Shi H, Hyasat K, Deshmukh T, Ada C, Chiha J, Asrress K, Liou K. Optimal Percutaneous Treatment Approach to Unprotected Ostial Left Anterior Descending Artery Disease: A Meta-Analysis and Systematic Review. Heart Lung Circ 2024; 33:1123-1135. [PMID: 38614944 DOI: 10.1016/j.hlc.2024.02.006] [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: 08/07/2023] [Revised: 01/28/2024] [Accepted: 02/04/2024] [Indexed: 04/15/2024]
Abstract
BACKGROUND The optimal management strategy for significant unprotected ostial left anterior descending artery (LAD) disease remains undefined. Merits of the two most common percutaneous approaches are considered in this quantitative synthesis. METHOD A meta-analysis was performed to compare ostial stenting (OS) and crossover stenting (CS) in the treatment of unprotected ostial LAD stenosis. The primary outcome is the disparity in target lesion revascularisation (TLR). The Mantel-Haenszel method was employed with random effect model, chosen a priori to account for heterogeneity among the included studies. RESULTS Seven studies comprising 1,181 patients were included in the analyses. Of these, 482 (40.8%) patients underwent CS. Overall, there was a statistically significant trend in favour of CS (odds ratio 0.51, 95% confidence interval 0.30-0.86, p=0.01) with respect to the rate of TLR at follow-up. This remained true when TLR involving the left circumflex artery (LCx) was considered, even when there was a greater need for unintended intervention to the LCx during the index procedure (odds ratio 6.68, 95% confidence interval: 1.69-26.49, p=0.007). Final kissing balloon inflation may reduce the need for acute LCx intervention. Imaging guidance appeared to improve clinical outcomes irrespective of approach chosen. CONCLUSIONS In the percutaneous management of unprotected ostial LAD disease, CS into the left main coronary artery (LMCA) appeared to reduce future TLR. Integration of intracoronary imaging was pivotal to procedural success. The higher incidence of unintended LCx intervention in the CS arm may be mitigated by routine final kissing balloon inflation, although the long-term implication of this remains unclear. In the absence of randomised trials, clinicians' discretion remains critical.

Abstract
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.

Abstract
Coronary angiography has a limited ability to predict the functional significance of intermediate coronary lesions. Hence, physiological assessment of coronary lesions, via fractional flow reserve (FFR) or instantaneous wave-free ratio (iFR), has been introduced to determine their functional significance. An accumulating body of evidence has consolidated the role of physiology-guided revascularization, particularly among patients with stable ischemic heart disease. The use of FFR or iFR to guide decision-making in patients with stable ischemic heart disease and intermediate coronary lesions received a class I recommendation from major societal guidelines. Nevertheless, the role of coronary physiology testing is less clear among certain patients' groups, including patients with serial coronary lesions, acute coronary syndromes, aortic stenosis, heart failure, as well as post-percutaneous coronary interventions. In this review, we aimed to discuss the utility and clinical evidence of coronary physiology (mainly FFR and iFR), with emphasis on those specific patient groups.

Post-procedural and long-term functional outcomes of jailed side branches in stented coronary bifurcation lesions assessed with side branch Murray law-based quantitative flow ratio. Front Cardiovasc Med 2023; 10:1217069. [PMID: 37600052 PMCID: PMC10435891 DOI: 10.3389/fcvm.2023.1217069] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Accepted: 07/19/2023] [Indexed: 08/22/2023] Open
Abstract
Introduction In coronary bifurcation lesions treated with percutaneous coronary intervention (PCI) using a 1-stent strategy, the occurrence of side branch (SB) compromise may lead to long-term myocardial ischemia in the SB territory. Murray law-based quantitative flow ratio (μQFR) is a novel angiography-based approach estimating fractional flow reserve from a single angiographic view, and thus is more feasible to assess SB compromise in routine practice. However, its association with long-term SB coronary blood flow remains unknown. Methods A total of 146 patients with 313 non-left main bifurcation lesions receiving 1-stent strategy with drug-eluting stents was included in this retrospective study. These lesions had post-procedural Thrombolysis in Myocardial Infarction (TIMI) flow grade 3 in SBs, and documented angiographic images of index procedure and 6- to 24-month angiographic follow-up. Post-procedural SB μQFR was calculated. Long-term SB coronary blood flow was quantified with the TIMI grading system using angiograms acquired at angiographic follow-up. Results At follow-up, 8 (2.6%), 16 (5.1%), 61 (19.5%), and 228 (72.8%) SBs had a TIMI flow grade of 0, 1, 2, and 3, respectively. The incidences of long-term SB TIMI flow grade ≤1 and ≤2 both tended to decrease across the tertiles of post-procedural SB μQFR. The receiver operating characteristic curve analyses indicated the post-procedural SB μQFR ≤0.77 was the optimal cut-off value to identify long-term SB TIMI flow grade ≤1 (specificity, 37.50%; sensitivity, 87.20%; area under the curve, 0.6673; P = 0.0064), and it was independently associated with 2.57-fold increased risk (adjusted OR, 2.57; 95% CI, 1.02-7.25; P = 0.045) in long-term SB TIMI flow grade ≤1 after adjustment. Discussion Post-procedural SB μQFR was independently associated with increased risk in impaired SB TIMI flow at long-term follow-up. Further investigations should focus on whether PCI optimization based on μQFR may contribute to improve SB flow in the long term.

