TAMING THE LEAK: SUCCESSFUL COIL EMBOLIZATION OF A DIAGONAL CORONARY ARTERY PERFORATION

Coronary perforation (CP) is a rare but potentially catastrophic complication of percutaneous coronary intervention (PCI). This report describes a Grade 3 perforation in a diagonal branch following lesion preparation with a non-compliant balloon. The perforation was successfully managed with coil embolization, leading to hemodynamic stabilization and preventing further complications. The case highlights the effectiveness of coil embolization as a minimally invasive solution for perforations in small coronary branches when stenting is not feasible, emphasizing the importance of early recognition and intervention in high-risk PCI procedures.
