A Novel, Modified Reverse Controlled Antegrade and Retrograde Subintimal Tracking Technique for Bypassing the Calcified Proximal Cap of Coronary Total Occlusions

<div>Profile of chronic total occlusion (CTO) of the patient. (a) CTO of the proximal right coronary artery (RCA) (right anterior oblique projection). Coronary angiography revealed an anomalous origin of RCA with high anterior take-off from the aorta. (b) CTO of the proximal RCA (left anterior oblique projection). Epicardial collateral channels via the apex from the left anterior descending artery to RCA [right anterior oblique projection (c) and spider projection (d)].</div>
