State-of-the-art percutaneous coronary intervention for left main coronary artery disease in Japan. Cardiovasc Interv Ther 2024; 39:386-402. [PMID: 39078544 DOI: 10.1007/s12928-024-01030-4] [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: 07/04/2024] [Accepted: 07/08/2024] [Indexed: 07/31/2024]
Abstract
Percutaneous coronary intervention for left main coronary artery disease (LM-PCI) represents a high-risk yet life-saving procedure that has evolved significantly over the years. This review outlines the current state-of-the-art practices for LM-PCI in Japan in detail, emphasizing the integration of coronary physiology and intracoronary imaging alongside with evidence-based standardized technique using latest drug-eluting stents. These advancements enable precise lesion assessment, stent sizing, and optimal deployment, thereby enhancing procedural safety and efficacy. Despite discrepancies between current guidelines favoring coronary artery bypass grafting and real-world practice trends towards increased LM-PCI adoption, particularly in elderly populations with multiple comorbidities, careful patient selection and procedural planning are critical. Future perspectives include further refining LM-PCI through conducting randomized controlled trials integrating advanced techniques and addressing the issue of ostial left circumflex lesions and nationwide standardization of medical care for LM disease.

Can J Cardiol 2024; 40:1619-1631. [PMID: 38360149 DOI: 10.1016/j.cjca.2024.01.040] [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: 05/15/2023] [Revised: 01/11/2024] [Accepted: 01/19/2024] [Indexed: 02/17/2024] Open
Abstract
BACKGROUND The risk of side-branch (SB) occlusion is pivotal for decision making of stenting strategies during unprotected left main (LM) bifurcation percutaneous coronary intervention (PCI). Accordingly, this study aimed to develop a scoring system for predicting SB occlusion during unprotected LM bifurcation PCI. METHODS A total of 855 consecutive patients undergoing unprotected LM bifurcation PCI with provisional strategy at Fuwai Hospital from January 2014 to December 2016 were recruited. A prediction model was selected by means of all-subsets logistic regression, and a multivariable risk score (Left Main Visual Estimation for Risk Prediction of Side Branch Occlusion in Coronary Bifurcation Intervention [LM V-RESOLVE]) was then established with incremental weights attributed to each component variable based on its estimate coefficients. SB occlusion was defined as any decrease in Thrombolysis in Myocardial Infarction (TIMI) flow grade or absence of flow in SB after main vessel (MV) stenting. RESULTS SB occlusion occurred in 19 LM bifurcation lesions (2.22%). In multivariable model, 3 variables, including MV/SB diameter ratio, MV plaque ipsilateral to SB, and baseline diameter stenosis of SB, were independent predictors for SB occlusion (model C-statistic 0.829, 95% confidence interval [CI] 0.735-0.923, with good calibration). The risk score had a C-statistics of 0.830 (95% CI 0.738-0.923) with good calibration. Satisfactory discriminative ability of the risk score was also preserved in external validation (C-statistic 0.794, 95% CI 0.691-0.896). CONCLUSIONS The LM bifurcation-specific novel scoring system, LM V-RESOLVE, based on 3 simple baseline angiographic findings, could help to rapidly discriminate lesions at risk of SB occlusion during LM bifurcation PCI.

Comparing the clinical outcomes of single vs. systematic dual stenting strategies for unprotected left main bifurcation lesion: a systematic review and meta-analysis. Front Cardiovasc Med 2023; 10:1145412.

Abstract
INTRODUCTION The optimal percutaneous coronary intervention (PCI) strategy for coronary left main (LM) bifurcation lesions remains controversial. This meta-analysis compared the medium and long-term follow-up clinical outcomes of single vs. systematic dual stenting strategies of LM bifurcation lesions. METHODS We systematically identified studies published within 5 years comparing single vs. systematic double stenting strategies for LM bifurcation lesions. The primary endpoint was medium-term (1 year) and long-term (at least 3 years) all-cause death. Secondary outcomes included major adverse cardiovascular events (MACEs), target lesion revascularization (TLR), overall occurrence of stent thrombosis (ST), cardiovascular (CV) mortality, and myocardial infarction (MI). RESULTS Two randomized controlled trials and nine observational studies with 7,318 patients were included in this meta-analysis. In terms of the medium-term follow-up clinical outcomes, our pooled analysis showed that use of the systematic dual stenting strategy was associated with a lower ST risk (odds ratio [OR] = 0.43, 95% confidence interval [CI]: 0.20-0.89, P = 0.02) and cardiac death risk (OR = 0.43, 95% CI: 0.21-0.89, P = 0.02) compared to the single stenting strategy; there was no significant difference between the two strategies regarding rates of all-cause death, MACE, TLR, and MI. Patients with long-term follow-up showed comparable observed clinical outcomes between the two strategies. Most importantly, for patients with true LM bifurcation, the risk of all-cause death, ST, and CV mortality following the systematic dual stenting strategy was significantly lower than the single stenting strategy. CONCLUSIONS For patients with LM bifurcation lesions, both the systematic dual stenting strategy and single stenting strategy demonstrated comparable results in terms of all-cause mortality during medium-term and long-term follow-up. However, the systematic dual stenting strategy showed a tendency towards lower incidence of ST and CV mortality compared to the single stenting strategy during medium-term follow-up. Consequently, the systematic dual stenting strategy yielded superior clinical outcomes for patients with LM bifurcation lesions.

Abstract
The majority of the left ventricular myocardium is supplied by the left main coronary artery. Atherosclerotic obstruction of the left main coronary artery therefore leads to significant myocardial jeopardy. Coronary artery bypass surgery (CABG) has been the gold standard for left main coronary artery disease in the past. However, advancements in technology have established percutaneous coronary intervention (PCI) as a standard, safe and reasonable alternative to CABG, with comparable outcomes. Contemporary PCI of left main coronary artery disease comprises careful patient selection, accurate technique guided by either intravascular ultrasound or optical coherence tomography and - if necessary - physiological assessment using fractional flow reserve. This review focuses on current evidence from registries and randomised trials comparing PCI with CABG, procedural tips and tricks, adjuvant technologies and the triumph of PCI.

