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

<div>A final angiogram reveals an acceptable outcome. Serial intravascular ultrasound images of right coronary artery (RCA) after stenting show the ostial RCA (a), RCA proximal to chronic total occlusion (CTO) (b), and the CTO segments ((c)–(e)). Images are viewed in a proximal (a) to distal (e) direction. Adequate stent expansion is achieved throughout the lesion, except elliptical stent expansion limited by a superficial calcified lesion at the calcified proximal cap of CTO (c).</div>