Long-term prognostic value of Murray law-based quantitative flow ratio in jailed left circumflex coronary artery after left main crossover stenting. Sci Rep 2023; 13:4391. [PMID: 36927741 PMCID: PMC10020166 DOI: 10.1038/s41598-023-30991-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2022] [Accepted: 03/06/2023] [Indexed: 03/18/2023] Open
Abstract
We aimed to evaluate the impact of new Murray law-based QFR of jailed left circumflex coronary artery (LCx) on long-term clinical outcomes after left main coronary artery (LM) simple crossover stenting. 164 patients who underwent LM-to-left anterior descending coronary artery simple crossover stenting and had appropriate angiographic view of LCx for QFR computation were enrolled. The primary clinical outcome was the 5-year target lesion failure (TLF), defined as a composite of cardiac death, a target vessel myocardial infarction or target lesion repeat revascularization. The mean QFR of the LCx after LM stent implantation was 0.88 ± 0.09, and 29 patients (17.7%) had a low QFR (< 0.80), which was significantly associated with a higher 5-year rate of TLF when compared with the high QFR group (27.6% vs. 6.7%; HR: 4.235; 95% CI 1.21-14.95; p = 0.0015). The 5-year LCx ostium-related TLR rate in the low QFR group was also higher (17.2% vs. 3.0% in the high QFR group; HR: 6.07, 95% CI 1.63-22.59, p = 0.002). In a multivariate Cox regression analysis, a low QFR in the LCx after LM stenting was an independent predictor of the 5-year TLF rate (HR: 3.21, 95% CI 1.21-8.53; p = 0.019). ROC analysis showed that QFR a negative predictive value (NPV) of 89.6% ([AUC] 0.73, 95% CI 0.58-0.88, p < 0.05), the cutoff point is 0.85. The patients with a low QFR (< 0.80) in jailed LCX after LM simple crossover stenting had worse 5-year outcomes than those with a high QFR. Conversely, a QFR ≥ 0.85 of jailed LCx could serve as a good predictor of low risk of adverse outcome in LCx ostium. The QFR computation of the jailed LCx may be helpful to determine whether an additional procedure is required for the jailed side branch.

Abstract
Owing to a large-jeopardized myocardium, left main coronary artery disease (LMCAD) represents the substantial high-risk anatomical subset of obstructive coronary artery disease. For several decades, coronary artery bypass grafting (CABG) has been the "gold standard" treatment for LMCAD. Along with advances in CABG, percutaneous coronary intervention (PCI) has also dramatically evolved over time in conjunction with advances in the stent or device technology, adjunct pharmacotherapy, accumulated experiences, and practice changes, establishing its position as a safe, reasonable treatment option for such a complex disease. Until recently, several randomized clinical trials, meta-analyses, and observational registries comparing PCI and CABG for LMCAD have shown comparable long-term survival with tradeoffs between early and late risk-benefit of each treatment. Despite this, there are still several unmet issues for revascularization strategy and management for LMCAD. This review article summarized updated knowledge on evolution and clinical evidence on the treatment of LMCAD, with a focus on the comparison of state-of-the-art PCI with CABG.

Abstract
INTRODUCTION AND OBJECTIVES The use of a pressure wire as a jailed wire to evaluate side branch results during provisional stenting seems feasible. However, safety concerns exist due to the mechanical damage of the wire and the lack of prospective data evaluating the prognosis of patients treated using this technique. This study sought to evaluate the structural damage of the pressure wire in patients treated using the jailed pressure wire technique and to assess mid-term clinical outcomes. METHODS We enrolled 99 patients with single bifurcation lesions and provisional stenting as the strategy of choice. A jailed pressure wire was used to guide side branch intervention according to the instantaneous wave-free ratio (iFR). A total of 114 patients and the respective nonpolymer-coated jailed wires were used as historical controls. Guidewire damage was evaluated by stereomicroscopy. The primary endpoint was significant microscopic damage. Major adverse cardiac events were evaluated at 2-year follow-up. RESULTS Significant microscopic damage was more frequent in pressure wires than in nonpolymer-coated wires (53.5% vs 22.8%, P<.001). There were no fractures in either group. There were fewer side branch interventions in the pressure wire group (postdilation/kissing balloon, 32.3% vs 56.1%, P=.001; stenting, 0.0% vs 2.6%, P=.104). The 2-year rate of major adverse cardiac events was similar between the 2 groups (HRadj, 0.42; 95%CI, 0.10-1.73; P=.229). CONCLUSIONS Pressure wires were less resistant to jailing than conventional nonpolymer-coated wires. Patients treated with iFR-guided provisional stenting required fewer side branch interventions but had similar 2-year clinical outcomes than patients treated with the angiography-guided technique.

Abstract
Due to its anatomical features, patients with an obstruction of the left main coronary artery (LMCA) have an increased risk of death. For years, coronary artery bypass grafting (CABG) has been considered as a gold standard for revascularization. However, notable advancements in the field of percutaneous coronary intervention (PCI) led to its acknowledgement as an important treatment alternative, especially in patients with low and intermediate anatomical complexity. Although recent years brought several random clinical trials that investigated the safety and efficacy of the percutaneous approach in LMCA, there are still uncertainties regarding optimal revascularization strategies. In this paper, we provide a comprehensive review of state-of-the-art diagnostic and treatment methods of LMCA disease, focusing on percutaneous methods.

Abstract
Coronary artery bifurcation lesions are frequently encountered in cardiac catheterization laboratories and are associated with more complex procedures and worse clinical outcomes than nonbifurcation lesions. Therefore, anatomical and physiological assessment of bifurcation lesions before, during, and after percutaneous coronary intervention is of paramount clinical importance. Physiological assessment can help interventionalists appreciate the hemodynamic significance of coronary artery disease and guide ischemia-directed revascularization. However, it is important to understand that the physiological approach for bifurcation disease is more important than simply using physiological indexes for its assessment. This joint consensus document by the Korean, Japanese, and European bifurcation clubs presents the concept of a physiological approach for coronary bifurcation lesions, as well as current knowledge, practical tips, pitfalls, and future directions of applying physiological indexes in bifurcation percutaneous coronary intervention. This document aims to guide interventionalists in performing appropriate physiology-based assessments and treatment decisions for coronary bifurcation lesions.

Abstract
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.