Abstract
BACKGROUND Two-stent techniques for percutaneous coronary intervention (PCI) on left main (LM) bifurcation (LMB) lesions are associated with an increased risk of in-stent restenosis (ISR) at left circumflex artery (LCx) ostium but the underlying mechanisms are incompletely understood. This study sought to investigate the association between cyclic change of LM-LCx bending angle (BALM-LCx) and the risk of ostial LCx ISR following two-stent techniques. METHODS In a retrospective cohort of patients undergoing two-stent PCI for LMB lesions, BALM-LCx and distal bifurcation angle (DBA) were computed with 3-dimensional angiographic reconstruction. The analysis was performed both at end-diastole and end-systole, and the angulation change throughout the cardiac cycle was defined as the cardiac motion-induced angulation change (∆CAngle). RESULTS A total of 101 patients were included. The mean pre-procedural BALM-LCx was 66.8 ± 16.1° at end-diastole and 54.1 ± 13.3° at end-systole with a range of 13.0 ± 7.7°. Pre-procedural ∆CBALM-LCx > 16.4° was the most relevant predictor of ostial LCx ISR (adjusted OR 11.58, 95% CI 4.04-33.19; p < 0.001). Post-procedural ∆CBALM-LCx > 9.8° and stent-induced diastolic BALM-LCx change > 11.6° were also related with ostial LCx ISR. DBA was positively correlated with BALM-LCx and showed a weaker association of pre-procedural ∆CDBA > 14.5° with ostial LCx ISR (adjusted OR 6.87, 95% CI 2.57-18.37; p < 0.001). CONCLUSIONS Three-dimensional angiographic bending angle is a feasible and reproducible novel method for LMB angulation measurement. A large pre-procedural cyclic change of BALM-LCx was associated with an increased risk of ostial LCx ISR following two-stent techniques.

Abstract
Serial ostial and distal left main lesions continue to be one of the most difficult tasks for the interventional cardiologist, with many potential complications occurring. We present such a high-risk percutaneous coronary intervention where immediate stent explantation was deemed necessary because the metal deformation and high radial strength of the particular stent platform would prevent an acceptable procedural result if it had been crushed to the vessel wall. The aim of this paper was to discuss left main stent deformation, debate the risks and benefits of stent explantation and finally test in-vitro our theory on "insufficient" crush with stents with high radial strength and compare it with conventional stents. Bench-testing supports our ad-hoc explantation decision showing stent underexpansion, recoil, and malapposition, obtaining an inadequate minimal stent area.

Abstract
OBJECTIVE We sought to compare the clinical outcomes with provisional versus double-stenting strategy for left main (LM) bifurcation percutaneous coronary intervention (PCI). BACKGROUND Despite two recent randomized controlled trials (RCTs) and several observational reports, the optimal LM bifurcation PCI technique remains controversial. METHODS PubMed, Cochrane Central Register of Controlled-Trials (CENTRAL), Clinicaltrials.gov, International Clinical Trial Registry Platform were leveraged for studies comparing PCI bifurcation techniques for LM coronary lesions using second-generation drug eluting stents (DES). The primary outcome was major adverse cardiovascular events (MACE). Secondary outcomes of interest were all-cause mortality, cardiovascular mortality, myocardial infarction (MI), target vessel or lesion revascularization, and stent thrombosis. RESULTS Two RCTs and 10 observational studies with 7105 patients were included. Median follow-up duration was 42 months (IQR: 25.7). Double stenting was associated with a trend towards higher incidence of MACE (odds ratio [OR] 1.20; 95 % confidence interval [CI] 0.94 to 1.53) compared with provisional stenting. This was mainly driven by higher rates of target lesion revascularization (TLR) (OR 1.50; 95 % CI 1.07 to 2.11). There were no statistically significant differences in the incidence of all-cause mortality, cardiovascular mortality, MI, or stent thrombosis. On subgroup analysis according to the study type, provisional stenting was associated with lower MACE and TLR in observational studies, but not in RCTs. CONCLUSION For LM bifurcation PCI using second-generation DES, a provisional stenting strategy was associated with a trend towards lower incidence of MACE driven by statistically significant lower rates of TLR, compared with systematic double stenting. These differences were primarily driven by observational studies. Further RCTs are warranted to confirm these findings.

Abstract
BACKGROUND Left main coronary artery lesions are associated with jeopardy of an outsized area of the myocardium, causing a high incidence of morbidity and mortality. Optimal treatment of coronary bifurcation anatomy remains highly debatable, whether by provisional or two-stent technique. This prospective observational study was designed to investigate the one-year clinical outcomes of unprotected left main coronary artery disease revascularization by percutaneous coronary intervention in a "real-world" setting among Egyptian patients in a prospective single-center registry (at Ain Shams University Hospitals). RESULTS This study included 163 patients who underwent PCI to LM lesions between May 1, 2020, and the end of April in Ain Shams University hospitals. Patients were dichotomized into two groups according to their intended stenting technique, whether provisional or two-stent technique. A total of 142 underwent provisional stenting while 21 were designated for the two-stent technique, mainly DK crush (double kissing). Among the patients with intended provisional stenting, 34 patients underwent the TAP technique. Patients were followed up for the primary endpoints, at the in-hospital setting, at 30 days, and after 1 year. In-hospital death was encountered in 6.34% of cases undergoing provisional stenting, among which 5.36% were due to a cardiovascular cause. Total MACCE was found to be 2.96% in the provisional stenting group versus 4.76% in the two-stent group. Overall, MACCE at 1 year was found to be 22.31% in the provisional group and 30% in the two-stent group (p-value0.57). TVF was recognized in 10% of cases treated by provisional stenting and 30% of cases treated by the two-stent technique (p-value 0.023). CONCLUSIONS LM coronary artery lesions treatment by PCI is considered a safe and beneficial solution. Provisional stenting is the preferred approach bearing in mind that bail-out procedures may be sought in case the SB needs further treatment. Adjunctive assessment by IVUS or FFR may help achieve better outcomes, and efforts should be performed to facilitate their feasibility.

