Angiogram of the month Successful rescue of a perforated chronic total occlusion using retrograde technique

Abstract

Percutaneous coronary intervention of chronic total occlusion (CTO) is one of the greatest challenges in coronary interventions. Retrograde wiring is suggested as a solution to improve the success rate of intervention for CTO. We experienced the coronary perforation during antegrade wiring at the CTO lesion and sealed it using retrograde wiring and antegrade stenting in a patient who underwent coronary arterial bypass grafting. We found that, in selected cases, the retrograde wire technique may provide a valuable rescue option for perforated CTO in a patient having a retrogradely accessible conduit vessel.
