Bifurcation lesions make up 15-20% of all treated coronary lesions. Despite impressive advances in interventional cardiology, their treatment has been associated with technical challenges and rather poor clinical efficacy. The main recommended strategy in the treatment of these lesions is "provisional stenting", with a double-stent technique to be possibly considered as an alternative. In our registry, we decided to assess the safety, technical and clinical success rates in the treatment of these lesions using the dedicated Tryton Side Branch bifurcation stent. The registry included 201 patients of an unselected population considered for treatment using the Tryton bifurcation stent at the Cardiovascular Center of the Liberec Regional Hospital from June 2012 through April 2016. The success rate of bifurcation lesions treatment with the Tryton stent was 85.07%. The patients were subsequently followed up for six months since the procedure. Three patients experienced a myocardial infarction, with only three patients requiring revascularization, and no need to treat the culprit artery or lesion in a single case. The question of bifurcation lesion treatment remains open; an alternative strategy in these patients seems to be the use of dedicated bifurcation stents. The advantage of the Tryton bifurcation stent is that it protects the side branches, whose treatment may pose a problem with most standard techniques. Judging by our data, the Tryton stent can be employed with advantage especially in bifurcation lesions in large side arteries (≥ 2.5 mm). Overall, data from our registry support the device's very good safety profile and success rate in the treatment of this type of bifurcation lesions using the Tryton stent.
