Two-Year Clinical Outcomes with Paclitaxel-Eluting Coronary Stents in Patients with Chronic Total Occlusions: Analysis from the TAXUS ARRIVE Program

Procedural and follow-up outcomes among patients undergoing successful recanalisation of coronary chronic total occlusions using biolimus drug-eluting stents

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 ≥1 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 ≥1 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.
