Retrograde balloon crossing to overcome antegrade delivery failure for a heavily calcified chronic total occlusion.

ABSTRACT: We herein report a case of percutaneous coronary intervention to a heavily calcified chronic total occlusion in the left anterior descending artery. Although we successfully performed retrograde wire crossing and wire externalization, we were unable to deliver small-sized balloon catheters in the lesion antegradely, even with strong back-up of wire externalization because of the heavy calcium mass. However, a balloon catheter was easily crossed retrogradely, and the lesion was successfully treated. Thus, retrograde balloon crossing might be a way to overcome device delivery failure in calcified lesions. <Learning objective: Dense calcium often prevents devices from passing through a chronic coronary total occlusion. In the present case, retrograde delivery through an epicardial coll