Comparison of adenosine-independent pressure indices to fractional flow reserve in stent-jailed bifurcation side branches. Catheter Cardiovasc Interv 2022; 100:369-377. [PMID: 35723275 DOI: 10.1002/ccd.30298] [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: 06/21/2021] [Revised: 05/14/2022] [Accepted: 05/29/2022] [Indexed: 01/10/2023]
Abstract
OBJECTIVES AND BACKGROUND This study aims to evaluate whether the high correlation and classification agreement of the instantaneous wave-free ratio (iFR) and the resting distal coronary to aortic pressure ratio (Pd /Pa ) with the fractional flow reserve (FFR) can be confirmed in stent-jailed side branches (J-SB). METHODS Consecutive patients (n = 49) undergoing provisional stenting were prospectively enrolled and a physiological assessment of the J-SB (n = 51) was performed. FFR, iFR, and Pd /Pa were measured and the hemodynamic relevance was determined using cutoff values of ≤0.80, ≤0.89, and ≤0.92, respectively. RESULTS Both iFR (r = 0.75) and Pd /Pa (r = 0.77) correlated closely with FFR. Classification agreement with FFR was 78% for iFR (81% sensitivity, 77% specificity) and 75% for Pd /Pa (63% sensitivity and 80% specificity). However, angiographic diameter stenosis and pressure indices correlated poorly. For a threshold of ≥70% stenosis, agreement concerning hemodynamic relevance was found in 59% for FFR, 69% for iFR, and 61% for Pd /Pa . CONCLUSION As reported for other lesion types, FFR and the adenosine-independent pressure indices iFR and Pd /Pa show close correlation and a high classification agreement of approximately 75%-80% in J-SB. Therefore, iFR can be regarded as a recommendable alternative to FFR for the guidance of provisional stenting in bifurcation lesions.

Protective ballooning technique for prevention of side branch occlusion in coronary nonleft main true bifurcation lesions: A single-center study.

Abstract
OBJECTIVES We aimed to evaluate the efficacy of a protective ballooning technique in preventing side branch (SB) occlusion and to assess the long-term clinical outcomes for coronary nonleft main true bifurcation lesions. BACKGROUND SB occlusion is a major complication associated with percutaneous coronary intervention (PCI) for coronary bifurcation lesions. METHODS Patients were consecutively enrolled and randomly assigned to protective ballooning technique or jailed wire technique group. Periprocedural and long-term clinical outcomes were compared. RESULTS Patients in the protective ballooning technique (n = 173) and jailed wire technique (n = 167) groups were followed up for 12 months. SB occlusion occurred in one patient (0.6%) and nine patients (5.4%) in each group, respectively. The proportion of thrombolysis in myocardial infarction (TIMI) flow grade 3 of the SB was higher in the protective ballooning technique group (98.8% vs. 95.2%, p < 0.05). SB rewiring was necessary in one patient in the protective ballooning technique group (0.6%) with provisional stenting, significantly lower than that in the jailed wire technique group (seven patients, 4.2%; p = 0.03). Periprocedural myocardial infarction occurred in three (1.73%) and six (3.59%) patients in the protective ballooning technique and jailed wire technique groups without significant difference, respectively. Major adverse cardiovascular events at 12 months were similar in both groups. CONCLUSIONS Protective ballooning technique is effective for the prevention of SB occlusion in nonleft main true bifurcation lesions and had favorable long-term outcomes at the 12-month follow-up.

Abstract
Although clinical outcomes after percutaneous coronary intervention (PCI) are improving, the long-term risk for target vessel failure remains concerning. Although the application of intravascular imaging and physiological indexes significantly improves outcomes, their routine use in practice remains limited. Nevertheless, merely using these modalities is not enough, and to truly improve patient outcomes, optimal intravascular dimensions with minimal vascular injury should be targeted. When assessing post-PCI results using either type of physiological or imaging technology, a broad spectrum of stent- and vessel-related anomalies can be expected. As not all of these issues warrant treatment, a profound knowledge of what to expect and how to recognize and when to treat these intraluminal problems is needed. Additionally, promising new modalities such as angiography-derived coronary physiology and hybrid imaging catheters are becoming available. The authors provide an overview of the currently available tools and techniques to define suboptimal PCI and when to apply these technologies to improve outcomes.

Abstract
Calcified coronary artery bifurcation lesions (CBL) remain a challenge for the interventional cardiologist. Evidence regarding treatment of CBL is minimal. Optimal plaque modification is the most important step prior to stent deployment. Provisional stenting is the preferred strategy for most bifurcation lesions. However, two-stent strategy should be considered for BL with compromised large SB (>2.5 mm) supplying a large territory, >70% SB stenosis and lesions more than 5 mm long. In this contemporary review article, we present a simplified approach to treating CBL and demonstrate the approach to specific case examples using our newly developed mobile application, BifurcAID.

Abstract
OBJECTIVES We examined the incidence of side branch (SB) compromise after provisional stenting of calcified bifurcation lesions treated with rotational atherectomy (RA) or cutting balloon angioplasty (CBA) and the utility of optical coherence tomography (OCT) to detect functionally significant SB stenoses. BACKGROUND The comparative impact of RA versus CBA on SB compromise and functional significance remains poorly characterized. METHODS Seventy-one consecutive patients with 71 calcified bifurcation lesions with angiographically intermediate SB stenoses were randomized to RA (n = 35) or CBA (n = 36). The primary endpoint was SB compromise defined as SB diameter stenosis ≥70%, SB dissection or thrombolysis in myocardial infarction flow grade < 3 after provisional stenting. Secondary endpoints included SB FFR in noncompromised SBs and its correlation with SB ostium area (SBOA) assessed by three-dimensional OCT. RESULTS SB compromise after provisional stenting was observed in 7 (20.0%) lesions that underwent RA and in 9 (25.0%) lesions treated with CBA (p = .62). Mean SB FFR was 0.83 ± 0.08 and was similar between the study arms. Functionally significant SB stenosis (FFR ≤ 0.80) was detected in 17(30.9%) angiographically noncompromised SBs. SBOA after stenting was an independent predictor of FFR ≤ 0.80 (OR 0.002, 95% CI: 0.00-0.15, p = .002). The optimal cutoff value for SBOA to predict functionally significant SB stenosis was 0.76 mm2 (sensitivity 82%, specificity 89% and area under the curve 0.92, 95% CI: 0.84-0.99). CONCLUSIONS The rates of SB compromise and functionally significant stenosis after provisional stenting of calcified bifurcation lesions were similar between two lesion preparation strategies. OCT SBOA can detect SB branches with FFR ≤ 0.80 with high sensitivity and specificity.

