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

<div>(a) A chronic total occlusion (CTO) in the right coronary artery. (b) A Gaia Third guidewire (Asahi Intecc) is retrogradely advanced into the subintimal space past the CTO ostium. (c) An antegrade balloon-assisted subintimal reentry is performed, which is created proximally to the occluded segment using a large balloon. (d) The retrograde guidewire successfully penetrated the proximal true lumen.</div>
