TCTAP A-152 Impact of Final Kissing Balloon Inflation After Simple Stent Implantation for the Treatment of Non-left Main True Coronary Bifurcation Lesions in Patients with Acute Coronary Syndrome

article i nfo Article history: Objectives:We sought to evaluate the impact of final kissing balloon inflation (FKBI) after simple stent implantation for the treatment of non-left main true coronary bifurcation lesions in patients with acute coronary syndrome (ACS). Background: Whether FKBI should be mandatory after simple stent implantation for the treatment of coronary bifurcation lesionis controversial. Besides, ACS patientswho have undergone bifurcation percutaneous coronary interventionwithsimplestentimplantationmayexperienceworseprognosiscomparedtostableanginapectoris patients. Methods: Two hundred and fifty one eligible patients (67.7% male, mean age 61.7 ± 10.4 years) were enrolled. The study population was divided into two groups according tothe performance of FKBI. The primary end points were major adverse cardiac event (MACE); target lesion revascularization (TLR), non-fatal myocardial infarction (MI) and cardiac death during the follow-up period. Results: Over a mean follow-up period of 3.0 ± 1.9 years, there were 29 MACEs (10 TLR, 6 non-fatal MI, and 13 cardiacdeaths),representinganeventrateof11.6%.Kaplan-MeiersurvivalanalysisrevealedthatFBKIgrouphad favorable outcome compared to non-FKBI group with regard to hard events (p = 0.010) as well as composite MACEs (p = 0.008). In multivariable analysis, FKBI was a significant predictor of composite MACEs (hazard ratio 0.398 (95% confidence interval 0.190-0.836, p = 0.015)) and hard events (hazard ratio 0.325 (95% confi- dence interval 0.130-0.811, p = 0.016)). Conclusions: In terms of prognosis, performing FKBI after simple stent implantation for the treatment of non-left main true coronary bifurcation lesions may be mandatory in ACS patients. © 2014 The Authors.
