Chronic total occlusion in ostium of right coronary artery - Retrograde approach as the first-choice method of revascularization?

Abstract

Recanalization of chronic total occlusion (CTO) located in the ostium may require the operator's ability to use the retrograde approach. We present a case of opening a chronically occluded right coronary artery (RCA) by the retrograde approach after an unsuccessful attempt of recanalization by classic antegrade technique.