Abstract
Coronary bifurcation intervention is common but complex. Progress in this field has been made in recent years with considerable contribution from the Asia Pacific (APAC) region. However, the standard of practice varies across the APAC region due to differences in culture, socioeconomic state and healthcare set-up. Practice may also differ from the rest of the world. Hence, a panel of experts was invited to discuss topics relevant to bifurcation intervention in order to make a concerted effort to achieve consensus that is applicable within the region and in line with available evidence.

JACC Cardiovasc Interv 2020; 12:847-855.

Abstract
OBJECTIVES The aim of the current study was to evaluate the long-term clinical impact of fractional flow reserve (FFR) in jailed left circumflex coronary artery (LCx) after left main coronary artery (LM) simple crossover stenting. BACKGROUND Although the provisional side-branch intervention with FFR guidance has been validated for non-LM bifurcation lesions, the outcome of such a strategy in LM bifurcation disease is not well-known. METHODS Patients who underwent LM-to-left anterior descending coronary artery simple crossover stenting and who had FFR measurements in the LCx thereafter were enrolled. A low FFR was defined as ≤0.80. The clinical outcomes were assessed by the 5-year rate of target lesion failure (TLF) (a composite of cardiac death, target-vessel myocardial infarction, or target lesion revascularization). RESULTS In 83 patients, the mean FFR of the LCx after LM stenting was 0.87 ± 0.08, and 14 patients (16.9%) had a low FFR. There was no correlation between the FFR and angiographic % diameter stenosis in jailed LCx (R2 = 0.039; p = 0.071) and there was no difference in the angiographic % diameter stenosis in the high and low FFR groups. At 5 years, the low FFR group had a significantly higher rate of TLF than the high FFR group (33.4% vs. 10.7%; hazard ratio: 4.09, 95% confidence interval: 1.15 to 14.52; p = 0.029). However, there was no difference in the clinical outcomes according to the angiographic % diameter stenosis. In a multivariate analysis, a low FFR was an independent predictor of the risk for a 5-year TLF (hazard ratio: 6.49; 95% confidence interval: 1.37 to 30.73; p = 0.018). CONCLUSIONS The patients with a high FFR in jailed LCx had better 5-year outcomes than those with a low FFR. The FFR measurement in jailed LCx can be helpful in selecting an adequate treatment strategy and may reduce unnecessary complex procedures.

Abstract
Fractional flow reserve (FFR) is routinely used to determine lesion severity prior to percutaneous coronary intervention (PCI). However, there is an increasing recognition that FFR may also be useful following PCI to identify mechanisms leading to restenosis and the need for repeat revascularization. Post-PCI FFR is associated with the presence and severity of stent under-expansion and may help identify peri-stent-related complications. FFR pullback may also unmask other functionally significant lesions within the target vessel that were not appreciable on angiography. Recent studies have confirmed the prognostic utility of performing routine post-PCI FFR and suggest possible interventional targets that would improve stent durability. In this review, we detail the theoretical basis underlying post-PCI FFR, provide practical tips to facilitate measurement, and discuss the growing evidence supporting its use.

Abstract
BACKGROUND Our study analyzed the relationship between the neointimal strut bridge and jailed side-branch (SB) ostial area in patients with coronary heart disease (CHD) who had a single drug-eluting stent (DES) crossover of the left anterior descending coronary artery (LAD)/diagonal branch (D) bifurcation. PATIENTS AND METHODS A total of 64 CHD patients with an LAD/D bifurcation treated by optical coherence tomography (OCT)-guided single-DES implantation and followed up at 1 year after primary percutaneous intervention (pPCI) were enrolled in our study. According to the two-dimensional OCT results, patients were divided into a non-neointimal bridge group (n = 44) and a neointimal bridge group (n = 20). Basic clinical, angiographic, 2D and 3D OCT, and DES results were analyzed. RESULTS The blood lipid levels of the two groups after the 1‑year follow-up were lower than the levels 1 year earlier (p < 0.05). There was a notable decrease in the SB ostial minimum lumen diameter and area directly after pPCI vs. before pPCI in both groups. The diameter stenosis directly after pPCI showed a clear increase compared with the pre-pPCI value in both groups (p < 0.05 or p < 0.01, respectively). The strut distance of the neointimal bridges in the neointimal bridge group was greater than in the non-neointimal bridge group (p < 0.05). A clearly short strut distance of the neointimal bridge was observed compared with the strut distance of the non-neointimal bridge in the neointimal bridge group (p < 0.05). A larger neointimal bridge area and a smaller SB ostial area were found in the neointimal bridge group compared with the non-neointimal bridge group (p < 0.05 or p < 0.01, respectively). CONCLUSION A short strut distance facilitated formation of a neointimal bridge, which significantly influenced the SB ostial area after single crossover stenting of the SB orifice at the 1‑year follow-up.

Abstract
Coronary bifurcations are involved in 15-20% of all percutaneous coronary interventions (PCI) and remain one of the most challenging lesions in interventional cardiology in terms of procedural success rate as well as long-term cardiac events. The optimal management of bifurcation lesions is still debated but involves careful assessment, planning and a sequential provisional approach. The preferential strategy for PCI of bifurcation lesions remains to use main vessel (MV) stenting with a proximal optimisation technique (POT) and provisional side branch (SB) stenting as a preferred approach. Final kissing balloon inflation is not recommended in all cases. In the minority of lesions where two stents are required, careful deployment and optimal expansion are essential to achieve a long-term result. Intracoronary imaging techniques (IVUS, OCT) and FFR are useful endovascular tools to achieve optimal results.

