Left Main Coronary Artery (LMCA) Iatrogenic Dissection: A Case Report of a Catastrophic Complication During Primary Percutaneous Coronary Intervention (PCI).

Catheter-induced coronary artery dissection is a rare and serious complication that may occur during coronary angiography or angioplasty procedures. Its timely recognition and appropriate management are critical to prevent severe consequences such as myocardial infarction or sudden cardiac death. The treatment strategy depends on the extent and location of the dissection, with revascularization often required to restore adequate coronary blood flow. Various approaches, including percutaneous intervention, may be employed based on the clinical scenario. In this report, we describe a case of successful recanalization following an iatrogenic coronary dissection, emphasizing the importance of early intervention and individualized management.
