Crush Stenting With Paclitaxel-Eluting or Sirolimus-Eluting Stents for the Treatment of Coronary Bifurcation Lesions

Abstract

Two hundred forty-six patients with 252 bifurcation lesions were enrolled into a prospective, nonrandomized study to use paclitaxel-eluting or sirolimus-eluting stent for crush stenting in the treatment of coronary bifurcation lesions. Compared with the sirolimus-eluting stent group, the paclitaxel-eluting stent group had significantly higher mean late lumen and binary angiographic restenosis rates. Sirolimus-eluting stent versus paclitaxel-eluting stent recipients had significantly lower in-segment restenosis in the entire main vessel (15.7% vs 3.1%, P = .004), and simultaneous side branch and main vessel restenoses were solely detected in the paclitaxel-eluting stent group (11.9% vs 0%, P = .03). Target-lesion vessel revascularization and cumulative major adverse cardiac events rates were significantly higher in the paclitaxel-eluting versus the sirolimus-eluting stent group (17.99% vs 8.41%, P = .01; 19.4 vs 9.3%, P = .01; 23.6 vs 11.2%, P = .03). In this study with crush stenting, use of sirolimus-eluting stent, compared with paclitaxel-eluting stent, yielded significantly lower late lumen loss, restenosis, and revascularization rates, with comparable safety by 8-month follow-up.
