Premises – Left main coronary artery disease is the highest-risk lesion subset of ischemic heart disease, and has traditionally been an indication for coronary artery bypass grafting. In recent years, many interventional techniques have been proposed for the treatment of such lesions. Implantation of self-apposing stents is one of them. These stents have a conical shape and open cells, which allows us to restore the bifurcation of left main and achieve anatomy close to the physiological. Material and methods – Thirty-three patients with left main bifurcation lesions treated with self-apposing coronary, nitinol, sirolimus-eluting stent using stent with balloon technique were enrolled in this study. These patients were admitted in hospital during 2016. Primary endpoints were a procedural success, defined as favourable technical and angiographic result in the absence of a major adverse cardiac event (MACE) at hospital discharge and cumulative MACE at six months follow-up. Results – Post-procedural TIMI III flow was reached in both vessels. One recorded stent with balloon technique failure (3.0%) was attributed to impossibility of rewiring due to extremely tortuous circumflex artery, and calcified ostium. There were 2 patients (6.1%) with in-stent thrombosis during hospitalisation and 2 patients (6.1%) with in-stent restenosis during six-month follow-up after intervention. All these events were confirmed angiographically. The cumulative MACE at six-month rate was 12.0% (p[removed]
