“…However, regarding conventional QCA for the MV in our study, it has been reported that the %DS of the MV is inversely correlated with the FFR value, whereas the %DS of the SB determined by conventional QCA was unreliable and not correlated with physiological ischemia assessed by FFR. 40 Fourth, no stent thromboses were seen in either the FKB or the no-FKB groups. This can potentially be explained by: (1) the low sample size used to detect stent thrombosis; (2) exclusion of complex lesions from the study population (ie, 2-stent strategy and long stenting); and (3) high use of IVUS.…”

110YAMAWAKI M et al. Circulation JournalOfficial Journal of the Japanese Circulation Society http://www. j-circ.or.jp oronary bifurcation has been regarded as one of the most challenging lesion subsets due to poor clinical outcomes compared with non-bifurcated lesions. 1 Provisional intervention of the side branch (SB) after main vessel (MV) stenting is now the standard approach for most bifurcations. 2,3 Although the final kissing balloon technique (FKB) has been established as the first-line strategy for bifurcations treated with an elective 2-stent approach, 4,5 its efficacy in a 1-stent approach is presently under debate. 6,7 Randomized trials showed no benefit of FKB in a 1-stent approach; 8,9 however, the long-term clinical outcome remains unclear as limited data is currently available. 6,10 The purpose of the present study is to: (1) investigate the long-term outcomes after a 1-stent approach with and without FKB; and (2) to ascertain the clinical outcome after cross-over stenting without FKB in comparison with non-bifurcation patients. MethodsThis study is a sub-analysis of the TAXUS Japan Postmarket Surveillance Study (TAXUS-PMS), which evaluated the safety and performance of a paclitaxel-eluting stent (PES; TAXUS

“…Bifurcation angle was defined as the angle between the distal MV and the SB at its origin using the angiographic projection with the widest separation of the two branches [5]. For quantitative coronary angiographic (QCA) analysis of a total of 8 segments, bifurcation lesions were divided into the proximal reference, MV proximal (proximal to SB take-off), MV middle (<5 mm distal to take-off), MV distal, MV distal reference, SB ostial (<5 mm distal to take-off), SB distal and SB reference segments (fig.…”

Objectives: Bifurcation angle has emerged as a predictor of outcome after percutaneous coronary intervention (PCI) for bifurcation lesions. We investigated the impact of bifurcation angle on clinical outcomes in patients undergoing bifurcation lesion PCI. Methods: Consecutive patients who received PCI for bifurcation lesions were enrolled from 16 centers in Korea between January 2004 and June 2006. Patients were divided into low-angle and high-angle groups using the median bifurcation angle (50°). We compared major adverse cardiac events, including cardiac death, myocardial infarction and target lesion revascularization as well as periprocedural outcomes between the 2 groups. Results: We evaluated 1,432 patients with bifurcation lesions with a median follow-up duration of 21 months. The rates of interventional side branch procedures such as guide-wiring of side branches, side-branch ballooning, final kissing ballooning and side-branch stenting were higher in the low-angle group. However, the incidences of major adverse cardiac events and target lesion revascularization were not significantly different between the 2 groups (6.6 vs. 6.9%, p = 0.856 and 4.6 vs. 5.7%, p = 0.375, respectively). Conclusions: Bifurcation angle may not influence long-term clinical outcome in patients with non-left main bifurcation lesion undergoing PCI despite its association with more interventional side-branch procedures.
