratory database. Patients who underwent RA for CTO lesion refractory using other conventional devices were recruited, with propensity score-matched cases serving as controls. Results A total of 411 patients underwent coronary RA in the study period. Most patients had high-risk features (65.7% had acute coronary syndrome (ACS), 14.1% ischemic cardiomyopathy, and 5.1% cardiogenic shock), while only 20.2% of the patients had stable angina. Among them, 44 patients underwent RA for CTO lesions (CTO group), whereas the propensity score matched controls consist of 37 patients (non-CTO group). The baseline characteristics, high-risk features, coronary artery disease (CAD) vessel numbers, left ventricular function and biochemistry profiles of both groups were the same except for more patients with diabetes (67.6% vs. 45.5%, p = 0.046) in the non-CTO group and more 1.25 mm burr uses in the CTO group. There were no significant differences in acute procedural outcomes or incidence of acute contrast-induced nephropathy (CIN), and no patient demanded emergent CABG or died during the procedure. There was no significant difference in major adverse cardiovascular events (MACE), CV MACE or individual components between the two groups in the hospital, at 30, 90, and 180 days or at 1 year. Conclusion In comparison with the propensity risk factor scores-matched controls, there was no difference in procedural complications, acute CIN or clinical outcomes during various stages of RA for CTO lesions. RA for CTO patients was highly efficient and showed safety and outcome profiles similar to those for non-CTO lesions.

Abstract
Background: Heavily calcified lesions in acute coronary syndrome (ACS) still represent a challenging subset for percutaneous coronary intervention (PCI). Rota-lithotripsy—a marriage of rotational atherectomy and intravascular lithotripsy—has recently been introduced to clinical practice as a novel therapeutic option. Methods: This study is among the to present the 6-month clinical outcomes of rota-lithotripsy when performed in the ACS setting. The study cohort consisted of 15 consecutive ACS patients who underwent a rota-lithotripsy-PCI due to the presence of a highly calcified, undilatable lesion. Results: The procedural success ratio reached 100%. During the 6-month follow-up, in two of the patients, instances of MACE (major adverse cardiac events) occurred, including one fatal event. Additionally, during the observation period, one target lesion failure, due to subacute stent thrombosis, was identified. Conclusions: Rotational atherectomy with the subsequent use of shockwave intravascular lithotripsy appears to be a safe and effective therapeutic bail-out option for the management of highly calcified coronary artery lesions. Despite, these initial favorable outcomes, carrying out a large number of studies with long-term observations is still necessary in order to establish the potential benefits and shortcomings of rota-lithotripsy.

The Procedural and Clinical Outcomes of Rotational Atherectomy in Patients Presenting With Acute Myocardial Infarction. Front Cardiovasc Med 2022; 9:846564. [PMID: 35369302 PMCID: PMC8971549 DOI: 10.3389/fcvm.2022.846564] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Accepted: 02/21/2022] [Indexed: 11/13/2022] Open
Abstract
BackgroundRotational atherectomy (RA) is an indispensable tool used for calcified lesion preparation in percutaneous coronary intervention (PCI). However, use of RA in the setting of acute myocardial infarction (AMI) is challenged with limited clinical data.ObjectivesThis study aims to retrospectively investigate the procedural results, periprocedural complications, and clinical outcomes of RA in patients with AMI.MethodsAll possible consecutive patients who received RA in AMI from January 2009 to March 2018 in a single tertiary center were analyzed retrospectively. Patients without AMI during the study period were also enrolled for comparison.ResultsA total of 121 patients with AMI (76.0 ± 10.8 years, 63.6% males) and 290 patients without AMI were recruited. Among the AMI group, 81% of patients had non-ST-elevation myocardial infarction (NSTEMI) and 14% presented with cardiogenic shock. RA could be completed in 98.8% of patients in the AMI group and 98.3% in the non-AMI group (p = 1.00). The periprocedural complication rates were comparable between the AMI and non-AMI groups. The risks of in-hospital, 30-day, 90-day, and 1-year cardiovascular major adverse cardiac events (CV MACE) were significantly higher in the AMI group compared with the non-AMI group (in-hospital 13.2 vs. 2.8%, p < 0.001; 30-day 14.2 vs. 4.5%, p < 0.001; 90-day 20.8 vs. 6.9%, p < 0.001; 1-year 30.8 vs. 19.1%, p = 0.01). AMI at initial presentation and cardiogenic shock were predictors for both in-hospital CV MACE and 1-year CV MACE in multivariable binary logistic regression analysis. Other predictors for 1-year CV MACE included serum creatinine level and triple vessel disease.ConclusionRA in patients with AMI is feasible with a high procedural completion rate and acceptable periprocedural complications. Given unstable hemodynamics and complex coronary anatomy, the in-hospital and 1-year MACE rates remained higher in patients with AMI compared with patients without AMI.

