Abstract 16714: The Effect of Final Kissing Balloon for Treatment of Coronary Bifurcation Lesions in One-Stent Technique
Backgrounds: Final kissing balloon (FKB) has been performed in the percutaneous coronary intervention (PCI) for coronary bifurcation lesions irrespective of one or two-stent techniques. However, there has been a few data on the effect of FKB after one-stent technique for coronary bifurcation lesions.
Methods and Results: One thousand three hundred sixty nine consecutive patients who received PCI for coronary bifurcation lesions were enrolled from 16 centers in Korea from January 2004 to June 2006 in the COronary BIfurcation Stent (COBIS) registry. By operator's choice, 414 (30.2 %) patients were treated with FKB and 955 (69.8%) patients were treated without FKB after one-stent crossover implantation. There were no differences in baseline characteristics between two groups except that acute coronary syndrome was less likely in group with FKB (50.7% vs. 60.9%, p<0.001). Angiographically, group without FKB have more three vessel disease, remote site PCI and higher number of implanted stent (16.5 % vs. 9.7 %, p=0.002, 29.7 % vs. 23.6 %, p=0.028, 1.22 vs. 1.16, p=0.029, respectively), but stent diameter was larger in group with FKB (3.11 mm vs. 3.16 mm, p=0.012). Multivariate cox proportional hazard analysis revealed that PCI without FKB was superior to PCI with FKB in terms of target lesion revascularization (TLR), target vessel revascularization (Hazard ratio (HR 2.721 (95 % confidence interval 1.547–4.786), 2.073 (1.269–3.386), respectively).
Conclusions: When treating coronary bifurcation lesions with one stent crossover implantation, FKB was associated with poor clinical outcome.
