Abstract
Comparison of clinical outcomes of double kissing crush (DKC) and mini-crush (MC) techniques in patients with complex coronary bifurcation lesions is lacking. This study sought to determine the clinical results of DKC and MC stenting techniques in mid-term follow-up. This retrospective study included a total of 269 consecutive patients with complex bifurcation lesions who underwent percutaneous coronary intervention; 132 (49%) of them were treated with MC technique, whereas 137 (51%) treated with DKC technique. The primary end point was target lesion failure (TLF), defined as the combination of cardiac death, target vessel myocardial infarction, or clinically driven target lesion revascularization. This is the first study to compare the cardiovascular outcomes of DKC and MC stenting techniques in patients with complex bifurcation lesions. The SYNTAX scores were similar in both groups (23 [20 to 30] vs 23 [19 to 28], p = 0.631)]. The number of balloons (6.31 ± 1.80 vs 4.42 ± 0.87, p <0.001) and guidewires (3.55 ± 0.83 vs 2.86 ± 0.74, p <0.001) used, fluoroscopy time (21.55 ± 7.05 vs 16.66 ± 4.19 minutes, p <0.001), and procedure time (80.42 ± 27.95 vs 69.61 ± 18.97 minutes, p <0.001) were significantly higher in the DKC group. The rate of composite TLF was similar in complex bifurcation patients treated with MC than those treated with the DKC technique (14% vs 12%, p = 0.453). Moreover, both groups had similar rates in terms of cardiac death or all-cause death, target vessel-related myocardial infarction, clinically driven target lesion revascularization, and stent thrombosis. In conclusion, the present study showed that both techniques of bifurcation treatment met high angiographic success with low complication and similar TLF rates.

Abstract
BACKGROUND Controversy still exists regarding the optimal treatment of coronary bifurcation lesions. AIMS We aimed to analyse the evidence from randomised controlled trials (RCTs) to compare outcomes following different bifurcation stenting techniques. METHODS We systematically searched for RCTs comparing different techniques published up to July 2022. We then conducted a pairwise meta-analysis to compare outcomes between provisional stenting (PS) versus upfront 2-stent techniques. Moreover, we performed a network meta-analysis (NMA) to compare all strategies with each other. The primary endpoint was major adverse cardiac events (MACE). RESULTS Twenty-four RCTs (6,890 patients) analysed PS, T-stenting, double-kissing (DK)-crush, crush, or culotte stenting. The pairwise meta-analysis did not reveal a significant difference between the PS and 2-stent techniques. However, the prespecified sensitivity analysis, which included RCTs exclusively enrolling patients with true bifurcation lesions, showed a lower rate of MACE following 2-stent techniques, and meta-regression indicated that a longer side branch lesion was associated with a greater benefit from the 2-stent strategy, which was the most apparent in RCTs with a mean lesion length >11 mm. NMA revealed that DK-crush was associated with the lowest MACE rate (odds ratio 0.47, 95% confidence interval: 0.36-0.62; p<0.01; PS as a reference). CONCLUSIONS Overall, 2-stent techniques were not significantly better than PS in terms of clinical outcomes. However, the results of the sensitivity analysis suggested that there might be a benefit of a 2-stent approach in selected patients with true bifurcation lesions, especially in the case of long side branch lesions. An NMA revealed that DK-crush was associated with the lowest event rates when compared with other techniques.

Abstract
Interventional treatment of bifurcation lesions, especially true complex bifurcation lesions, continue to be a challenge for interventional cardiologists. A primary one stent strategy is always preferred for simple bifurcation lesions, whereas studies in recent years have shown that a two stent strategy may be advantageous for true bifurcations, i.e. those involving at least the distal main branch as well as the side branch. This seems to be even more pronounced when the lesion presents as complex, i.e., the side branch shows high-grade stenosis over longer stretches and the complete lesion fulfils certain criteria, e.g., severe calcification and a bifurcation angle < 45° or > 70°. According to the latest randomized trials and meta-analyses, the double kissing (DK) crush and double kissing mini-crush (DKMC) techniques in particular seem to be advantageous for these lesions; however, in recent years the established techniques have been continuously refined and further developed. The DK culotte technique and the nano-crush technique deserve special attention. Both techniques seem to further improve and simplify the existing underlying strategies; however, further studies to prove the superiority of these techniques over the established ones are still pending. Overall, the implementation of the available randomized study results, the further development of the techniques and also of the materials can continuously improve the outcome of the patients after interventional treatment of bifurcation lesions. This is also confirmed by the latest registry data, which for the first time could show equal event rates in patients after treatment of complex lesions compared to simple lesions in the clinical practice.