Abstract
Stepwise layered provisional stenting (PS) is the most commonly used strategy to treat coronary bifurcation lesions (CBL). The term 'stepwise layered' emphasises the versatility of this approach that allows the adjustment of the procedure plan according to the CBL complexity, starting with stent implantation in one branch and implantation of a second stent in the other branch only when required. A series of refinements have been implemented over the years to facilitate the achievement of predictable procedural results using this approach. However, despite its simplicity and versatility, operators using this technique require full knowledge of the pitfalls of each procedural step. Part I of this 16th European Bifurcation Club consensus paper provides a detailed step-by-step overview of the pitfalls and technical troubleshooting during the implantation of the first stent using the PS strategy for the treatment of CBL.

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.

Short- and Long-Term Outcomes of Left Main Coronary Artery Stenting in Patients Disqualified from Coronary Artery Bypass Graft Surgery. J Pers Med 2022; 12:348. [PMID: 35330348 PMCID: PMC8953089 DOI: 10.3390/jpm12030348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 02/17/2022] [Accepted: 02/22/2022] [Indexed: 12/10/2022] Open
Abstract
The study aims to evaluate the short- and long-term outcomes of left main percutaneous coronary interventions (LM PCI) in patients disqualified from coronary artery bypass graft surgery (CABG). We included 459 patients (mean age: 68.4 ± 9.4 years, 24.4% females), with at least 1-year follow-up; 396 patients in whom PCI was offered as an alternative to CABG (Group 1); and 63 patients who were disqualified from CABG by the Heart Team (Group 2). The SYNTAX score (29.1 ± 9.5 vs. 23.2 ± 9.7; p < 0.001) and Euroscore II value (2.72 ± 2.01 vs. 2.15 ± 2.16; p = 0.007) were significantly higher and ejection fraction was significantly lower (46% vs. 51.4%; p < 0.001) in Group 2. Patients in Group 2 more often required complex stenting techniques (33.3% vs. 16.2%; p = 0.001). The procedure success rates were very high and did not differ between groups (100% vs. 99.2%; p = 0.882). We observed no difference in periprocedural complication rates (12.7% vs. 7.8%; p = 0.198), but the long-term all-cause mortality rate was higher in Group 2 (26% vs. 21%; p = 0.031). LM PCI in patients disqualified from CABG is an effective and safe procedure with a low in-hospital complication rate. Long-term results are satisfactory.

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.

Diagnostic performance of intravascular ultrasound-based fractional flow reserve versus angiography-based quantitative flow ratio measurements for evaluating left main coronary artery stenosis. Catheter Cardiovasc Interv 2022; 99 Suppl 1:1403-1409. [PMID: 35129284 DOI: 10.1002/ccd.30078] [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: 12/27/2021] [Accepted: 01/02/2022] [Indexed: 11/09/2022]
Abstract
OBJECTIVES We compared the diagnostic performance of the ultrasonic flow ratio (UFR) and quantitative flow ratio (QFR) for left main coronary artery (LMCA) stenosis. BACKGROUND Evaluation of LMCA stenosis remains challenging because of its complex pathogenesis and severity. Computing QFR allows rapid determination of fractional flow reserve (FFR) from coronary angiograms. A novel intravascular ultrasound (IVUS)-based FFR (UFR) allows rapid FFR computation from IVUS images. Neither of the computational approaches required a pressure wire or hyperemia induction. Previous studies have validated the good diagnostic accuracy of QFR and UFR in identifying hemodynamically significant coronary stenosis using FFR as the reference standard. METHODS This retrospective observational study enrolled consecutive patients with intermediate-grade LMCA stenosis who underwent IVUS evaluation. UFR and QFR of all LMCA stenosis patients were assessed, their correlation and agreement were analyzed, and diagnostic performance of UFR in LMCA stenosis was evaluated. RESULTS Eighty-three paired comparisons between UFR and QFR were obtained. UFR excellently correlated with QFR (r = 0.74, p < 0.01). The Bland-Altman plot showed good agreement between UFR and QFR (mean differences: 0.01 ± 0.05, p = 0.34). The area under the curve of UFR for identifying physiological LMCA stenosis was 0.97 (95% confidence interval [CI]: 0.93-1.00, p < 0.01). The overall UFR diagnostic accuracy was 0.95 (95% CI: 0.88-0.99). CONCLUSIONS UFR showed excellent correlation and good agreement with QFR in LMCA stenosis assessment, indicating that it is highly feasible to use UFR for functional evaluation of LMCA stenosis.

Abstract
BACKGROUND Percutaneous coronary intervention (PCI) is increasingly performed in significant left main (LM) lesions. Left untreated, the prognosis is poor, but PCI and coronary bypass surgery (CABG) behold risks as well. Additional long-term outcome data might guide future treatment decisions. METHODS Between 2012 and 2019, all 6783 patients who underwent LM PCI were prospectively enrolled in a national registry. Patients with prior CABG or prior LM PCI, and patients presenting in cardiogenic shock or after out-of-hospital cardiac arrest were excluded. From the remaining 5284 patients, baseline and procedural data as well as long-term survival were assessed. RESULTS The annual rate of LM PCI increased from 422 (2.2% of PCIs) in 2012 to 868 in 2018 (3.0%). By 2018, 71% of the interventional cardiologists performed at least 1 LM PCI a year, though only 5 on average. Use of transradial access (TRA) in LM PCI increased from 20.4% in 2012 to 59.5% in 2019. All-cause mortality was 6.0% at 30 days and 18.5% at a mean follow-up of 33.5 months. Independent predictors of higher long-term mortality were older age, diabetes, multivessel disease, an urgent indication, a suboptimal angiographical result, and non-exclusive use of drug-eluting stents. TRAand higher operator and centre LM PCI experience were independent predictors of a lower long-term mortality. CONCLUSION LM PCI is associated with high short- and long-term mortality. Use of TRA and higher expertise in LM PCI were associated with better survival.

