RESUMO
BACKGROUND: The impact of intracoronary imaging on outcomes, after provisional versus dual-stenting for bifurcation left main (LM) lesions, is unknown. OBJECTIVES: We investigated the effect of intracoronary imaging in the EBC MAIN trial (European Bifurcation Club LM Coronary Stent study). METHODS: Four hundred and sixty-seven patients were randomized to dual-stenting or a stepwise provisional strategy. Four hundred and fifty-five patients were included. Intravascular ultrasound (IVUS) or optical coherence tomography (OCT) was undertaken at the operator's discretion. The primary endpoint was death, myocardial infarction or target vessel revascularization at 1-year. RESULTS: Intracoronary imaging was undertaken in 179 patients (39%; IVUS = 151, OCT = 28). As a result of IVUS findings, operators reintervened in 42 procedures. The primary outcome did not differ with intracoronary imaging versus angiographic-guidance (17% vs. 16%; odds ratio [OR]: 0.92 (95% confidence interval [CI]: 0.51-1.63) p = 0.767), nor for reintervention based on IVUS versus none (14% vs. 16%; OR: 0.88 [95% CI: 0.32-2.43] p = 0.803), adjusted for syntax score, lesion calcification and ischemic symptoms. With angiographic-guidance, primary outcome events were more frequent with dual versus provisional stenting (21% vs. 10%; adjusted OR: 2.11 [95% CI: 1.04-4.30] p = 0.039). With intracoronary imaging, there were numerically fewer primary outcome events with dual versus provisional stenting (13% vs. 21%; adjusted OR: 0.56 [95% CI: 0.22-1.46] p = 0.220). CONCLUSIONS: In EBC MAIN, the primary outcome did not differ with intracoronary imaging versus none. However, in patients with angiographic-guidance, outcomes were worse with a dual-stent than provisional strategy When intracoronary imaging was used, there was a trend toward better outcomes with the dual-stent than provisional strategy.

BACKGROUND: Techniques for provisional and dual-stent left main bifurcation stenting require optimization. AIM: To identify technical variables influencing procedural outcomes and periprocedural myocardial infarction following left main bifurcation intervention. METHODS: Procedural and outcome data were analyzed in 438 patients from the per-protocol cohort of the European Bifurcation Club Left Main Trial (EBC MAIN). These patients were randomized to the provisional strategy or a compatible dual-stent extension (T, T-and-protrude, or culotte). RESULTS: Mean age was 71 years and 37.4% presented with an acute coronary syndrome. Transient reduction of side vessel thrombolysis in myocardial infarction flow occurred after initial stent placement in 5% of procedures but was not associated with periprocedural myocardial infarction. Failure to rewire a jailed vessel during any strategy was more common when jailed wires were not used (9.5% vs. 2.5%, odds ratio [OR]: 6.4, p = 0.002). In the provisional cohort, the use of the proximal optimization technique was associated with less subsequent side vessel intervention (23.3% vs. 41.9%, OR: 0.4, p = 0.048). Side vessel stenting was predominantly required for dissection, which occurred more often following side vessel preparation (15.3% vs. 4.4%, OR: 3.1, p = 0.040). Exclusive use of noncompliant balloons for kissing balloon inflation was associated with reduced need for side vessel intervention in provisional cases (20.5% vs. 38.5%, OR: 0.4, p = 0.013), and a reduced risk of periprocedural myocardial infarction across all strategies (2.9% vs. 7.7%, OR: 0.2, p = 0.020). CONCLUSION: When performing provisional or compatible dual-stent left main bifurcation intervention, jailed wire use is associated with successful jailed vessel rewiring. Side vessel preparation in provisional patients is linked to increased side vessel dissection requiring stenting. Use of the proximal optimization technique may reduce the need for additional side vessel intervention, and noncompliant balloon use for kissing balloon inflation is associated with a reduction in both side vessel stenting and periprocedural myocardial infarction.

