COMPRARTIVE ANALYSIS OF BIFURCATION STENTING USING "T-PROVISIONAL" AND "MINI CRUSH" TECHNIQUES IN PATIENTS WTIH CHRONIC TOTAL OCCLUSION OF CORONARY ARTERIES
Aim: was to carry out a comparative evaluation of results of stenting of bifurcation lesions in the segment of coronary chronic total occlusions (CTO) using different methods of percutaneous coronary intervention (PCI). Materials and methods: present study is based on results of treatment of 146 patients (2010-2013) with coronary artery disease (CAD), who underwent CTO recanalization and had bifurcation with side-branch diameter more than 2mm. After successful recanalization of CTO, patients were randomized into two groups with respect to the used method of stenting: a group with stenting of major vessel and side branch with technique «Mini Crush», and a group with Provisional «Т-stenting» technique. The primary composite endpoint - incidence of major adverse cardiac and cerebrovascular events (MACCE), which includes thrombosis, restenosis, repeated intervention in the target vessel, acute myocardial infarction, stroke and cardiovascular death. Results: absence of MACCE in the remote period of observation was significantly higher when using and amounted to 87,7% against 63,1% at 12 months after surgery Conclusions: the use of technique «Mini crush» stenting is more effective (to reduce frequency of post-operative complications, risk of restenosis and repeat intervention in long term) in patients with bifurcation lesions in chronic total occlusion of coronary artery in comparison with using «T-provisional» stenting.