Abstract
BACKGROUND It has not been determined which specific 2-stenting strategy is the best for bifurcation lesions. Our aim was to investigate the clinical outcomes of various 2-stenting strategies in the era of 2nd-generation drug-eluting stents (2G-DES). METHODS AND RESULTS We analyzed 454 patients who finally underwent 2-stenting for a bifurcation lesion, from among 2,648 patients enrolled in the COBIS III registry. The primary outcome was target lesion failure (TLF). Patients were analyzed according to stenting sequence (provisional [main vessel stenting first] vs. systemic [side branch stenting first]) and stenting technique (crush vs. T vs. culotte vs. kissing/V stenting). Overall, 4.4 years' TLF after 2-stenting treatment for bifurcation lesion was excellent: TLF 11.2% and stent thrombosis 1.3%. There was no difference in TLF according to 2-stenting strategy (11.1% vs. 10.5%, P=0.990 for provisional and systemic sequence; 8.6% vs. 14.4% vs. 12.9% vs. 12.2%, P=0.326 for crush, T, culotte, kissing/V technique, respectively). Only left main (LM) disease and a shorter duration of dual antiplatelet therapy (DAPT) were associated with TLF. The distribution of DAPT duration differed between patients with and without TLF, and the time-point of intersection was 2.5 years. Also, the side branch was the most common site of restenosis. CONCLUSIONS The stenting sequence or technique did not affect clinical outcomes, but LM disease and shorter DAPT were associated with TLF, in patients with bifurcation lesions undergoing 2-stenting with 2G-DES.

Long-Term Outcomes After PCI or CABG for Left Main Coronary Artery Disease According to Lesion Location. JACC Cardiovasc Interv 2021; 13:2825-2836.

Abstract
OBJECTIVES The aim of this study was to investigate the impact of lesion site (ostial or shaft vs. distal bifurcation) on long-term outcomes after percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) for left main coronary artery (LMCA) disease. BACKGROUND Long-term comparative data after PCI and CABG for LMCA disease according to lesion site are limited. METHODS Patients from the MAIN-COMPARE (Revascularization for Unprotected Left Main Coronary Artery Stenosis: Comparison of Percutaneous Coronary Angioplasty Versus Surgical Revascularization) registry were analyzed, comparing adverse outcomes (all-cause mortality [a composite outcome of death, Q-wave myocardial infarction, or stroke] and target vessel revascularization) between PCI and CABG according to LMCA lesion location during a median follow-up period of 12.0 years. RESULTS In overall population, the adjusted risks for death and serious composite outcome were higher after PCI than after CABG for distal bifurcation disease, which was mainly separated beyond 5 years. These outcomes were not different for ostial or shaft disease. When comparing drug-eluting stents (DES) and CABG, the adjusted risks for death and serious composite outcome progressively diverged beyond 5 years after DES compared with CABG for distal bifurcation disease (death: hazard ratio: 1.78; 95% confidence interval: 1.22 to 2.59; composite outcome: hazard ratio: 1.94; 95% confidence interval: 1.35 to 2.79). This difference was driven mainly by PCI with a 2-stent technique for distal bifurcation. In contrast, the adjusted risks for these outcomes were similar between DES and CABG for ostial or shaft disease. CONCLUSIONS Among patients with distal LMCA bifurcation disease, CABG showed lower mortality and serious composite outcome rates compared with DES beyond 5 years. However, there were no between-group differences in these outcomes among patients with ostial or shaft LMCA disease.

Abstract
BACKGROUND Side branch (SB) dilation with an ultra-short balloon after main vessel (MV) stenting may minimise stent failure in coronary bifurcation lesions. AIMS We sought to investigate the feasibility and efficacy of the Glider balloon (GB), a side branch (SB)-dedicated balloon 4 mm in length, in coronary bifurcation stenting. METHODS In bench testing, stent configuration was examined with micro-focus computed tomography after crossover stenting followed by GB dilation or kissing balloon inflation (KBI). In the clinical study we performed GB dilatation after MV stenting for 207 lesions in 194 patients. Failure of the GB dilation and additional procedures due to inducible stent failure were investigated as well as adverse cardiac events at 1-year follow-up. RESULTS In bench testing GB dilation maintained cross-sectional stent area without significant deformation and presented effective jailed strut removal in a high-angled bifurcation model. In the clinical study the cohort included left main, true bifurcation lesion, and two-stent treatment in 42.0%, 45.9%, and 14.0%, respectively. The proximal optimisation technique (POT) or POT-like inflation was performed in 82.1%. GB crossing failure, SB stenting due to dissection, and stent deformation requiring correction by KBI or MV dilation occurred in 8.7%, 1.4%, and 5.8%, respectively. Finally, simple GB dilation without KBI was completed in 91.8% for SB dilation. At one-year follow-up, target lesion revascularisation, cardiac death, myocardial infarction, and stent thrombosis were found in 7.2%, 2.1%, 2.1%, and 1.0%, respectively. CONCLUSIONS Simple GB dilation after adequate expansion of the proximal MV stent provided acceptable acute and long-term results as an alternative to KBI.