Abstract
The European Bifurcation Club (EBC) supports a continuous review of the field of coronary artery bifurcation interventions and aims to facilitate a scientific discussion and an exchange of ideas on the management of bifurcation disease. The recent focus of meetings and consensus statements has been on the technical issues in bifurcation stenting, recognising that the final result of a bifurcation procedure and the long-term outcome for our patients are strongly influenced by factors, including preprocedural strategy, stenting technique selection, performance of optimal procedural steps, the ability to identify and correct complications and finally, and most important, the overall performance of the operator. Continuous refinement of bifurcation stenting techniques and the promotion of education and training in bifurcation stenting techniques represent a major clinical need. Accordingly, the consensus from the latest EBC meeting in Brussels, October 2021, was to promote education and training in bifurcation stenting based on the EBC principle. Part II of this 16th EBC consensus document aims to provide a step-by-step overview of the pitfalls and technical troubleshooting during the implantation of the second stent either in the provisional stenting (PS) strategy or in upfront 2-stent techniques (e.g., 2-stent PS pathway and double kissing crush stenting). Finally, a detailed overview and discussion of the numerous modalities available to provide continuous education and technical training in bifurcation stenting techniques are discussed, with consideration of their future application in enhancing training and practice in coronary bifurcation lesion treatment.

Abstract
Background Bifurcation lesions account for 20% of all percutaneous coronary interventions and represent a complex subset which are associated with lower procedural success and higher rates of restenosis. The ideal bifurcation technique, however, remains elusive. Methods and Results Extensive search of the literature was performed to pull data from randomized clinical trials that met predetermined inclusion criteria. Conventional meta-analysis produced pooled relative risk (RR) and 95% CI of 2-stent technique versus provisional stent on prespecified outcomes. Both frequentist and Bayesian network meta-analyses were performed to compare bifurcation techniques. A total of 8318 patients were included from 29 randomized clinical trials. Conventional meta-analysis showed no significant differences in all-cause mortality, cardiac death, major adverse cardiac events, myocardial infarction, stent thrombosis, target lesion revascularization, and target vessel revascularization between 2-stent techniques and provisional stenting. Frequentist network meta-analysis revealed that double kissing crush was associated with lower cardiac death (RR, 0.57; 95% CI, 0.38-0.84), major adverse cardiac events (RR, 0.50; 95% CI, 0.39-0.64), myocardial infarction (RR, 0.60; 95% CI, 0.39-0.90), stent thrombosis (RR, 0.50; 95% CI, 0.28-0.88), target lesion revascularization, and target vessel revascularization when compared with provisional stenting. Double kissing crush was also superior to other 2-stent techniques, including T-stent or T and protrusion, dedicated bifurcation stent, and culotte. Conclusions Double kissing crush was associated with lower risk of cardiac death, major adverse cardiac events, myocardial infarction, stent thrombosis, target lesion revascularization, and target vessel revascularization compared with provisional stenting and was superior to other 2-stent techniques. Superiority of 2-stent strategy over provisional stenting was observed in subgroup meta-analysis stratified to side branch lesion length ≥10 mm.

Abstract
Coronary bifurcation lesions (CBLs) account for 15%-20% of all percutaneous coronary interventions. The complex nature of these lesions is responsible for poorer procedural, early and late outcomes. This complex lesion subset has received great attention in the interventional cardiac community, and multiple stenting techniques have been developed. Of these, the provisional stenting technique is most often the default strategy; however, the elective double stenting (EDS) technique is preferred in certain subsets of complex CBLs. The double kissing crush technique may be the preferred EDS technique because of its efficacy and safety in comparative trials; however, this technique consists of many steps and requires training. Many new methods have recently been added to the EDS techniques to provide better stent scaffolding and to reduce early and late adverse outcomes. Intravascular imaging is necessary to determine the interventional strategy and postinterventional results. This review discusses the basic concepts, contemporary percutaneous interventional technical approaches, new methods, and controversial treatment issues of CBLs.

