This study aimed at evaluating the outcome of Biolimus eluting stent (BES) implantation in the treatment of chronic total coronary occlusions (CTO). We identified patients who underwent successful angioplasty for a CTO lesion with ? BES between June 2008 and March 2012. All patients were followed up for major adverse cardiac events (MACE), which comprised death, non-fatal myocardial infarction (MI), cerebrovascular accident, target vessel revascularization (TVR), target lesion revascularization (TLR) and stent thrombosis. 125 patients underwent successful CTO angioplasty with ? Biolimus-eluting stents. Mean age was 63.8?±?12.0?years, and 82.4?% were males. Lesion location was right coronary artery (n?=?80, 64?%), left anterior descending artery (n?=?35, 28?%) and left circumflex artery (n?=?10, 8?%). During follow-up of 579?±?293?days, all cause mortality was n?=?8 (6.4?%) patients, non-fatal MI was n?=?3 (2.4?%), TVR was n?=?3 (2.4?%) and TLR was n?=?1 (0.8?%). Overall MACE was, therefore, n?=?15 (12?%). BES is safe and effective in treatment of CTO lesions, with a low rate of major adverse cardiovascular events during follow-up.