Abstract
Background The optimal side branch (SB) treatment strategy after simple crossover stenting in bifurcation lesions is still controversial. Objectives The purpose of this study was to compare the long-term outcomes of a 1-stent strategy with simple crossover alone versus with an additional SB–opening procedure in patients with left main (LM) and non-LM coronary bifurcation lesions. Methods Patients who underwent percutaneous coronary intervention with a 1-stent strategy for bifurcation lesions including LM were selected from the COBIS (Coronary Bifurcation Stenting) III registry and divided into the simple crossover–alone group and SB-opening group. Clinical outcomes were assessed by the 5-year rate of target lesion failure (a composite of cardiac death, target vessel myocardial infarction, and target lesion repeat revascularization). Results Among 2,194 patients who underwent the 1-stent strategy, 1,685 (76.8%) patients were treated with simple crossover alone, and 509 (23.2%) patients were treated with an additional SB-opening procedure. Although the baseline SB angiographic disease was more severe in the SB-opening group, the final lumen diameter of the SB was larger. The 5-year observed target lesion failure rate was similar between the 2 groups (7.0% in the simple crossover vs. 6.7% in SB-opening group; hazard ratio: 0.99; 95% confidence interval: 0.66 to 1.48; p = 0.947), even in the subgroup analyses including LM (9.5% vs. 11.3%; p = 0.442) and true bifurcation (5.3% vs. 7.8%; p = 0.362). The results were not changed after an inverse probability of treatment weighting adjustment. There was no difference in the overall and SB-related target lesion revascularization rate in both groups. Conclusions The long-term clinical outcome of the 1-stent strategy with simple crossover alone for coronary bifurcation lesions was acceptable compared to those of additional SB-opening procedures.

Abstract
INTRODUCTION Distal left main (LM) bifurcation disease is one of the most challenging lesion subsets for percutaneous coronary intervention (PCI) and optimal stenting strategy for such complex lesions is still debated. This study aimed to compare clinical outcomes following single versus dual stenting for true distal LM bifurcation lesions. METHODS Patients with true distal LM bifurcation lesions (type 1,1,1 or 0,1,1: both left anterior descending and circumflex artery >2.5 mm diameter) receiving PCI with drug-eluting stents (DES) from two large clinical registries were evaluated. The primary outcome was target-lesion failure (TLF), defined as a composite of cardiac death, target-vessel myocardial infarction (MI), or target-lesion revascularization (TLR). Outcomes were compared with the use of propensity scores and inverse probability-weighting adjustment to reduce treatment selection bias. RESULTS Among 1,002 patients undergoing true distal LM PCI, 440 (43.9%) and 562 (56.1%) were treated with single and dual stents, respectively. The TLF rates at 3 year was 20.3% in the single-stent group and 24.1% in the dual-stenting group (log-rank p = 0.18). The adjusted risk for TLF did not differ significantly between two groups (hazard ratio [HR] with dual-stent vs. single-stent: 1.27, 95% confidence interval [CI]: 0.95-1.71). The adjusted risks for death, MI, repeat revascularization, or stent thrombosis were also similar between the single- and dual-stenting groups. CONCLUSIONS In patients undergoing PCI for true distal LM disease, single- and dual-stent strategies showed a similar adjusted risk of TLF at 3 years. Our findings should be confirmed or refuted through large, randomized clinical trials.

Abstract
It is of critical importance to correctly assess the significance of a left main lesion. Underestimation of significance beholds the risk of inappropriate deferral of revascularization, whereas overestimation may trigger major but unnecessary interventions. This article addresses the invasive physiological assessment of left main disease and its role in deciding upon revascularization. It mainly focuses on the available evidence for fractional flow reserve and instantaneous wave-free ratio, their interpretation, and limitations. We also discuss alternative invasive physiological indices and imaging, as well as the link between physiology, ischemia, and prognosis.

Abstract
Provisional stenting is considered the gold standard approach for most bifurcation lesions, but the benefit of routine side branch (SB) strut dilatation has not been fully elucidated. A benchtop model was used to determine the benefits of routine side branch (SB) dilatation techniques on strut apposition, acute thrombogenicity, and flow disruption. Three different provisional bifurcation techniques were compared: no SB dilatation "keep it open" method (KIO), sequential balloon dilatation (SBD), and kissing balloon inflation (KBI). Stents were deployed in a silicon bifurcation model and perfused with blood at a flow rate of 200 ml/min for 60 min. Optical coherence tomography (OCT) pullbacks were obtained before and after flow perfusion to conduct strut analysis and acute thrombus measurement respectively. Computational fluid dynamics (CFD) models were created using OCT pullbacks and simulated based on experimental conditions to analyze flow disruption. The strut analysis showed that KBI had the lowest percentage of floating (10.6 ± 2.3%) (p = 0.0004) and malapposed (41.2 ± 8.5%) struts (p = 0.59), followed by SBD and then KIO. This correlated to KBI having the lowest amount of thrombus formed at the SB, followed by SBD, with KIO being the most thrombogenic (KBI: 0.84 ± 0.22mm2, SBD: 1.17 ± 0.25mm2, KIO: 1.31 ± 0.36mm2, p = 0.18). CFD models also predicted a similar trend, with KBI having the lowest amount of area of high shear rate as well as flow recirculation. Based on this benchtop model, SB intervention strategies demonstrated a reduction in number of struts and resulting thrombogenicity at the bifurcation ostia. Graphical abstract.

Abstract
Objectives To compare the effectiveness and safety of the Braidin® slender 7 Fr sheath with a standard 6 Fr sheath for treating left main bifurcation disease. Methods From January 2017 to March 2019, 277 patients with left main bifurcation disease who underwent the transradial approach for percutaneous coronary intervention were divided into the slender 7 Fr sheath group (Braidin® slender 7 Fr sheath, n = 154) and standard 6 Fr sheath group (n = 123). Pathological features, surgical effect, and complications were evaluated. Results The rate of using the classic crush technique was significantly higher in the slender 7 Fr sheath group than in the standard 6 Fr sheath group. The slender 7 Fr sheath group had a significantly shorter operation time than the standard 6 Fr sheath group. There were no significant differences in the radial artery occlusion rate after surgery and at 1 month of follow-up between the groups. Multivariate logistic regression analysis showed that 6 Fr and Braidin slender 7 Fr sheaths did not predict radial artery occlusion. Conclusion The Braidin slender 7 Fr sheath has a superior operative process and similar safety for the radial artery as that of the standard 6 Fr sheath for treating left main bifurcation disease.