Successful off-label use of rotational atherectomy in ST-segment elevation myocardial infarction: A case report. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2021; 40S:272-275.

Abstract
Rotational atherectomy (RA) in ST-segment elevation myocardial infarction (STEMI) is uncommon and its use in a thrombotic lesion is labelled a contraindication by its manufacturer due to the concern for further increase in platelet activation and aggregation by the spinning burr or distal embolization of the thrombotic material promoting no-reflow (NR). However, thrombus burden varies significantly in the STEMI setting and can be classified according to the thrombolysis in myocardial infarction (TIMI) thrombus grade (TG). This case demonstrates the successful off-label use of RA-assisted primary percutaneous coronary intervention to facilitate treatment of a heavily calcified ostial right coronary artery lesion with low thrombotic burden (TIMI TG 0) in an octogenarian STEMI patient. Atherectomy drug cocktails, intracoronary vasodilators, short burr runs and avoidance of rotating the burr at slower than minimum approved rotational speed contribute to atherectomy success and decrease the chances of NR.

Abstract
OBJECTIVES To assess the feasibility and safety of minimal-contrast percutaneous coronary intervention (PCI) using rotational atherectomy (RA) in patients with severe coronary calcification at high-risk of contrast-associated acute kidney injury (AKI). METHODS Twenty-six patients with advanced chronic kidney disease undergoing PCI with RA at three high-volume centres were included. Baseline intravascular ultrasound (IVUS) was performed to assess lesion morphology, and to guide burr-, balloon-, and stent-selection. Final result was assessed by IVUS and angiographically. Feasibility and safety were determined by procedural and in-hospital complications, and efficacy was assessed by freedom from contrast-associated AKI after PCI. Procedural and in-hospital outcome was compared to a propensity-matched population of standard RA PCI. RESULTS Mean glomerular filtration rate was 32 ± 17 ml/min/1.73 m2. In seven cases PCI was performed in the setting of acute coronary syndrome. The left main coronary artery was treated in 27.8% and a two-stent bifurcation technique in 44.4%. RA was more often performed electively compared to the standard RA cohort (92.3 vs. 50%; p = 0.0016). Angiographic success was achieved in 100% and documented with a median contrast amount of 12.5 ml [Range 4-43]. No in-hospital death or myocardial infarction was reported. Contrast-associated AKI occurred in one patient versus five patients in standard RA group (p = 0.19). Shorter fluoroscopy time and lower radiation dose were achieved as compared to standard RA. CONCLUSION A minimal-contrast RA approach with IVUS-guidance for treatment of complex calcified coronary lesions is feasible and safe with high success rate.

Abstract
Heavy calcification remains one of the greatest challenges in the treatment of coronary artery disease (CAD), especially in subjects with an acute coronary syndrome (ACS). In the present case series study of high-risk patients with ACS, including both STEMI and NSTEMI, we performed a rota-lithotripsy-a combination of rotational atherectomy with subsequent intravascular lithotripsy-as a novel bail-out strategy to facilitate stent delivery in a tortuous calcified coronary artery.

Rotational Atherectomy Complicated by Coronary Perforation Is Associated With Poor Outcomes: Analysis of 10,980 Cases From the British Cardiovascular Intervention Society Database. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2020; 28:9-13. [PMID: 32888836 DOI: 10.1016/j.carrev.2020.07.040] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2020] [Revised: 07/25/2020] [Accepted: 07/28/2020] [Indexed: 11/29/2022]
Abstract
BACKGROUND Rotational atherectomy (RA) during PCI is linked to a higher likelihood coronary perforations (CP). However, the evidence base on incidence, predictors and outcomes of this complication in RA-PCI remains limited. METHODS Using the British Cardiac Intervention Society database, data were analysed on all RA-PCI procedures in UK 2007-2014. Descriptive statistics and multivariate logistic regressions were used to examine baseline, procedural and outcome associations. RESULTS During 10,980 RA-PCI procedures, 167 CPs were recorded (1.52%) with a stable annual incidence. Baseline and procedural covariates associated with higher rates of RA perforation were number of stents used, female gender, smoking, and left-main stenosis. CP was significantly associated with shock, DC cardioversion, heart block, transfusion, emergency surgery, periprocedural MI, in-hospital major bleed, acute kidney injury, dissection, side branch loss and in-hospital death. CP was also associated with higher rates of in-hospital MACCE (OR 12.22, 95% CI 7.67-19.47), 30-day mortality (OR 10.02, 95% CI 5.87-17.09) and 12-month mortality (OR 3.90, 95% CI 2.53-6.02). CONCLUSIONS CP is more frequent in RA-PCI than all-comer PCI and is associated with a significant burden of morbidity and mortality. There are a limited number of baseline and procedural co-variates associated with CP in RA-PCI, making it difficult to predict.