Abstract
BACKGROUND Bifurcation percutaneous coronary intervention (PCI) remains a challenging frontier in interventional cardiology, especially in the setting of ST-elevation myocardial infarction (STEMI). We examined the procedural and clinical outcomes of this patient subset. METHODS We conducted a retrospective case-control study. Between February 2006 and March 2011, 129 patients with STEMI underwent bifurcation PCI at our institution. One hundred and twenty-nine (129) control STEMI patients with non-bifurcation PCI were selected from the institutional database, matched for age, gender, culprit vessel, and lesion location. Patients with cardiac arrest, cardiogenic shock, or who required mechanical ventilation were excluded. Twelve (12)-month follow-up data were collected by telephone calls and examination of the medical records. RESULTS The average age of patients presenting with STEMI was 61.6 ± 13.1 in the bifurcation group and 61.5 + 31.1 in the non-bifurcation group. There was no difference in lesion type, use of thrombus aspiration catheters, or glycoprotein inhibitors (GPI) among them. Also, the use of drug eluting stent (DES), total cumulative length of stent used, and diameter of the post-dilation balloon were similar. Final kissing balloon post-dilation was performed in 40.3% of bifurcation PCI cases. The incidence of procedural failure (TIMI 0 flow) was 1.5% vs. 0%; p = 0.478. At 12-months follow-up, the bifurcation PCI group had higher incidence of target lesion revascularisation (TLR) (10.9% vs. 3.9%, p = 0.050), mortality (10.1% vs. 2.3%, p = 0.020), and stent thrombosis (9.3% vs. 1.6%; p = 0.013); comprising one acute, nine subacute, and two late vs. two subacute stent thromboses. CONCLUSIONS During acute STEMI, bifurcation PCI has excellent acute procedural outcomes, but significantly increased incidence of TLR, stent thrombosis and mortality at 12 months.

The Relation Between Optical Coherence Tomography-Detected Layered Pattern and Acute Side Branch Occlusion after Provisional Stenting of Coronary Bifurcation Lesions. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2019; 20:1007-1013.

Abstract
BACKGROUND/PURPOSE Layered pattern (presumed to be healed plaque after a thrombotic event) can be observed by optical coherence tomography (OCT). We sought to assess the ability of OCT-detected plaque composition to predict acute side branch (SB) occlusion after provisional bifurcation stenting. METHODS This is a retrospective observational study using pre-intervention OCT in the main vessel to predict Thrombolysis in Myocardial Infarction (TIMI) flow grade ≤1 in a SB (diameter ≥ 1.5 mm) after provisional bifurcation stenting. OCT-detected layered pattern was defined as plaque with a superficial layer that had a different optical intensity and a clear demarcation from underlying tissue. RESULTS Overall, 207 patients with stable coronary disease were included. SB occlusion occurred in 26/207 (12.6%) bifurcation lesions. Operators decided not to perform additional treatment, and TIMI flow did not improve to ≥2 in cases with SB occlusion. The prevalence of OCT-detected layered pattern was more common in lesions with versus without SB occlusion (88.5% versus 33.7%, p < 0.0001); OCT-detected layered pattern was more often located on the same side of the SB (73.9% versus 21.3%, p < 0.0001) circumferentially compared to lesions without SB occlusion. Multivariable analysis showed that OCT-detected layered pattern was an independent predictor of SB occlusion (odds ratio 18.8, 95% confidence interval 5.1-68.8, p < 0.0001) along with true bifurcation lesion and wider angiographic bifurcation angle. CONCLUSIONS The presence of an OCT-detected layered pattern near its ostium was a strong predictor of SB occlusion after provisional bifurcation stenting.

Abstract
Coronary bifurcation lesions account for 15-20% of all percutaneous coronary interventions. Percutaneous revascularization of these lesions is technically challenging and results in lower success rates than nonbifurcation lesions. There are unique procedural considerations and techniques that are employed in the percutaneous revascularization of these lesions. Our objective is to define the procedural complexities of treating coronary bifurcation lesions and describe the leading provisional and dedicated two stent techniques used to optimize procedural and clinical results, as described in the BIFURCAID app.

Abstract
OBJECTIVES To evaluate the impacts of stent techniques on long-term clinical outcomes after percutaneous coronary intervention (PCI) using drug-eluting stents (DES) for coronary bifurcation lesions in patients with or without acute coronary syndrome (ACS). BACKGROUND Few studies have investigated the impacts of stent techniques for treating coronary bifurcation lesions in patients with and without ACS. METHODS This multicenter registry enrolled 2,897 patients undergoing PCI with DES for coronary bifurcation lesions. We investigated the impacts of planned one-stent and elective two-stent techniques in patients with (n = 1,798) and those without (n = 1,099) ACS. Primary endpoint was the incidence of 3-year target-lesion failure (TLF), defined as a composite of cardiac death, spontaneous myocardial infarction, and target-lesion revascularization. RESULTS The planned one-stent technique reduced TLF rate compared to elective two-stent technique in the ACS cohort (hazard ratio [HR] 0.49; 95% confidence interval [CI] 0.34-0.74; P = 0.001), and not in the non-ACS cohort (HR 0.61; 95% CI 0.35-1.06; P = 0.079). After propensity score matching, the planned one-stent technique had a significantly lower TLF rate (HR 0.47; 95% CI 0.29-0.74; P = 0.001) in patients with ACS, and it also showed a trend toward lower TLF rate with the planned one-stent technique in patients without ACS (9.0 vs. 14.5%, HR 0.59; 95% CI 0.32-1.14; P = 0.116). CONCLUSIONS Planned one-stenting reduced TLF in patients with ACS and it also might be beneficial in those without ACS for the treatment of coronary bifurcation lesions.

Abstract
Rotational atherectomy-assisted percutaneous coronary intervention (PCI) on unprotected left main stem (LMS) bifurcation lesions is technically challenging. Intravascular ultrasound (IVUS) has become a standard part of the PCI procedure for the treatment of LMS disease. There is limited experience in performing these cases via a transradial approach using a sheathless guiding catheter (SGC) system. We report a case of a symptomatic octogenarian patient with restrictive angina and significant LMS bifurcation disease, who was successfully treated transradially with the use of the 7.5F Eaucath SGC system and we describe the technical challenges encountered with this strategy.

