Coronary bifurcation stenting with dedicated Tryton side-branch stent. Early and 6-month results of 40 patients

Abstract

Backgroud: Coronary artery bifurcation stenting using standard stents is associated with increased risk of complications and poor long-term prognosis. Bifurcation-dedicated stents raise a hope of improving the acute and late results of such procedures. Aim: To assess the early and mid-term results of bifurcation stenting with the specially designed bifurcation-dedicated Tryton side-branch stent. Methods and results: We evaluated 40 consecutive procedures of coronary artery bifurcation stenting using a Tryton stent in patients with stable angina or acute coronary syndrome without ST elevation. The stent was successfully implanted in 39 patients. The main vessel was treated with drug-eluting stents in 38 cases, whereas bare metal stents were used in the remaining two. In one case the procedure was complicated by non-Q wave myocardial infarction. During 30-day and 6-month observation no additional major adverse cardiac events were observed. Conclusion: Coronary bifurcation stenting with the Tryton side-branch stent is highly effective, with a low rate of acute and midterm complications.