Clinical Implications of Bifurcation Angles in Left Main Bifurcation Intervention Using a Two-Stent Technique. J Interv Cardiol 2020; 2020:2475930.

Abstract
Objectives The aim of this study was to assess the clinical impact of 3 bifurcation angles in left main (LM) bifurcation treated with the 2-stent technique. Background Data are limited regarding the impact of bifurcation angles after LM percutaneous coronary intervention (PCI). Methods Using patient-level 4 multicenter registries in Korea, 462 patients undergoing LM bifurcation PCI with the 2-stent technique were identified (181 crush, 167 T-stenting; 63% 1st generation drug-eluting stent (DES), 37% 2nd generation DES). Three bifurcation angles, between the LM and left anterior descending (LAD), the LM and left circumflex (LCX), and the LAD and LCX, were measured. The primary outcome was target lesion failure (TLF), a composite of cardiac death, myocardial infarction, and target lesion revascularization (TLR). Results In patients treated with the crush technique, the best cutoff value (BCV) to predict TLF was 152° of the LM-LAD angle. In the crush group, a significantly higher TLF rate, mostly driven by TLR, was observed in the LM-LAD angle ≥152° group compared with the <152° group (35.7% vs. 14.6%; adjusted hazard ratio 3.476; 95% confidence interval 1.612–7.492). An LM-LAD angle ≥152° was an independent predictor of TLF. In the T-stenting, no bifurcation angle affected the clinical outcomes. Conclusions In LM bifurcation PCI using the 2-stent technique, wide LM-LAD angle (≥152°) was associated with a greater risk of TLF in the crush, whereas none of the bifurcation angles affected T-stenting outcomes.

Abstract
BACKGROUND Proximal optimization technique (POT) is a key step during left main (LM) bifurcation stenting. However, after crossover stenting, the ideal position of POT balloon is unclear. We sought to evaluate the biomechanical impact of different POT balloon positions during LM cross-over stenting procedure. METHODS We reconstructed the patient-specific LM bifurcation anatomy, using coronary computed tomography angiography data of 5 consecutive patients (3 males, mean age 66.3 ± 21.6 years) with complex LM bifurcation disease, defined as Medina 1,1,1, evaluated between 1st January 2018 to 1st June 2018 at our center. Finite element analyses were carried out to virtually perform the stenting procedure. POT was virtually performed in a mid (marker just at the carina cut plane), proximal (distal marker 1 mm before the carina) and distal (distal marker 1 mm after the carina) position in each investigated case. Final left circumflex obstruction (SBO%), strut malapposition, elliptical ratio and stent malapposition were evaluated. RESULTS The use of both proximal and distal POT resulted in a smaller LM diameter compared to the mid POT. SBO was significantly higher in both proximal and distal configurations compared to mid POT: 38.3 ± 5.1 and 29.3 ± 3.1 versus 18.3 ± 3.6%, respectively. Similarly stent malapposition was higher in both proximal and distal configurations compared to mid POT: 1.3 ± 0.4 and 0.82 ± 1.8 versus 0.78 ± 1.2, respectively. CONCLUSIONS Mid POT offers the best results in terms of LCx opening maintaining slightly smaller but still acceptable LM and LAD diameters compared to alternative POT configuration.

Abstract
OBJECTIVES In a coronary bifurcation bench model, to determine the effects of side branch (SB) wire crossing position and balloon position on the stent scaffolding after the final proximal optimization technique (POT). BACKGROUND POT performed as a final step after SB dilatation or kissing balloon inflation (KBI) has been widely advocated despite limited evidence. METHODS Thirty-one stent implantations in bifurcation phantoms were performed using a one-stent provisional technique with (KBI) (n = 13), with POT-side-POT technique (n = 12) or with the two-stent culotte technique (n = 6). SB wiring was performed through either a proximal or a distal stent cell and confirmed by optical coherence tomography. Final POT was performed with the balloon positioned either across or proximal to the SB takeoff. The area of the opened stent cell in front of the SB was assessed by 3D reconstructed microcomputation tomography scans performed before and after Final POT. RESULTS In cases with metallic carina, final POT across the SB takeoff caused SB rejailing. Regardless of stent technique and wire position, a Final POT across the SB takeoff reduced the SB cell opening area by 43% [32%;58%] (n = 15). The largest reduction (54-70%) was found after the POT-side-POT technique in procedures with a proximal wiring. Final POT performed proximal to the SB takeoff caused limited or no SB cell opening area reduction (4% [0.6%;6%] [n = 16]). CONCLUSION Final POT with balloon positioned across the SB takeoff in a narrow angle bifurcation reduces largest stent cell area in front of the SB ostium and may cause SB rejailing in cases with metallic carina.

Long-Term Efficacy of Extended Dual Antiplatelet Therapy After Left Main Coronary Artery Bifurcation Stenting. Am J Cardiol 2020; 125:320-327.

Abstract
Limited data exist on the long-term efficacy of extended dual antiplatelet therapy (DAPT) after left main coronary artery (LMCA) bifurcation stenting. This study investigated the long-term clinical outcomes associated with long-term DAPT after LMCA bifurcation stenting. Using data from the multicenter KOMATE and COBIS registries, we analyzed 1,142 patients who received a drug-eluting stent for a LMCA bifurcation lesion and who experienced no adverse events for 12 months after the index procedure. Patients were divided into 2 groups: DAPT >12 months (n = 769) and DAPT ≤12 months (n = 373). The primary end point was major adverse cardiovascular events (MACEs), as a composite of cardiac death, myocardial infarction, stroke, and stent thrombosis, over 5 years of follow-up. We further performed propensity score adjustment for clinical outcomes. DAPT >12 months afforded a lower MACE rate than DAPT ≤12 months (2.3% vs 5.4%, adjusted hazard ratio [HR] 0.37; 95% confidence interval [CI] 0.19 to 0.71; p = 0.003). The use of DAPT for >12 months was an independent predictor of a reduced likelihood of MACEs (HR 0.34; 95% CI 0.17 to 0.67; p = 0.002). A DAPT score ≥2, chronic kidney disease, and age >75 years were significant independent predictors of MACEs. In subgroup analysis, the use of DAPT for >12 months consistently resulted in better clinical outcomes across all subgroups, especially among patients with ACS, compared with the use of DAPT for ≤12 months. In conclusion, an extended duration of DAPT reduces MACE rates after LMCA bifurcation stenting.