Abstract
AIMS The aim of this study was to determine the accuracy of the intracoronary electrocardiogram (icECG) to detect ischaemia during bifurcation lesion percutaneous coronary intervention (PCI) with fractional flow reserve (FFR) as a reference. METHODS AND RESULTS Patients with significant bifurcation lesions defined as FFR ≤0.80 were included. FFR and icECG were performed in the main vessel (MV) and side branch (SB) before and after provisional stenting. icECG was recorded with an uninsulated proximal wire end connected to a unipolar lead. The diagnostic accuracy of the icECG for the detection of ischaemia in the SB after MV stenting was determined with FFR as a reference. Overall, 37 patients were included. Seventeen bifurcations had an SB FFR ≤0.80 after MV stenting and 20 patients had an ST-segment elevation on the icECG. There was significant correlation between SB FFR and ST-segment elevation on the icECG (r=-0.533, p<0.001). The diagnostic accuracy of icECG ST-elevation to detect functionally significant SB stenosis revealed an AUC of 0.71 (95% CI: 0.64-0.80) with a sensitivity of 88% and specificity of 75% with a positive predictive value of 75% and negative predictive value of 88%. Neither SB FFR nor icECG correlated with SB percent diameter stenosis after MV stenting. CONCLUSIONS Intracoronary ECG has a good ability to predict functionally significant stenosis at the SB after MV stenting during bifurcation PCI. This method provides a novel strategy to assess the significance of an SB lesion without the need of a pressure wire.

Abstract
INTRODUCTION AND OBJECTIVES To analyze the percutaneous revascularization strategy for severe lesions in the secondary branches (SB) (diameter ≥ 2mm) of major epicardial arteries compared with conservative treatment. METHODS This study analyzed patients with severe SB lesions who underwent percutaneous revascularization treatment compared with patients who received pharmacological treatment. The study examined the percentage of branch-related events (cardiovascular death, myocardial infarction attributable to SB, or the need for revascularization of the SB). RESULTS We analyzed 679 SB lesions (662 patients). After a mean follow-up of 22.2±10.5 months, there were no significant differences between the 2 treatment groups regarding the percentage of death from cardiovascular causes (1.7% vs 0.4%; P=.14), nonfatal acute myocardial infarction (AMI) (1.7% vs 1.7%; P=.96), the need for SB revascularization (4.1% vs 5.4%; P=.45) or in the total percentage of events (5.1% vs 6.3%; P=.54). The variables showing an association with event occurrence on multivariate analysis were diabetes (SHR, 2.87; 95%CI, 1.37-5.47; P=.004), prior AMI (SHR, 3.54; 95%CI, 1.77-7.30; P<.0001), SB reference diameter (SHR, 0.16; 95%CI, 0.03-0.97; P=.047), and lesion length (SHR, 3.77; 95%CI, 1.03-1.13; P<.0001). These results remained the same after the propensity score analysis. CONCLUSIONS The percentage of SB-related events during follow-up is low, with no significant differences between the 2 treatment strategies. The variables associated with event occurrence in the multivariate analysis were the presence of diabetes mellitus, prior AMI, and greater lesion length.

Abstract
The role of final kissing balloon (FKB) inflation after simple crossover stenting in unprotected left main (LM) bifurcation stenosis remains unknown. From the Asan Medical Center-Left Main Revascularization (ASAN-MAIN) registry, 413 patients with LM bifurcation stenosis treated by simple crossover stenting with a drug-eluting stent were identified. After simple crossover stenting, FKB inflation was performed in 95 patients (FKB group) and 318 patients finished the procedure without FKB (no-FKB group). The primary end points of the 2-year incidence of major adverse cardiac events (death, myocardial infarction, and left main target lesion revascularization [LM-TLR]) were similar between the FKB and no-FKB groups (12.5% vs 8.5%, p = 0.24). After adjustment, the risk of major adverse cardiac event was not significantly different between the FKB and the no-FKB groups (hazard ratio [HR] 1.10, 95% confidence interval [CI] 0.49 to 2.49; p = 0.82). The risk of death (HR 1.03, 95% CI 0.28 to 3.82; p = 0.98), the composite of death or myocardial infarction (HR 0.95, 95% CI 0.26 to 3.51; p = 0.96), or LM-TLR (HR 1.32, 95% CI 0.46 to 3.75; p = 0.60) were not significantly different between groups. In conclusions, for the treatment for LM bifurcation stenosis, selective, not mandatory, FKB strategy after simple crossover stenting appears to be associated with a favorable outcome.

Serial changes in the three-dimensional aspect of the side-branch ostium jailed by a drug-eluting stent assessed by optical coherence tomography. Int J Cardiovasc Imaging 2017; 33:797-806.

Abstract
The present study investigated serial changes in the three-dimensional (3D) aspect of the jailed side-branch (SB) ostium. We evaluated 32 patients who underwent examination with optical coherence tomography (OCT) both at baseline and at follow-up. After reconstruction of the 3D images, we classified the configuration of overhanging struts at the SB orifice into three groups according to the 3D aspect of the jailing configuration. The number of compartments divided by the stent strut was counted. The side-branch flow area (SBFA), i.e., the area of the SB ostium except for jailing struts, was measured by cut-plane analysis. Forty-eight SBs of 25 patients were analyzed. Thirteen SBs were classified as the No-jail type (N-type), 19 as the Simple-jail type (S-type; no longitudinal link at the carina), and 16 as the Complex-jail type (C-type; had a link at the carina). In the N-type, the SBFA was significantly increased at follow-up (P = 0.018). In the C-type, the SBFA was significantly decreased at follow-up (P = 0.002). Percent reduction of SBFA in the C-type group was significantly greater than that in the N-type or S-type groups (S-type vs. C-type P = 0.002, N-type vs. C-type P < 0.001). 3D-OCT images showed that some of the compartments were filled with tissue. The number of compartments was significantly decreased at follow-up (P < 0.001). In the C-type group, the SBFA was significantly decreased and small compartments were filled with tissue. These findings suggest that stent jail complexity is associated with the progression of SB ostial stenosis.

