Abstract
Key points
The double kissing crush technique is a promising strategy for true bifurcation coronary diseases, although it is yet to be recognized as a “gold standard” because of its complexity.
A “one strategy fits all” approach is not applicable to bifurcation percutaneous coronary intervention (PCI) because of diversity.
New technologies may overcome this issue with diversity and support tailored PCI for true bifurcation coronary diseases.

One year results of coronary bifurcation revascularization with the re-POT provisional sequential technique. The CABRIOLET registry. Int J Cardiol 2024; 397:131632. [PMID: 38048882 DOI: 10.1016/j.ijcard.2023.131632] [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: 08/28/2023] [Revised: 11/18/2023] [Accepted: 11/30/2023] [Indexed: 12/06/2023]
Abstract
BACKGROUND Re-POT (proximal optimization technique (POT)) is a simple provisional sequential technique for percutaneous coronary bifurcation revascularization with better arterial geometry respect compared to classical techniques. Re-POT has demonstrated excellent mechanical and short-term clinical results. The multicenter CABRIOLET registry (NCT03550196) evaluate the long-term clinical benefit of the re-POT sequence in non-selected patients. METHODS All consecutive patients presenting a coronary bifurcation lesion for which provisional stenting was indicated were included in 5 european centers. Re-POT strategy was systematically attempted. The primary endpoint was target lesion failure (TLF), comprising cardiac death, myocardial infarction, stent thrombosis and target lesion revascularization (TLR) at 12 months' follow-up. The secondary endpoints were the individual components of the primary endpoint, all-cause death, target vessel failure (TVF) and target vessel revascularization (TVR). Complex bifurcation was defined as Medina 0.1.1 or 1.1.1. RESULTS A total of 500 patients aged 67.7 ± 11.7 years, 78.4% male, were included from 2015 to 2019, 174 of whom (34.8%) were considered having complex bifurcation lesions. Bifurcations involved the left main in 35.2% of cases. The full re-POT sequence was systematically performed in all cases. At 1 year, TLF was 2.0% (1.7% in complex vs. 2.1% in non-complex bifurcation; p = NS), and TLR was 1.6%, (1.1% vs. 1.8% respectively; p = NS). TVF and TVR rates were 3.2% and 2.8%. On multivariate analysis, only multivessel disease was predictive of TLF at 1 year (OR = 1.66 (1.09-2.53), p = 0.02). CONCLUSIONS In this large prospective all-comer registry, provisional stenting with re-POT technique appeared safe and effective at 1 year, without anatomical bifurcation restriction.

Abstract
BACKGROUND Optimal stent deployment in left main (LM) bifurcation is paramount, and incomplete stent apposition may cause major adverse cardiac events (MACE). Bench studies show that the proximal optimization technique (POT) provides the best stent apposition. AIMS We aimed to investigate the impact of POT on clinical outcomes in patients treated for unprotected LM (ULM) disease at our institution. METHODS We identified 162 patients who underwent percutaneous coronary intervention (PCI) for ULM coronary disease in the Cardio-FR database. Out of these, 99 (61%) had undergone POT, while 63 patients were treated without POT. The primary outcome was the bifurcation-oriented composite endpoint (BOCE) of cardiac death, target-bifurcation myocardial infarction and target-bifurcation revascularization at maximal follow-up. RESULTS Mean age was 76 years, and 69% presented with acute coronary syndrome. Mean follow-up was 2.25 years (822 days). The BOCE occurred in 43 (27%) of which 20 (20%) in the POT group and 23 (37%) in the no-POT group (p = 0.009). Cardiac death occurred in 15 (15%) patients in the POT- and 17 (27%) in no-POT group (p = 0.26). Target bifurcation revascularization occurred in 4 (4%) patients in the POT- and 6 (10%) patients in the no-POT group (p = 0.19). POT In the multivariate analysis, POT was the strongest parameter and was associated with BOCE, cardiac death, occurrence of any revascularization and all-cause mortality. CONCLUSION The POT improves clinical outcomes. These findings strongly support the systematic use of POT in patients undergoing ULM-PCI.

Impact of coronary bifurcation angle on stent malapposition in a randomized comparison between proximal optimization technique followed by side branch dilatation and kissing balloon inflation. IJC HEART & VASCULATURE 2023; 48:101265.

Abstract
Background The impact of coronary bifurcation angle (BA) on incomplete stent apposition (ISA) after crossover stenting followed by side branch (SB) intervention has not been established. Methods A total of 100 crossover stentings randomly treated with proximal optimization technique followed by short balloon dilation in the SB (POT-SBD group, 48 patients) and final kissing balloon technique (KBT group, 52 patients) were analyzed in the PROPOT trial. Major ISA with maximum distance > 400 μm and its location was determined using optical coherence tomography before SB intervention and at the final procedure. The BA was defined as the angle between the distal main vessel and SB. Optimal POT was determined when the difference in stent volume index between the proximal and distal bifurcation was greater than the median value (0.86 mm3/mm) before SB intervention. Result Major ISA was more frequently observed in the POT-SBD than in the KBT group (35% versus 17%, p < 0.05). In the POT-SBD group, worsening ISA after SBD was prominent at the distal bifurcation. The BA was an independent predictor of major ISA (odds ratio 1.04, 95% confidence interval 1.00-1.07, p < 0.05) with a cut-off value of 59.5° (p < 0.05). However, the cases treated with optimal POT in the short BA (<60°) indicated the lowest incidence of major ISA. In the KBT group, BA had no significant impact. Conclusion A wide BA has a potential risk for the occurrence of major ISA after POT followed by SBD in coronary bifurcation stenting.