Abstract
Percutaneous coronary interventions performed at coronary bifurcations yield high rates of stent thrombosis (ST). The aim of the present study was to investigate the predictors of ST in contemporary coronary bifurcation percutaneous coronary interventions. We retrospectively investigated the BIFURCAT (comBined Insights From the Unified RAIN and COBIS bifurcAtion regisTries) registry on coronary bifurcations to assess the incidence and predictors of definite ST, which were the study primary endpoints. Predictors of ST among patients on dual antiplatelet therapy (DAPT) were also examined. A total of 5330 patients were included. After a mean 2-years follow-up, 64 (1.2%) patients experienced ST. 42 (65.6%) ST patients were on DAPT. At multivariable analysis, age (HR 1.02, CI 1.01 to 1.05, p = 0,027), smoking status (HR 2.57, CI 1.49 to 4.44, p = 0.001), chronic kidney disease (HR 2.26, CI 1.24 to 4.12, p = 0.007) and a 2-stent strategy (HR 2.38, CI 1.37 to 4.14, p = 0.002) were independent predictors of ST, whereas intracoronary imaging (HR 0.42, CI 0.23 to 0.78, p = 0.006) and final kissing balloon (FKB) (HR 0.48, CI 0.29 to 0.82, p = 0.007) were protective against ST. Among patients on DAPT, smoking status and a 2-stent strategy significantly increased the risk of ST, while intracoronary imaging and FKB reduced the risk. In conclusion, age, smoking status, chronic kidney disease and a 2-stent strategy were significant predictors of ST, whereas intracoronary imaging use and FKB had a protective effect. Only smoking status and a 2-stent strategy significantly predicted ST in DAPT subgroup, while intracoronary imaging and FKB had a protective role.

Abstract
BACKGROUND The jailed balloon technique is widely used for coronary bifurcation lesions, but a residual risk of SB occlusion remains, necessitating SB rewiring and further interventions, including balloon inflation or stenting, which may result in failure and SB loss. This study introduced a novel modified technique of small side branch (SB) protection, namely, double kissing inflation outside the stent (DKo) technique, for coronary bifurcations without the need for SB rewiring. METHODS We performed the DKo technique in consecutive patients in our center from 1/2019 to 12/2019. The procedure was as follows. We inserted a guide wire into both branches followed by proper preparation. The SB balloon was simultaneously inflated with main vessel (MV) stenting. The SB balloon remained in situ until it was kissing inflated with postdilation of the bifurcation core, which is different from traditional strategies. The proximal optimization technique was performed with a short noncompliant balloon strictly not exceeding the bifurcation. Rates of SB loss and in-hospital outcomes were evaluated. RESULTS The technique was successfully performed in all 117 enrolled patients without any rewiring or SB loss. The mean lesion lengths of the MV and SB were 38.3 ± 19.9 mm and 11.7 ± 7.1 mm, respectively. On average, 1.5 ± 0.6 stents were used per patient, while the mean pressure of the SB balloon was 7.4 ± 3.1 atm. DKo achieved excellent procedural success in the proximal and distal MVs: increased minimal lumen diameter (0.64 ± 0.58 mm to 3.05 ± 0.38 mm, p < 0.001; 0.57 ± 0.63 mm to 2.67 ± 0.35 mm, p < 0.001) and low residual stenosis (11.4 ± 3.4%; 7.2 ± 4.6%). DKo secured the patency of the SB without any rewiring and improved the SB stenosis with minimal lumen diameter (0.59 ± 0.48 mm to 1.20 ± 0.42 mm, p < 0.001) and stenosis (71.9 ± 19.4% to 42.2 ± 14.0%, p < 0.001). No MACE was noted in the hospital. CONCLUSIONS DKo for bifurcation lesions was shown to be acceptable with high procedural success and excellent SB protection.

Abstract
OBJECTIVES We conducted a systematic review and network meta-analysis of available randomized clinical trials (RCTs) to compare cardiovascular outcomes involving stenting techniques in coronary bifurcation lesions. BACKGROUND Although provisional stenting of the main branch and balloon angioplasty of the side branch is considered the standard approach, the use of two stents is often pursued with a wide variety of bifurcation stenting techniques available. METHODS We searched PubMed, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), and Clinicaltrials.gov from inception to December 2018. We performed a frequentist network meta-analysis to estimate relative risks (RR) of death, major adverse cardiovascular events (MACE), target vessel revascularization (TVR), target lesion revascularization (TLR), and stent thrombosis (ST) among different two stent bifurcation techniques. RESULTS We identified 14 studies, yielding data on 4,285 patients. Double Kissing (DK) Crush and Mini-crush were associated with significant reductions in MACE, TVR, and TLR when compared with the Provisional stenting (RR 0.31-0.55 [all p < .01] and RR 0.42-0.45 [all p < .02], respectively) and with the remaining bifurcation techniques (RR 0.44-0.55 [all p < .05] for DK Crush and RR 0.37-0.45 [all p < .05] for Mini-crush). In addition, Culotte and Crush were associated with an increased risk for ST compared to Provisional stenting (RR 3.25-4.27 [both p < .05]) and to DK crush (RR 3.02-3.99 [both p < .05]). CONCLUSIONS DK crush and mini-crush were found to be associated with fewer events and complications compared to the other techniques reviewed, including the Provisional approach. Further, Culotte and Crush were associated with an increased risk of stent thrombosis when compared to the Provisional approach.

