Comparison of bare-metal and sirolimus- or paclitaxel-eluting stents for aorto-ostial coronary disease

Abstract

Objectives: Aorto-ostial lesions (AOL) are technically challenging, given their greater propensity to be calcific and associated with elastic recoil compared to non-ostial lesions. This study set out to assess angiographic and clinical outcomes in patients with AOL treated using either paclitaxel-eluting stents (PES) or sirolimus-eluting stents (SES) compared to bare-metal stent (BMS) implantation. Methods: We retrospectively identified 175 consecutive patients with 175 AOL involving the left main, right coronary artery or bypass graft. PES, SES and BMS were implanted in 69, 50 and 56 patients, respectively. Results: Angiographic and procedural success was 100 and 97.1% for PES, 100 and 94% ..
