Predilation of branch vessels with dual wire balloon or conventional balloon during percutaneous coronary intervention in treating bifurcation lesions of coronary artery: comparison analysis of safety and efficacy
Abstract：Objective To evaluate the safety and efficacy of predilation of branch vessels with dual wire balloon or conventional balloon during percutaneous coronary intervention (PCI) with simple strategy in treating bifurcation lesions of coronary artery.Methods Totally 162 patients with 170 bifurcation lesions of coronary artery confirmed by coronary angiography who underwent PCI with simple strategy from Janunary 2011 to Janunary 2014 retrospectively analyzed.During PCI,the branch vessels were predilated with dual wire balloon (DB group,78 cases) or conventional balloon (PB group,84 cases).The procedural success rate of PCI and percutaneous transluminal coronary angioplasty (PTCA),involvement of branch vessel,complications and incidence of major adverse cardiac events (MACEs) were compared between the two groups.Results The clinic characteristics,site and Duke classification of bifurcation were not significantly different between the two groups (P ＞ 0.05).The procedural success of PCI for the main vessels was 100％ (84/84) in DB group and 97.7％ (84/86) in PB group,without significant difference (P ＞ 0.05),but the procedural success rate of PTCA for branch vessels in DB group was significantly higher than that PB group [94.0％ (79/84) vs 81.4％ (70/86)] (P ＜ 0.05).The incidence of perioperative myocardial infarction in DB group was significantly lower than that in PB group [5.1％ (4/78) vs 17.9％ (15/84)] (P ＜ 0.05).During 12-months of follow-up,the incidence of MACEs in DB group was significantly lower than that in PB group [6.7％ (5/75) vs 15.0％ (12/80)] (P＜0.05).Conclusion During PCI with simple strategy in treating bifurcation lesions of coronary artery,it is safe and effective to pre-dilate the branch vessels with dual wire balloon,with higher success rate and less complications compared with conventional balloon.
