Revascularization of Coronary Artery Chronic Total Occlusion by Active Antegrade Reverse Wire Technique.

Objectives: To assess the effectiveness and safety of ARW for vascular recanalization in CTO patients.

Background: Chronic total occlusion (CTO) of coronary artery accompanied with large branch distal to the occluded segment (<2 mm) is one of the challenges physicians are facing during the coronary intervention. In cases where the antegrade wire passed the occluded segment reaching the branch vessel, but could not access the main vessel through various adjustments, application of active antegrade reverse wire technique (ARW) could be considered.