BACKGROUND: Patients with non-left-main coronary bifurcation lesions are usually best treated with a stepwise provisional approach. However, patients with true left main stem bifurcation lesions have been shown in one dedicated randomized study to benefit from systematic dual stent implantation. METHODS AND RESULTS: Four hundred and sixty-seven patients with true left main stem bifurcation lesions requiring intervention were recruited to the EBC MAIN study in 11 European countries. Patients were aged 71 ± 10 years; 77% were male. Patients were randomly allocated to a stepwise layered provisional strategy (n = 230) or a systematic dual stent approach (n = 237). The primary endpoint (a composite of death, myocardial infarction, and target lesion revascularization at 12 months) occurred in 14.7% of the stepwise provisional group vs. 17.7% of the systematic dual stent group (hazard ratio 0.8, 95% confidence interval 0.5-1.3; P = 0.34). Secondary endpoints were death (3.0% vs. 4.2%, P = 0.48), myocardial infarction (10.0% vs. 10.1%, P = 0.91), target lesion revascularization (6.1% vs. 9.3%, P = 0.16), and stent thrombosis (1.7% vs. 1.3%, P = 0.90), respectively. Procedure time, X-ray dose and consumables favoured the stepwise provisional approach. Symptomatic improvement was excellent and equal in each group. CONCLUSIONS: Among patients with true bifurcation left main stem stenosis requiring intervention, fewer major adverse cardiac events occurred with a stepwise layered provisional approach than with planned dual stenting, although the difference was not statistically significant. The stepwise provisional strategy should remain the default for distal left main stem bifurcation intervention. STUDY REGISTRATION: http://clinicaltrials.gov NCT02497014.

BACKGROUND: No randomized study powered to compare balloon expandable (BE) with self expanding (SE) transcatheter heart valves (THVs) on individual end points after transcatheter aortic valve replacement has been conducted to date. METHODS: From January 2013 to December 2015, the FRANCE-TAVI nationwide registry (Registry of Aortic Valve Bioprostheses Established by Catheter) included 12 141 patients undergoing BE-THV (Edwards, n=8038) or SE-THV (Medtronic, n=4103) for treatment of native aortic stenosis. Long term mortality status was available in all patients (median 20 months; interquartile range, 14 to 30). Patients treated with BE-THV (n=3910) were successfully matched 1:1 with 3910 patients treated with SE-THV by using propensity score (25 clinical, anatomical, and procedural variables) and by date of the procedure (within 3 months). The first coprimary outcome was ≥ moderate occurrence of paravalvular regurgitation or in-hospital mortality, or both. The second coprimary outcome was 2-year all-cause mortality. RESULTS: In propensity-matched analyses, the incidence of the first coprimary outcome was higher with SE-THV (19.8%) compared with BE-THV (11.9%; relative risk, 1.68 [95% CI, 1.46-1.91]; P<0.0001). Each component of the outcome was also higher in patients receiving SE-THV: ≥ moderate paravalvular regurgitation (15.5% versus 8.3%; relative risk, 1.90 [95% CI, 1.63-2.22]; P<0.0001) and in hospital mortality (5.6% versus 4.2%; relative risk, 1.34 [95% CI, 1.07-1.66]; P=0.01). During follow up, all cause mortality occurred in 899 patients treated with SE-THV (2-year mortality, 29.8%) and in 801 patients treated with BE-THV (2-year mortality, 26.6%; hazard ratio, 1.17 [95% CI, 1.06-1.29]; P=0.003). Similar results were found using inverse probability of treatment weighting using propensity score analysis. CONCLUSION: The present study suggests that use of SE-THV was associated with a higher risk of paravalvular regurgitation and higher in-hospital and 2-year mortality compared with use of BE-THV. These data strongly support the need for a randomized trial sufficiently powered to compare the latest generation of SE-THV and BE-THV. CLINICAL TRIAL REGISTRATION: https://www.clinicaltrials.gov.

The 2023 European Bifurcation Club (EBC) meeting took place in Warsaw in October, and the latest evidence for the use of intravascular ultrasound (IVUS) and optical coherence tomography (OCT) to optimise percutaneous coronary interventions (PCI) on coronary bifurcation lesions (CBLs) was a major focus. The topic generated deep discussions and general appraisal on the potential benefits of IVUS and OCT in PCI procedures. Nevertheless, despite an increasing recognition of IVUS and OCT capabilities and their recognised central role for guidance in complex CBL and left main PCI, it is expected that angiography will continue to be the primary guidance modality for CBL PCI, principally due to educational and economic barriers. Mindful of the restricted access/adoption of intracoronary imaging for CBL PCI, the EBC board decided to review and describe a series of tips and tricks which can help to optimise angiography-guided PCI for CBLs. The identified key points for achieving an optimal angiography-guided PCI include a thorough analysis of pre-PCI images (computed tomography angiography, multiple angiographic views, quantitative coronary angiography vessel estimation), a systematic application of the technical steps suggested for a given selected technique, an intraprocedural or post-PCI use of stent enhancement and a low threshold for bailout use of intravascular imaging.

