ABSTRACT


BACKGROUND - The optimal strategy to treat bifurcation lesions (BFLs) in a percutaneous coronary intervention (PCI) for chronic total occlusions (CTOs) remains unknown.


AIMS - We sought to assess whether T-provisional or mini-crush is appropriate for BFLs within CTO vessels.


PATIENTS AND METHODS - From January 2011 to December 2013, patients who underwent successful CTO guidewire crossing and with a BFL within the CTO target vessel were enrolled prospectively and assigned randomly to either T-provisional stenting or the mini-crush technique for BFL treatment. One-year clinical follow-up was performed. Major adverse cardiac and cerebrovascular events (MACCE) were defined as the composite of cardiovascular death, myocardial infarction, target vessel revascularization, and stroke.


RESULTS - The prevalence of BFLs was 54.3%. A total of 146 patients with BFLs within CTO vessel were enrolled prospectively and assigned randomly to either T-provisional stenting (N=73) or the mini-crush technique (N=73). Angiographic and clinical success rates were similar in the two groups: 91.8 versus 97.2% (P=0.27) and 91.8 versus 94.5% (P=0.67), respectively.Although T-provisional stenting was associated with a nonsignificantly lower incidence of MACCE in case of BFLs located far from the CTO (9.3 vs. 22.2%; P=0.426), the mini-crush technique resulted in higher MACCE-free survival at 1 year in the presence of BFLs within the CTO body or close to the proximal or the distal cap (89.1 vs. 64.9%; P=0.007).


CONCLUSION - The mini-crush technique appeared to be associated with improved 1-year clinical and angiographic outcomes, particularly when used to treat BFLs located within the CTO body or close to the proximal or the distal cap.
