© 2018 Elsevier Inc. Aims: We report the first 5 year clinical follow-up data for the Tryton® bifurcation stent. Methods and results: Clinical outcomes at five years were collected from 8 centres. Non-hierarchical Major Adverse Cardiovascular Events (MACE) and Major Adverse Cerebrovascular and Cardiovascular Events (MACCE) were collected. Diabetic and non-diabetic populations were compared, along with small (≤2.5 mm) vs large (>2.5 mm) side branch size. 173 patients with a follow up rate of 98% at 5 years were analysed. Non-hierarchical MACE was low at 9.8%, consisting of cardiac death of 1.2% (n = 2) and MI of 1.7% (n = 3). Target lesion revascularization (TLR) rate was 6.9% (n = 12). Non-hierarchical MACCE was also low, with major bleeding in 2.3% (n = 4) and strokes in 1.7% (n = 3) of patients. There was only 1 case (0.6%) of stent thrombosis that was definite and occurred very late (782 days). All-cause mortality was low, with 8.7% combined cardiac and non-cardiac death (n = 15). Diabetic patients had significantly higher event rates, but there was no difference in events with lesion stratification by side branch size. Conclusions: The Tryton® Side-Branch Stent has a non-hierarchical MACE of 9.8% and MACCE of 13.9% at 5 years. The TLR was 6.9% with only 1 case of stent thrombosis recorded.
