Objectives To assess the long‐term clinical outcomes associated with treatment of nonleft main coronary bifurcation lesions using a modified provisional jailed‐balloon technique (JBT). Background Percutaneous coronary intervention (PCI) of bifurcation lesions is associated with a higher risk of adverse events, including the risk of side branch (SB) loss during main branch (MB) stenting. Methods From 4/2003 to 8/2010, 406 patients with 424 nonleft main coronary bifurcation lesions underwent PCI with ( n = 95) and without ( n = 311) the use of JBT. Rates of SB loss and long term clinical outcomes [death, myocardial infarction (MI), and target lesion revascularization (TLR)] were compared between patients undergoing PCI with and without JBT using univariate and propensity score adjusted and matched analyses. Results The majority of patients presented with acute coronary syndrome (63%) and 90% of lesions were Medina class 1,1,1. Patients were followed for a mean of 2.7 ± 2.1 years. After propensity score matching ( n = 81 in each group), JBT was associated with a significantly lower composite rate of death, MI, or TLR (HR 0.22, 95% CI 0.06–0.76; P = 0.02) and TLR (HR 0.20, 95% 0.04–0.92; P = 0.04) compared with no JBT. Permanent SB loss was significantly lower in the JBT group compared with no JBT group (OR 0.22, 95% CI 0.10–0.49; P = 0.0001). Conclusions The use of JBT for the treatment of nonleft main coronary bifurcation lesions was associated with significantly lower rates of SB loss and major adverse cardiac events at late follow‐up. © 2013 Wiley Periodicals, Inc.