Abstract
Background The present study is a prospective observational single arm clinical investigation, with parallel bench test interrogation, aimed at investigating the technical feasibility, safety and clinical outcomes with the cone flare crush modified-T (CFCT) bifurcation stenting technique. Bifurcation percutaneous coronary intervention (PCI) remains an area of ongoing procedural evolution. More widely applicable and reproducible techniques are required. Methods From April 2018 until March 2019, 20 consecutive patients underwent bifurcation PCI using the CFCT technique with a Pt-Cr everolimus drug-eluting stent with a bioresorbable polymer. Exercise stress echocardiography was performed at 12-month follow-up. The primary outcome was a composite of cardiac related mortality, myocardial infarction, target lesion/vessel revascularization and stroke. Safety secondary endpoints included bleeding, all-cause mortality and stent thrombosis. Results All patients underwent a successful CFCT bifurcation procedure with no complications to 30-day follow-up. One patient met the primary endpoint requiring target lesion revascularization at 9 months for stable angina. There were no other primary or secondary outcome events in the cohort. There were no strokes, deaths, stent thrombosis or myocardial infarction during the follow-up period. The mean CCS score improved from 2.25 to 0.25 (p < 0.0001). Optical coherence tomography (OCT) and bench test findings indicated optimal side branch ostial coverage and minimal redundant strut material crowding the neo-carina. Conclusions The CFCT technique appears to be a safe, efficacious and feasible strategy for managing coronary artery bifurcation disease. Expanded and randomized datasets with longer term follow-up are required to further explore confirm this feasibility data. (ANZCTR ID: ACTRN12618001145291).

Abstract
PURPOSE We sought to evaluate angiographic outcomes in ostial and distal LM lesions. METHODS 176 patients with LM disease undergoing PCI were retrospectively included in this study. 9 months of angiographic and 12 months of clinical follow-up was obtained. Quantitative coronary analysis (QCA) was performed for all lesions, using an 11-segment model. Clinical endpoint measure was a composite endpoint of cardiac death, myocardial infarction and target lesion revascularization (TLR). RESULTS During 12 months follow up after successful PCI, the composite endpoint occurred more frequently in distal LM bifurcation lesions mainly driven by elevated TLR rates (14.1% in distal LM disease vs. 5.6% in ostial/midshaft LM disease, P = 0.20). Concordantly angiographic binary restenosis (8.2% compared to 0.0%) and late lumen loss (LLL, 0.42 ± 0.97 vs. 0.28 ± 0.34 mm) were increased in distal LM bifurcation lesions compared to ostial LM lesions. In distal lesions highest values for LLL were observed in segments adjacent to the bifurcation (0.37 ± 1.13 mm and 0.37 ± 0.73 mm). On cox proportional regression analysis the angiographic parameter LLL in a bifurcation segment (P = 0.03, HR 1.68 [1.1-2.7]) as well as presence of diabetes mellitus as a clinical parameter (P = 0.046, HR 2.77 [1.0-7.5]) were independent correlates for occurrence of MACE in distal LM bifurcations lesions. CONCLUSION PCI of ostial LM in accomplished with low LLL (0.28 ± 0.34 mm) and binary restenosis rates. In distal left main lesions highest rates for LLL and binary restenosis were observed in segments nearest to the bifurcation and rather focused on the main vessel (0.42 ± 0.97 mm).

Abstract
Coronary artery bypass surgery has been the accepted treatment for left main coronary artery disease for over 50 years. Balloon angioplasty was later used then abandoned because of deaths likely due to restenosis or thrombotic occlusion. However, rapid innovations in drug-eluting stent designs leading to more biocompatible thin strut platforms with optimal drug elution profiles and further advances in modern pharmacotherapy involving potent P2Y12 inhibitors combined with utilization of intracoronary imaging and physiologic assessment for procedural planning and optimization have transformed percutaneous interventions into successful alternatives to coronary artery bypass graft surgery (CABG) in selected LM anatomic territories. Herein, we provide an evidence-based practical guide on how to approach and perform LM percutaneous interventions (PCI).

Abstract
PURPOSE OF REVIEW This paper provides a synopsis of the best evidence to guide bifurcation percutaneous coronary intervention (PCI), with a focus on recent studies. This is with the aim of guiding the interventional cardiologist in choosing the best, evidence-based technique, to treat commonly encountered coronary bifurcations. RECENT FINDINGS Current evidence supports the use of provisional stenting for most anatomically suitable bifurcation lesions. Newer techniques for side branch protection in provisional stenting have been developed. When a two-stent strategy is required, use of a double-kissing crush technique is favoured, particularly in left main bifurcations. For bifurcation PCI, as in all complex procedures, intravascular imaging plays a key adjunctive role in improving procedural success. PCI for coronary bifurcation lesions is an ever-growing field with significant advancements in techniques and technology.
