The First Experience of Using Very Long Stents Covered With Sirolimus (40-60 mm) in the Treatment of Patients With Extensive and Diffuse Lesions of the Coronary Arteries

Objectives. To assess the clinical outcome of one year follow-up in patients with diffuse long lesions treated with extra-long sirolimus-eluting stents. Methods and results. 85 patients underwent implantation of very long BioMime stents during the period from March 2014 to February 2016. Results. The angiographic success rate was 100%, clinical success was observed in 98.8% cases (one patient developed periprocedural MI). The additional back-up support for stent delivery was used in 11 (12.9%) patients (the buddy wire technique in 6 pts and Guidzilla catheter in 2 pts.). Cumulative MACE rate at 12 months was 9.4% with 1.1% myocardial infarction and 5.9% TLR. One patient died 6 month after stent implantation from massive pulmonary thromboembolism. None of the patients had subacute or late stent thrombosis. Follow-up angiography was performed in 48 (68.5%) patients, 5 (10.4%) patients demonstrated restenoses. Conclusion. The use of extra-long sirolimuseluting stents is associated with good procedural and one-year clinical outcomes in complex patients with long and diffuse lesions.
