ABSTRACT


AIMS - Previously, we reported that the nine-month angiographic result after treatment of coronary bifurcation lesions with provisional T-stenting was not significantly different from that with routine T-stenting. To compare long-term clinical outcomes of the two stenting strategies, we extended the follow-up of our study on bifurcation stenting.

 

METHODS AND RESULTS - One hundred and one patients with coronary bifurcation lesions had been randomly assigned to provisional T-stenting and 101 to routine T-stenting, using sirolimus-eluting stents. We performed complete five-year follow-up. The primary efficacy endpoint was the incidence of target lesion revascularisation (TLR), and the primary safety endpoint was the incidence of definite/probable stent thrombosis (ST). We also monitored death, myocardial infarction (MI) and MACE (composite of death, MI and TLR). The cumulative five-year incidence of TLR in the provisional T-stenting arm was not significantly different from that in the routine T-stenting arm (16.2% vs. 16.3%, p=0.97). The same was true for MACE (22.8% vs. 22.9%, p=0.91), the composite of death and MI (9.9% vs. 13.9%, p=0.40), and ST (2.0% vs. 5.1%; p=0.25).

 

CONCLUSIONS - During five-year follow-up, routine T-stenting offered no advantage over provisional T-stenting with respect to TLR or MACE. ClinicalTrials.gov Identifier: NCT00288535