Abstract
The objective of this study is to assess 3-year clinical outcome of patients with true bifurcation lesions (TBLs) versus non-true bifurcation lesions (non-TBLs) following treatment with second-generation drug-eluting stents (DES). TBLs are characterized by the obstruction of both main vessel and side-branch. Limited data are available on long-term clinical outcome following TBL treatment with newer-generation DES. We performed an explorative sub-study of the randomized TWENTE trial among 287 patients who had bifurcated target lesions with side-branches ≥2.0 mm. Patients were categorized into TBL (Medina classes: 1.1.1; 1.0.1; 0.1.1) versus non-TBL to compare long-term clinical outcome. A total of 116 (40.4 %) patients had TBL, while 171 (59.6 %) had non-TBL only. Target-lesion revascularization rates were similar (3.5 vs. 3.5 %; p = 1.0), and definite-or-probable stent thrombosis rates were low (both <1.0 %). The target-vessel myocardial infarction (MI) rate was 11.3 versus 5.3 % (p = 0.06), mostly driven by (periprocedural) MI ≤48 h from PCI. All-cause mortality and cardiac death rates were 8.7 versus 3.5 % (p = 0.06) and 3.5 versus 1.2 % (p = 0.22), respectively. The 3-year major adverse cardiac event rate for patients with TBL versus non-TBL was 20.0 versus 11.7 % (p = 0.05). At 1-, 2-, and 3-year follow-up, 6.5, 13.0, and 11.0 % of patients reported chest pain at less than or equal moderate physical effort, respectively, without any between-group difference. Patients treated with second-generation DES for TBL had somewhat higher adverse event rates than patients with non-TBL, but dissimilarities did not reach statistical significance. Up to 3-year follow-up, the vast majority of patients of both groups remained free from chest pain.

Abstract
Heart rate is an established prognostic marker for longevity and is an important contributor in the pathophysiology of various cardiovascular diseases, including ischemic heart disease and heart failure. Most ischemic episodes are triggered by an increase in heart rate, which causes an imbalance between myocardial oxygen delivery and consumption. In addition, increased heart rate is a modifiable risk factor for chronic heart failure. Ivabradine, an inhibitor of If ion channels, is an approved second-line anti-ischemic drug for the treatment of angina. Ivabradine has been shown to decrease the risk of hospitalization in patients with chronic heart failure who were previously treated with β-blockers, renin-angiotensin system blockers or mineralocorticoid receptor antagonists. This review describes the rationale for the pathophysiological and clinical use of ivabradine as an anti-ischemic agent in patients with stable coronary disease and highlights its benefits and drawbacks compared with other first- and second-line anti-anginal drugs. The review also highlights the role of ivabradine as a treatment for patients with high-risk coronary artery disease in whom first-line anti-anginal drugs are insufficient or inadequate and percutaneous coronary intervention is contraindicated or revascularization is incomplete or unsuitable.

Abstract
UNLABELLED INTRODUCTION AND OBJECTIVES Visual angiographic assessment continues to be used when decisions are made on whether to revascularize ambiguous coronary lesions. Multiple factors, other than the degree of stenosis, have been associated with the functional significance of a coronary lesion. The aim of this study was to investigate the ability of interventionists to visually predict the functional significance of a coronary lesion and the clinical and angiographic characteristics associated with errors in prediction. METHODS We conducted a concordance study of the functional significance of coronary lesions predicted by experienced interventionists and fractional flow reserve values measured by intracoronary pressure wire in 665 intermediate lesions (40%-70% diameter stenosis) in 587 patients. We determined which factors were independently associated with errors in prediction. RESULTS There was disagreement between the predicted fractional flow reserve value of ≤ 0.80 and the observed value in 30.1% of the lesions (overestimation: 11.3%; underestimation, 18.8%). Stent location in an artery other than the anterior descending artery or in a bifurcation was associated with overestimation. Male sex, severe calcification, and a greater myocardial territory distal to the lesion were significantly associated with the functional significance of the underestimated lesion. CONCLUSIONS Even when taking into account angiographic and clinical characteristics, there is a high rate of disagreement between visual estimation and direct measurement of intermediate coronary stenosis in relation to its functional significance. Specific angiographic and clinical characteristics are associated with an increased tendency to overestimate or underestimate the significance of lesions.

Abstract
In recent years, a large body of evidence has revealed the limitations of angiographic evaluation in determining the physiological significance of coronary stenosis, particularly when these are intermediate lesions. Percutaneous coronary interventions (PCI) guided by physiological assessment using fractional flow reserve (FFR) have been shown to reduce cardiovascular events when compared to angiography alone. Recently, another coronary physiologic parameter has been introduced: the "instantaneous wave-free ratio" (iFR). In this review, we will discuss the FFR, the iFR, and their use in the functional assessment of coronary stenosis in the cardiac catheterization laboratory. This review will cover theoretical aspects for non-interventional cardiologists, as well as practice points and common pitfalls related to coronary physiological assessment for interventional cardiologists.

Abstract
Coronary bifurcations are involved in 15-20% of all percutaneous coronary interventions (PCI) and remain one of the most challenging lesions in interventional cardiology in terms of procedural success rate as well as long-term cardiac events. The optimal management of bifurcation lesions is, despite a fast growing body of scientific literature, the subject of considerable debate. The European Bifurcation Club (EBC) was initiated in 2004 to support a continuous overview of the field, and aims to facilitate a scientific discussion and an exchange of ideas on the management of bifurcation disease. The EBC hosts an annual, compact meeting, dedicated to bifurcations, which brings together physicians, engineers, biologists, physicists, epidemiologists and statisticians for detailed discussions. Every meeting is finalised with a consensus statement which reflects the unique opportunity of combining the opinions of interventional cardiologists with the opinions of a large variety of other scientists on bifurcation management. The present 11th EBC consensus document represents the summary of the up-to-date EBC consensus and recommendations. It points to the fact that there is a multitude of strategies and approaches to bifurcation stenting within the provisional strategy and in the different two-stent strategies. The main EBC recommendation for PCI of bifurcation lesions remains to use main vessel (MV) stenting with a proximal optimisation technique (POT) and provisional side branch (SB) stenting as a preferred approach. The consensus document covers a moving target. Much more scientific work is needed in non-left main (LM) and LM bifurcation lesions for continuous improvement of the outcome of our patients.