Background: Left ventricular outflow track (LVOT) obstruction (LVOTO) is a severe complication of transcatheter mitral valve replacement (TMVR) procedures, with an uncertain prognosis and only few strategies available to prevent its occurrence. TMVR is thus contraindicated in some patients because of a high risk of LVOTO onset. We demonstrate how LVOTO can be managed with a balloon inflation in the LVOT and a D-shaped deformation of the bioprosthetic valve. Case summary: A 64-year-old female presented with acute pulmonary oedema 2 weeks following aortic valve replacement and aorto-coronary bypass surgeries. A concomitant mitral stenosis, secondary to significant calcifications of the mitral annulus, was not treated during the procedure. After surgery, the mitral valvulopathy caused an acute heart failure and TMVR was performed by the heart team. The procedure was complicated by a cardiac arrest secondary to the onset of LVOTO which was managed by a balloon inflation in the LVOT and an alcohol septal ablation. Two-year follow-up shows a favourable outcome of the patient and good function of the prosthetic valve despite its deformation. Discussion: This case highlights the successful management of a LVOTO following valve-in-mitral annular calcification TMVR by balloon inflation in the LVOT. It is strongly recommended to place a 'rescue' guidewire in transaortic position during TMVR in order to manage the potential onset of acute LVOTO.
RESUMO
Provisional stenting has become the default technique for the treatment of most coronary bifurcation lesions. However, the side branch (SB) can become compromised after main vessel (MV) stenting and restoring SB patency can be difficult in challenging anatomies. Angiographic and intracoronary imaging criteria can predict the risk of side branch closure and may encourage use of side branch protection strategies. These protective approaches provide strategies to avoid SB closure or overcome compromise following MV stenting, minimising periprocedural injury. In this article, we analyse the strategies of SB preservation discussed and developed during the most recent European Bifurcation Club (EBC) meetings.

The Bifurcation Academic Research Consortium (Bif-ARC) project originated from the need to overcome the paucity of standardization and comparability between studies involving bifurcation coronary lesions. This document is the result of a collaborative effort between academic research organizations and the most renowned interventional cardiology societies focused on bifurcation lesions in Europe, the United States, and Asia. This consensus provides standardized definitions for bifurcation lesions; the criteria to judge the side branch relevance; the procedural, mechanistic, and clinical endpoints for every type of bifurcation study; and the follow-up methods. Considering the complexity of bifurcation lesions and their evaluation, detailed instructions and technical aspects for site and core laboratory analysis of bifurcation lesions are also reported. The recommendations included within this consensus will facilitate pooled analyses and the effective comparison of data in the future, improving the clinical relevance of trials in bifurcation lesions, and the quality of care in this subset of patients.

BACKGROUND: As assessment of SYNTAX score is made by visual estimate of coronary angiography, discrepancies between evaluations by different observers and the impact of observer experience have not yet been evaluated. METHODS: Using the data of 166 patients with unprotected left main lesions treated with the second generation everolimus-eluting stent, we sought to analyze SYNTAX score assessment provided by one junior and two independent senior observers and to assess the impact of the quality of angiographies on the reproducibility of SYNTAX score determination. Intra-observer variability was assessed by a senior observer by analyzing 50 sets of angiograms after an interval of at least 6 weeks. RESULTS: The weighted kappa value for the inter-observer reproducibility of SYNTAX score classified as tertiles, according to SYNTAX trial, was 0.71 and the intra-observer weighted kappa value was 0.79. When compared with junior's measurements, SYNTAX score assessed by senior investigators was 0.46 and 0.50. Changes in SYNTAX score classification were arbitrarily responsible for changes in weighted kappa values. Angiograms showing the higher rates of discrepancies between observers were of lower quality, when compared with random angiograms. SYNTAX score was closely correlated to 1-year incidence of major adverse cerebro- and cardiovascular events for both junior and senior readers. CONCLUSIONS: SYNTAX score was slightly underestimated by junior reader, when compared with experienced operators. Inter- and intra-observer reproducibility of experienced operators was very acceptable. SYNTAX score evaluation was clearly related to the quality of angiograms. SYNTAX score was correlated to 1-year incidence of major cardiac and cerebrovascular events (MACCE) in all readers.

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.