Abstract
Left main bifurcation percutaneous coronary intervention is a challenging subset that requires expertise in techniques that are in constant modification. Imaging is important in lesion preparation and optimising outcomes. The interventionalist needs to be highly skilled in the different techniques, as missteps may lead to stent thrombosis and critical in-stent restenosis. Lesion classification between simple and complex identifies those who would best benefit from a two-stent technique. Current technical approaches and practice considerations are summarised in this manuscript.

Abstract
OBJECTIVES This study sought to investigate the long-term clinical effects of stent generation and stent strategy for left main coronary artery (LMCA) bifurcation lesion treatment. BACKGROUND Limited data are available to assess long-term clinical outcomes after stenting, including use of current-generation drug-eluting stent (C-DES) for treatment of LMCA bifurcation lesions. METHODS A total of 1,353 patients who were recorded in 2 multicenter real-world registries were treated by either early-generation drug-eluting stent (E-DES) (n = 889) or C-DES (n = 464). Primary endpoint was major adverse cardiovascular events (MACE). MACE was defined as a composite of cardiac death or myocardial infarction, stent thrombosis, and target lesion revascularization rates during 3-year follow-up. The authors further performed propensity-score adjustment for clinical outcomes. RESULTS During 3-year follow-up, the overall MACE rate was 8.7%. Use of a 1-stent strategy resulted in better clinical outcomes than use of a 2-stent strategy (4.7% vs. 18.6%, hazard ratio [HR]: 3.71; 95% confidence interval [CI]: 2.55 to 5.39; p < 0.001). Use of C-DES resulted in a lower MACE rate compared with using E-DES (4.6% vs. 10.9%, HR: 0.55; 95% CI: 0.34 to 0.89; p = 0.014), especially for the 2-stent strategy. For patients with C-DES, the presence of chronic kidney disease and pre-intervention side branch diameter stenosis ≥50% were significant independent predictors of MACE. CONCLUSIONS Intervention of LMCA bifurcation lesions using DES implantation demonstrated acceptable long-term clinical outcomes, especially in C-DES patients. Use of a 1-stent strategy resulted in better clinical benefits than using a 2-stent strategy.

Effect of increasing age on percutaneous coronary intervention vs coronary artery bypass grafting in older adults with unprotected left main coronary artery disease: A meta-analysis and meta-regression. Clin Cardiol 2019; 42:1071-1078. [PMID: 31486094 PMCID: PMC6837018 DOI: 10.1002/clc.23253] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2019] [Revised: 08/16/2019] [Accepted: 08/20/2019] [Indexed: 11/11/2022] Open
Abstract
Background Older adults (≥70‐year‐old) are under‐represented in the published data pertaining to unprotected left main coronary artery disease (ULMCAD). Hypothesis: Percutaneous coronary intervention (PCI) might be comparable to coronary artery bypass grafting (CABG) for revascularization of ULMCAD. Methods We compared PCI versus CABG in older adults with ULMCAD with an aggregate data meta‐analyses (4880 patients) of clinical outcomes [all‐cause mortality, myocardial infarction (MI), repeat revascularization, stroke and major adverse cardiac and cerebrovascular events(MACCE)] at 30 days, 12‐24 months & ≥36 months in patients with mean age ≥70 years and ULMCAD. A meta‐regression analysis evaluated the effect of age on mortality after PCI. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using random‐effects model. Results All‐cause mortality between PCI and CABG was comparable at 30‐days (OR0.77, 95% CI 0.42‐ 1.41) and 12‐24‐months (OR 1.22, 95% CI 0.78‐1.93). PCI was associated with a markedly lower rate of stroke at 30‐day follow‐up in octogenarians (OR 0.14, 95% CI 0.02‐0.76) but an overall higher rate of repeat revascularization. At ≥36‐months, MACCE (OR 1.26,95% CI 0.99‐1.60) and all‐cause mortality (OR 1.39, 95% CI 1.00‐1.93) showed a trend favoring CABG but did not reach statistical significance. On meta‐regression, PCI was associated with a higher mortality with advancing age (coefficient=0.1033, p=0.042). Conclusions PCI was associated with a markedly lower rate of early stroke in octogenarians as compared to CABG. All‐cause mortality was comparable between the two arms with a trend favoring CABG at ≥36‐months.PCI was however associated with increasing mortality with advancing age as compared to CABG.

Abstract
The advent of coronary angiography in the 1960s allowed for the risk stratification of patients with stable angina. Patients with unprotected left main coronary artery disease have an increased risk of death related to the large amount of myocardium supplied by this vessel. Although coronary angiography remains the preferred imaging modality for the evaluation of left main coronary artery stenosis, this technique has important limitations. Angiograms of the left main coronary artery segment can be difficult to interpret, and almost one-third of patients can be misclassified when fractional flow reserve is used as the reference. In patients with clinically significant unprotected left main coronary artery disease, surgical revascularization was shown to improve survival compared with medical therapy and has been regarded as the treatment of choice for unprotected left main coronary artery disease. Two large-scale clinical trials published in 2016 support the usefulness of catheter-based revascularization in selected patients with unprotected left main coronary artery disease. In this Review, we describe the pathophysiology of unprotected left main coronary artery disease, discuss diagnostic approaches in light of new noninvasive and invasive imaging techniques, and detail risk stratification models to aid the Heart Team in the decision-making process for determining the best revascularization strategy for these patients.

