The role of final kissing balloon (FKB) inflation after simple crossover stenting in unprotected left main (LM) bifurcation stenosis remains unknown. From the Asan Medical Center-Left Main Revascularization (ASAN-MAIN) registry, 413 patients with LM bifurcation stenosis treated by simple crossover stenting with a drug-eluting stent were identified. After simple crossover stenting, FKB inflation was performed in 95 patients (FKB group) and 318 patients finished the procedure without FKB (no-FKB group). The primary end points of the 2-year incidence of major adverse cardiac events (death, myocardial infarction, and left main target lesion revascularization [LM-TLR]) were similar between the FKB and no-FKB groups (12.5% vs 8.5%, p = 0.24). After adjustment, the risk of major adverse cardiac event was not significantly different between the FKB and the no-FKB groups (hazard ratio [HR] 1.10, 95% confidence interval [CI] 0.49 to 2.49; p = 0.82). The risk of death (HR 1.03, 95% CI 0.28 to 3.82; p = 0.98), the composite of death or myocardial infarction (HR 0.95, 95% CI 0.26 to 3.51; p = 0.96), or LM-TLR (HR 1.32, 95% CI 0.46 to 3.75; p = 0.60) were not significantly different between groups. In conclusions, for the treatment for LM bifurcation stenosis, selective, not mandatory, FKB strategy after simple crossover stenting appears to be associated with a favorable outcome.