The 15th European Bifurcation Club (EBC) meeting was held in Barcelona in October 2019. It facilitated a renewed consensus on coronary bifurcation lesions (CBL) and unprotected left main (LM) percutaneous interventions. Bifurcation stenting techniques continue to be refined, developed and tested. It remains evident that a provisional approach with optional side branch treatment utilising T, T and small protrusion (TAP) or culotte continues to provide flexible options for the majority of CBL patients. Debate persists regarding the optimal treatment of side branches, including assessment of clinical significance and thresholds for bail-out treatment. In more complex CBL, especially those involving the LM, adoption of dedicated two-stent techniques should be considered. Operators using such techniques have to be fully familiar with their procedural steps and should acknowledge associated limitations and challenges. When using two-stent techniques, failure to perform a final kissing inflation is regarded as a technical failure, since it may jeopardise clinical outcome. The development of novel technical tools and drug regimens deserves attention. In particular, intracoronary imaging, bifurcation simulation, drug-eluting balloon technology and tailored antiplatelet therapy have been identified as promising tools to enhance clinical outcomes. In conclusion, the evolution of a broad spectrum of bifurcation PCI components has resulted from studies extending from bench testing to randomised controlled trials. However, further advances are still needed to achieve the ambitious goal of optimising the clinical outcomes for every patient undergoing PCI on a CBL.

BACKGROUND: Cardiac surgery is the reference treatment for patients with left main (LM) disease, although percutaneous coronary intervention with drug-eluting stents is emerging as a possible alternative. The objective of this registry was to evaluate the 2-year outcome of elective percutaneous coronary intervention for unprotected LM disease with paclitaxel-eluting stents. METHODS AND RESULTS: A total of 291 patients were prospectively included from 4 centers. Acute myocardial infarction and cardiogenic shock were the only exclusion criteria. Patients were 69+/-11 years old, 29% were diabetic, and 25% had 3-vessel disease. For distal LM lesions (78%), the provisional side-branch T-stenting approach was used in 92% of cases and final kissing balloon inflation in 97%. Angiographic success was obtained in 99.7% of cases. At 2-year follow-up, the total cardiac death rate was 5.4% (1 EuroSCORE point was associated with a 15% [95% confidence interval 2.9% to 28.2%, P=0.013] higher risk of cardiac death), target-lesion revascularization was 8.7%, and incidence of Q-wave or non-Q-wave myocardial infarction was 0.9% and 3.1%, respectively. The combined end point occurred in 15.8% of cases and stroke in 0.7%. The incidence of definite and probable LM stent thrombosis was 0.7%, whereas the incidence of any stent thrombosis was 3.8%, with a higher risk in patients with side-branch stenting in the presence of LM bifurcation lesions (hazard ratio 9.6, 95% confidence interval 1.2 to 77.7, P=0.035). CONCLUSIONS: Unprotected LM stenting with paclitaxel-eluting stents, with a strategy of provisional side-branch T-stenting for distal lesions, provides excellent acute angiographic results and good mid-term clinical outcomes, with a 15.8% rate of major adverse cardiac events at 2-year follow-up.

BACKGROUND: Coronary artery disease and aortic stenosis often coexist. Transcatheter aortic valve implantation (TAVI) has emerged as a valid therapeutic option for younger, lower-risk patients who may eventually require coronary artery disease treatment. Thus, post-TAVI coronary access (CA) and percutaneous coronary intervention are expected to increase. The purpose of this study was to retrospectively evaluate patients who were enrolled in the SOURCE 3 (SAPIEN 3 Aortic Bioprosthesis European Outcome) European registry for treatment with the balloon-expandable SAPIEN 3 transcatheter heart valve and underwent CA with or without percutaneous coronary intervention after TAVI. METHODS: Baseline characteristics and clinical outcomes of patients with or without CA up to 3 years after TAVI were compared. A Kaplan-Meier estimate with a univariate model determined the impact of CA on cardiac mortality. RESULTS: Of 1936 TAVI patients (mean age 81.6 years, 52% male), 68 (3.5%) had CA within 3 years (mean 441±332 days) after TAVI. At baseline, the logistic EuroSCORE was similar (20.2% versus 18.3%, P=0.2, CA and non-CA groups, respectively). Higher rates of coronary artery disease (76.5% versus 50.6%, P<0.001), myocardial infarction (20.6% versus 11.5%, P=0.03) and previous coronary artery bypass graft (22.1% versus 11.0%, P=0.01) were present in the CA group. In 100% of patients, CA was successfully achieved. The clinical success of percutaneous coronary intervention was 97.9%. Cardiovascular mortality was numerically higher in patients with CA than in those without CA. CONCLUSIONS: In the large SOURCE 3 European registry, CA was needed at 3-year follow-up after TAVI with a balloon-expandable valve in 3.5% of patients and was successful in all patients. The clinical success of percutaneous coronary intervention was 97.9%. Registration: URL: https://www.clinicaltrials.gov. Unique identifier: NCT02698956.

