摘要

Background: ?Treatment of coronary bifurcation lesions using a single stenting strategy is preferable over that using a 2-stent technique. The benefit of final kissing inflation (FKI), however, has not been established. Methods and Results: ?Seventy-two patients (76 lesions) with true bifurcation lesions treated with a single drug-eluting stent with FKI (n=33 lesions) or without FKI (non-FKI, n=43 lesions) were enrolled in this study. Optical coherence tomography (OCT) was performed at 6–12 months after implantation. Based on the OCT findings, the percentage of jailing struts (number of jailing struts/total number of struts at the bifurcation lesion) was calculated. Percentage of uncovered struts and frequency of thrombus attachment were each evaluated at the proximal, bifurcation, and distal segments. Major adverse cardiac events (MACE) were also evaluated. The percentage of jailing struts was significantly lower in the FKI than in the non-FKI group (5.8±6.2% vs. 17.3±6.1%, P