Abstract
PURPOSE OF REVIEW This article reviews the latest data on unprotected left main (ULM) percutaneous coronary intervention (PCI) versus coronary artery bypass graft (CABG) surgery, with a focus on the NOBLE and EXCEL trials. RECENT FINDINGS In EXCEL trial, the primary endpoint at 3 years was 15.4% in the PCI group and 14.7% in the CABG group (p = 0.02 for non-inferiority of PCI versus CABG). In NOBLE, the primary endpoint at 5 years was 28% and 18% for PCI and CABG, respectively (HR 1.51, CI 1.13-2.0, which did not meet the criteria for non-inferiority of PCI to CABG; p for superiority of CABG was 0.0044). Higher repeat revascularization and non-procedural myocardial infarction were noted in PCI group but there was no difference in all-cause or cardiac mortality between the two groups. A heart team approach with appropriate patient selection, careful assessment of LM lesions, and meticulous procedural technique makes PCI a valid alternative to CABG for ULM stenosis.

Abstract
Left main percutaneous coronary intervention is an acceptable alternative to coronary artery bypass grafting, and in experienced hands, excellent procedural results can be obtained. A systematic approach to stenting and meticulous attention to detail are required. For most lesions, a single-stent provisional approach is sufficient, but for the more complex lesion, a 2-stent technique is required. Herein, the optimal approach to left main lesion assessment and percutaneous intervention is described.

Abstract
Complex bifurcations have been suggested to be better approached by a planned double stent technique; however, recent randomized trials have shown better outcomes of provisional compared to planned two-stent strategy, in terms of both short-term efficacy and safety. In left main (LM) bifurcations, double kissing (DK)-Crush has demonstrated its superiority over Culotte and provisional-T in terms of restenosis and stent thrombosis, gaining respect as one of the most performant techniques for bifurcations stenting. On the other hand, the Nano-Crush technique has recently become part of the repertoire of double stenting techniques, providing evidence that the use of ultrathin strut stents and very minimal crush would be beneficial for both the physiological and rheological properties of the complex bifurcations, even in LM scenario, leading to a lower rate of thrombosis and restenosis at both side branch and true carina. Finally, the newest generation of ultrathin strut stents are gaining a reputation for its safe and effective use in LM treatment thanks to improved design with increased expansion rate capable of LM treatment up to 5-6 mm diameter. The modern crush techniques, such as DK-Crush and Nano-Crush, are providing excellent results on mid and long-term follow up, suggesting that minimal crushing obtained using ultra-thin stents is a good way to obtain surgical-like outcomes in the treatment of complex LM bifurcation disease.

Abstract
Left main coronary artery (LMCA) stenosis has long been recognized as a marker of increased morbidity and mortality. Current treatment algorithms for LMCA stenosis consider both percutaneous coronary intervention (PCI) with drug eluting stents (DES) and coronary bypass surgery, each with advantages based on individual patient characteristics. Since the LMCA is the largest artery in the coronary tree, plaque volume and calcification is greater than other coronary segments and often extends to the distal bifurcation segment. In LMCA bifurcation lesions, larger minimal stent area is strongly associated with better outcome in the DES era. Plaque modification strategies such as rotational, orbital, or laser atherectomy are effective mechanisms to reduce plaque volume and alter compliance, facilitating stent delivery and stent expansion. We present a case of a calcified, medina class 1,1,1 LMCA lesion where intravascular ultrasound (IVUS) and orbital atherectomy were employed for optimal results. In this context, we review the evidence of plaque modification devices and the rationale for their use in unprotected left main PCI.

Abstract
Percutaneous coronary intervention of the left main coronary artery has evolved through registries and meta analyses, supported by results from the EXCEL [Everolimus-Eluting Stents (EES) or Bypass Surgery for Left Main Coronary Artery Disease] and NOBLE (Percutaneous Coronary Angioplasty versus Coronary Artery Bypass Grafting in Treatment of Unprotected Left Main Stenosis) trials as an acceptable alternative to coronary artery bypass grafting in patients with low and intermediate Syntax scores. Advances in stenting strategies and the availability of larger diameter drug-eluting stents improve patient safety and optimize procedural and patient outcomes.

Abstract
BACKGROUND The optimal final optimization technique to be used in patients after Cross Over Left main stenting remainsdebatable. AIM We evaluate the impact of the post-optimization technique (POT), kissing balloon (KB) and the POT-side-POT techniques on both cardiovascular mortality and event-free survival in patients receiving left main (LM) cross-over stenting for an isolated/distal bifurcation LM disease. METHODS Clinical and instrumental records of 128 consecutive patients (102 males, mean age 73.39 ± 9.54 years old) with isolated distal/bifurcation LM disease and bypass surgery contraindications or refusal enrolled to receive LM cross-over stenting between the 1st January 2012 and the 1st January 2017 at two institutions: the Rovigo General Hospital (Rovigo, Italy) and the Alexandrovka Hospital University School of Medicine (Sofia, Bulgaria). Patients has been divided into three groups (POT, KB and POT-side-POT) according the optimal final optimization technique used while the 5-year cardiovascular mortality has been evaluated using the log-rank (Mantel-Cox) analysis. RESULTS Baseline angiographic characteristics of the LM disease were mostly equivalent among the three groups. Over a global follow-up of 61.03 ± 0.92 months, the rates of target vessel revascularization, acute myocardial infarction, and stent thrombosis, were not different among groups. Patients treated with POT had a slightly better long-term survival. CONCLUSIONS None of these optimization techniques appeared to have clearly better long-term outcomes after LM Cross-over stenting in our retrospective study. POT resulted in a slightly better survival compared to Pot-sid-POT and KB.
