dc.description.abstractOBJECTIVES: 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.
