How to select coronary wire for antegrade recanalization of chronic total occlusions

Aim. To define principles of coronary wire choice during coronary artery chronic total occlusion (CTO) recanalization by antegrade approach. Material and methods. From 2009 to 2013 the attempt of coronary artery CTO recanalization by antegrade approach was undertaken for 217 patients. Depending on success of CTO crossing by coronary wire patients were divided into 2 groups: group 1 (n=164) - successful wire crossing, group 2 (n=53) -unsuccessful attempt of CTO recanalization by coronary wire. Results. In the group 2 there were more frequent CTO localization in the right coronary artery (p