Abstract
OBJECTIVE There is a lack of data regarding the long-term clinical efficacy of the kissing balloon inflation (KBI) after provisional stenting of coronary bifurcation lesions. The aim of this study was to analyze the impact of KBI on long-term clinical outcomes in patients undergoing provisional stenting for the coronary bifurcation lesions in a large real-world population. METHODS A total of 873 patients who underwent percutaneous coronary interventions (PCI) with provisional stenting and had clinical follow up were analyzed. Patients treated with 2-stent strategy were excluded. To reduce the effect of potential confounding factors in this observational study, propensity score matching was conducted. RESULTS KBI was performed in 325 patients (37.2%). The median follow-up duration was 37.3 months. Patients treated with KBI more often had a previous PCI (48.6% vs. 42.5% SMD = 0.123). Patients in non-kissing group had more complex coronary disease with higher prevalence of calcification (14.8% vs. 21.4% SMD = 0.172), thrombosis (2.8% vs. 5.8% SMD = 0.152) and longer side branch lesions (8.3% vs. 11.7% SMD = 0.113). There were no significant differences in the major adverse cardiac events including death, myocardial infarction, target lesion revascularization after KBI versus no KBI (15.4% vs. 15.7%, p = 0.28), in total cohort or in matched patients (17.1% vs. 15.8%, adjusted HR 1.01, 95% CI: 0.65-1.65, p = 0.95). The lack of effect of KBI on clinical outcomes was consistent across various subgroups including left main disease. CONCLUSION In this multicenter real-world registry, KBI did not improve long-term clinical outcomes in patients with coronary bifurcation lesions treated with provisional stenting technique.

Vascular healing after kissing balloon inflation: Nine-month 3D optical coherence tomography analysis in corelab. IJC HEART & VASCULATURE 2022; 40:101034. [PMID: 35495581 PMCID: PMC9052145 DOI: 10.1016/j.ijcha.2022.101034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2022] [Revised: 03/12/2022] [Accepted: 04/14/2022] [Indexed: 11/23/2022]
Abstract
Background The jailing strut configuration with link-free and distal guidewire recrossing (LFD) at the side branch orifice (SBO) reduces incomplete stent apposition (ISA) after kissing balloon technique (KBT) in crossover stenting of coronary bifurcation lesions (CBLs). However, data regarding vascular healing after KBT are lacking. We investigated vascular healing 9 months after crossover stenting followed by KBT with optical coherence tomography (OCT) guidance in a prospective multicenter registry. Methods Fifty-nine patients with CBLs (LFD, 35 patients; non-LFD, 24 patients) were studied. The jailing configuration of the SB and the wire-recrossing position, incidence of ISA and uncovered struts, and neointima unevenness score (NUS) in the main vessel (MV) after 9 months were determined by off-line 3D-OCT in the core laboratory. Results The ISA rate was significantly higher at the SB ostium and distal MV after KBT in the non-LFD group, compared to the LFD group. After 9 months, incidence of ISA (18.3 ± 18.2 vs. 6.0 ± 8.7%, p < 0.01) and uncovered struts (8.7 ± 9.9 vs. 4.7 ± 7.3 %, p = 0.08) were higher at the SB ostium with higher SB restenosis in the non-LFD group. In distal MV, NUS was significantly higher (3.1 ± 1.1 vs. 2.5 ± 0.6, p < 0.05). In true-CBLs, an increase in uncovered struts and ISA rate was prominent in the proximal MV and opposite SB. No differences were observed in the 9-month clinical outcomes. Conclusion Visualization of the wire recrossing point and the SB-jailing strut pattern by OCT plays an important role to optimize the KBT in CBL stenting, resulting in favorable mid-term vascular healing.

Abstract
OBJECTIVE We investigated the effect of proximal optimization technique (POT) on coronary bifurcation stent failure (BSF) in cross-over stenting by comparing with the kissing balloon technique (KBT) in a multicenter randomized PROPOT trial. BACKGROUND POT is recommended due to increased certainty for optimal stent expansion and side branch (SB) wiring. METHODS We randomized 120 patients treated with crossover stenting into the POT group, which was followed by SB dilation (SBD), and the KBT group. Finally, 52 and 57 patients were analyzed by optical coherence tomography before SBD and at the final procedure, respectively. Composite BSF was defined as a maximal malapposition distance of >400 μm, or malapposed and SB-jailed strut rates of >5.95% and >21.4%, respectively. RESULTS Composite BSF before SBD in the POT and KBT groups was observed in 29% and 26% of patients, respectively. In the POT group, differences in stent volumetric index between the proximal and distal bifurcation (odds ratio [OR] 60.35, 95% confidential interval [CI] 0.13-0.93, p = 0.036) and between the proximal bifurcation and bifurcation core (OR: 3.68, 95% CI: 1.01-13.40, p = 0.048) were identified as independent risk factors. Composite BSF at final in 27% and 32%, and unplanned additional procedures in 38% and 25% were observed, respectively. Composite BSF before SBD was a risk factor for the former (OR: 6.33, 95% CI: 1.10-36.50, p = 0.039) and the latter (OR: 6.43, 95% CI: 1.25-33.10, p = 0.026) in the POT group. CONCLUSION POT did not result in a favorable trend in BSF. Insufficient expansion of the bifurcation core after POT was associated with BSF.