The European Bifurcation Club recommends an approach to a bifurcation stenosis which involves careful assessment, planning and a sequential provisional approach. In the minority of lesions where two stents are required, careful deployment and optimal expansion are essential to achieve a long-term result.

Coronary artery bifurcation lesions comprise approximately 15-20% of all percutaneous coronary interventions (PCI) and constitute a complex lesion subgroup. Intravascular optical coherence tomography (OCT) is a promising adjunctive tool for guiding coronary bifurcation with its unrivalled high resolution. Compared to angiography, intravascular OCT has a clear advantage in that it depicts ostial lesion(s) in bifurcation without the misleading two-dimensional appearance of conventional angiography such as overlap and foreshortening. In addition, OCT has the ability to reconstruct a bifurcation in three dimensions and to assess the side branch ostium from 3D reconstruction of the main vessel pullback, which can be applied to ensure the optimal recrossing position of the wire after main vessel stenting. Recently, online co-registration of OCT and angiography became widely available, helping the operator to position a stent in precise landing zones, reducing the risk of geographic miss. Despite these technological advances, the currently available clinical data are based mainly on observational studies with a small number of patients; there is little evidence from randomised trials. The joint working group of the European Bifurcation Club and the Japanese Bifurcation Club reviewed all the available literature regarding OCT use in bifurcation lesions and here provides recommendations on OCT guiding of coronary interventions in bifurcation lesions.

BACKGROUND: Percutaneous coronary intervention (PCI) of coronary bifurcation lesions remains a subject of debate. Many studies have been published in this setting. They are often small scale and display methodological flaws and other shortcomings such as inaccurate designation of lesions, heterogeneity, and inadequate description of techniques implemented. METHODS: The aim is to propose a consensus established by the European Bifurcation Club (EBC), on the definition and classification of bifurcation lesions and treatments implemented with the purpose of allowing comparisons between techniques in various anatomical and clinical settings. RESULTS: A bifurcation lesion is a coronary artery narrowing occurring adjacent to, and/or involving, the origin of a significant side branch. The simple lesion classification proposed by Medina has been adopted. To analyze the outcomes of different techniques by intention to treat, it is necessary to clearly define which vessel is the distal main branch and which is (are) the side branche(s) and give each branch a distinct name. Each segment of the bifurcation has been named following the same pattern as the Medina classification. The classification of the techniques (MADS: Main, Across, Distal, Side) is based on the manner in which the first stent has been implanted. A visual presentation of PCI techniques and devices used should allow the development of a software describing quickly and accurately the procedure performed. CONCLUSION: The EBC proposes a new classification of bifurcation lesions and their treatments to permit accurate comparisons of well described techniques in homogeneous lesion groups.

The European Bifurcation Club (EBC) was initiated in 2004 to support a continuous overview 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 EBC hosts an annual, two-day compact meeting, dedicated to bifurcations, which brings together physicians, pathologists, engineers, biologists, physicists, mathematicians, epidemiologists and statisticians for detailed discussions. Every meeting is finalised with a consensus statement that reflects the unique opportunity of combining the opinion of interventional cardiologists with the opinion of a large variety of other scientists on bifurcation management. A series of consensus sessions dedicated to specific topics, to strengthen the consensus debates and focus the discussions, was introduced at this year's meeting. The sessions comprise an intensive overview of the present literature, a pro and con debate and a voting system, to guide the consensus-building process. The present document represents the summary of the up-to-date EBC consensus and recommendations from the 12th annual EBC meeting in 2016 in Rotterdam.

The 2017 European Bifurcation Club (EBC) meeting was held in Porto (Portugal) and allowed a multidisciplinary international faculty to review and discuss the latest data collected in the field of coronary bifurcation interventions. In particular, the topic of percutaneous coronary intervention (PCI) on left main coronary artery (LM) disease was highlighted as a contemporary priority. Herein, we summarise the key LM anatomy features, the diagnostic modalities and available data that are relevant for a patient's procedural management. Since the clinical outcomes of patients undergoing PCI on LM disease may depend on both PCI team organisation and PCI performance, the optimal catheterisation laboratory set-up and the rationales for device and technique selection are critically reviewed. The best lesion preparation modalities, the different DES implantation technique choices and the strategies to be considered during PCI on unprotected LM for optimal PCI results are reviewed step by step.
