This study assesses the safety and efficacy of thin-strut stents in non-left main (non-LM) bifurcation coronary lesions.Thinner struts of recent drug-eluting stent (DES) devices are associated with improved outcomes, but data about their performance in challenging scenarios are scant.RAIN was a retrospective multicenter registry enrolling patients with coronary bifurcation lesions or left main (LM) disease treated with thin-strut DESs. Target-lesion revascularization (TLR) was the primary endpoint, while major adverse clinical event (MACE) rate, a composite of all-cause death, myocardial infarction (MI), target-vessel revascularization (TVR), TLR, and stent thrombosis (ST), and its single components were the secondary endpoints. Multivariable analysis was performed to identify predictors of TLR. Outcome incidences according to stenting strategy (provisional vs 2-stent technique), use of final kissing balloon (FKB), and intravascular ultrasound/optical coherence tomography optimization were further investigated in prespecified subanalyses.A total of 1803 patients (59% acute coronary syndrome, 41% stable coronary artery disease) with non-LM bifurcations were enrolled. After a median follow-up of 12 months, TLR incidence was 2.5% (2.2% for provisional stenting and 3.5% for 2-stent technique). MACE rate was 9.4% (all-cause death, 4.1%; MI, 3.2%; TVR, 3.7%; definite ST, 1.1%). After multivariable adjustment, postdilation (hazard ratio [HR], 0.32; 95% confidence interval [CI], 0.15-0.71; P.01) and provisional stenting (HR, 0.62; 95% CI, 0.55-0.89; P=.03) were associated with lower TLR rates. FKB was associated with a lower incidence of TLR in the 2-stent subgroup (P=.03). Intracoronary imaging had no significant impact on the primary endpoint.Thin-strut DES options represent an effective choice in bifurcation lesions. Postdilation and provisional stenting are associated with a reduced risk of TLR. FKB should be recommended in 2-stent techniques. |
