Abstract:
To improve clinical outcomes after percutaneous coronary interventions of coronary bifurcation lesions, the Tryton Side Branch Stent™ (Tryton Medical, Durham) was developed. Registry studies evaluating the Tryton stent has shown promising clinical results and the stent is currently compared with the provisional single stent strategy in a randomized trial. However, clinical results beyond one year are lacking, and therefore, we investigated the one‐ and two‐year outcomes after Tryton stent placement in a single‐center registry study. Methods and results All patients in our center in whom Tryton placement was attempted between October 2010 and December 2011 were included. Clinical outcomes were defined as cardiac death, any myocardial infarction (MI), target vessel revascularization (TVR), target lesion revascularization (TLR), stent thrombosis (ST), and target vessel failure (TVF; composite of cardiac death, MI, and TVR). Event rates were estimated using the Kaplan‐Meier method. We included 91 patients. Almost half (42%) of the patients included had acute coronary syndrome (ACS) as indication for PCI (12% unstable angina, 14% NSTEMI, and 16% STEMI). Median follow‐up duration was 713 days (IQR 617–840). TVF rates were 14.5% (one year) and 20.3% (two year). Two‐year cardiac death, MI, TVR, TLR and ST rates were 4.4%, 10.2%, 12.7%, 9.2%, and 2.2%, respectively. Conclusions In this single‐center registry, use of the Tryton stent was associated with acceptable clinical outcomes at two‐year follow‐up. © 2013 Wiley Periodicals, Inc.