Abstract
OBJECTIVES The aim of this study was to compare the failure rates of crossing side branch (SB) with pressure guidewire vs. coronary guidewire after main vessel (MV) stenting in coronary bifurcation lesions (CBL). BACKGROUND Percutaneous coronary intervention of CBL is technically difficult. The European Bifurcation Club recommends performing either fractional flow reserve (FFR) estimation of the SB or final kissing balloon inflation (FKBI) after the MV stenting when a significant SB ostial stenosis is present. Even though FFR is recommended in CBL, there is concern about SB crossing with pressure guidewire among interventionists. MATERIALS AND METHODS We undertook a comprehensive literature search to identify all relevant studies reporting the failure rates of SB crossing after MV stenting with either pressure or coronary guidewire. A random effects model was used to compare the failure rates between the two approaches. RESULTS Our search identified six studies that reported failure rates of SB crossing with a pressure guidewire (n = 648) and 11 studies that reported failure rates of SB crossing with a coronary guide-wire (n = 2601). Estimated pooled failure rate was 3·9% (95% CI: 1·5% to 9·6%) for inability to cross SB with pressure guidewire. Estimated pooled failure rate of SB crossing with coronary guidewire was 3·1% (95% CI: 1·5% to 6·2%). There was no significant difference between the failure rates in the two groups (P = 0·70). CONCLUSION The failure rates of SB crossing after MV stenting are low with both pressure and coronary guidewire procedures, with no significant difference between the two approaches.

OBJECTIVES The aim of this study was to identify the predictors of side branch (SB) ostial stenosis developed after provisional stenting of the main vessel (MV) using optical coherence tomography (OCT). BACKGROUND Provisional stenting remains the main approach to treatment of bifurcation lesions; however, it may result in the narrowing of SB ostium. There is little information about underlying plaque morphology of the MV lesion and its potential impact on the SB after provisional stenting. METHODS Patients with stable coronary disease with angiographic MV lesion not involving SB were included in a prospective single center study. The primary outcome was significant SB ostium stenosis (SBOS), defined as residual stenosis of >50% after MV stenting. RESULTS Thirty bifurcation lesions in 30 patients were analyzed in the study. Poststenting significant SBOS was observed in 30% of patients. The MV lesions with SBOS > 50% were characterized by a higher prevalence of lipid rich plaques (100 vs. 64%, p = 0.040) and spotty calcifications (60 vs. 0%, p = 0.005). Maximal lipid arcs were greater (257° vs. 132°, p = 0.001) and lipid volume index was higher (1380 vs. 574, p = 0.012) in the SBOS >50% group. Multivariate logistic regression analysis identified maximal lipid arc (odds ratio (OR): 1.014, p = 0.038) and the presence of lipid plaque contralateral to SB ostium (OR: 8.14, p = 0.046) before stenting as independent predictors of significant SBOS after PCI. CONCLUSIONS High lipid content of the MV lesion and a contralateral location of lipid in the bifurcation area may contribute to SBOS after provisional stenting. © 2016 Wiley Periodicals, Inc.

Abstract
OBJECTIVES This study sought to evaluate the optimal percutaneous coronary intervention techniques using drug-eluting stents for bifurcation coronary lesions. BACKGROUND The optimal bifurcation stenting technique needs to be evaluated. METHODS The trial included 2 randomization studies separated by the presence of side branch (SB) stenosis for patients having non-left main bifurcation lesions. For 306 patients without SB stenosis, the routine final kissing balloon or leave-alone approaches were compared. Another randomization study compared the crush or single-stent approaches for 419 patients with SB stenosis. RESULTS Between the routine final kissing balloon and leave-alone groups for nondiseased SB lesions, angiographic restenosis occurred in 17.9% versus 9.3% (p=0.064), comprising 15.1% versus 3.7% for the main branch (p=0.004) and 2.8% versus 5.6% for the SB (p=0.50) from 214 patients (69.9%) receiving 8-month angiographic follow-up. Incidence of major adverse cardiac events including death, myocardial infarction, or target vessel revascularization over 1 year was 14.0% versus 11.6% between the routine final kissing balloon and leave-alone groups (p=0.57). In another randomization study for diseased SB lesions, 28.2% in the single-stent group received SB stents. From 300 patients (71.6%) receiving angiographic follow-up, between the crush and single-stent groups, angiographic restenosis rate was 8.4% versus 11.0% (p=0.44), comprising 5.2% versus 4.8% for the main branch (p=0.90) and 3.9% versus 8.3% for the SB (p=0.12). One-year major adverse cardiac events rate between the crush and single-stent groups was 17.9% versus 18.5% (p=0.84). CONCLUSIONS Angiographic and clinical outcomes were excellent after percutaneous coronary intervention using drug-eluting stents with any stent technique for non-left main bifurcation lesions once the procedure was performed successfully.

Abstract
OPINION STATEMENT Bifurcation lesions are frequently encountered in the cath lab [1] and remain a challenge for conventional percutaneous coronary intervention (PCI) techniques. Although provisional stenting remains the default approach for most bifurcation lesions [2-6], the two-stent technique is more appropriate in certain situations. If a two-stent strategy is selected, then final kissing balloon inflation (KBI) should be performed. Adjunctive assessment with intravascular imaging (intravascular ultrasound (IVUS)/optical coherence tomography (OCT)) and physiologic testing (fractional flow reserve, FFR) should be performed liberally. Drug-eluting stents (DES) are typically utilized to reduce the risk of restenosis in bifurcation disease.
