Predictors, treatment, and long‐term outcomes of coronary perforation during retrograde percutaneous coronary intervention via epicardial collaterals for recanalization of chronic coronary total occlusion

Abstract

Retrograde CTO PCI through epicardial collaterals is at increased risk of CP, which is associated with renal dysfunction, RCA CTO, and Epi-CTO score ≥ 2. Prompt and proper management of CP is important. CP is not significantly associated with adverse clinical outcomes.
