Lithoplasty-Facilitated Proximal Cap Penetration of a Calcified Chronic Total Occlusion Coronary Lesion.

We present a case of calcified chronic total occlusion of the left anterior descending coronary artery with ambiguous cap at the bifurcation with a large diagonal branch, in which intravascular lithoplasty balloon was used to modify the calcified proximal cap and facilitate wire crossing. (Level of Difficulty: Advanced.).
