Iatrogenic Left Main Coronary Artery Dissection During Non-Left Main Intervention: A Case Series

Abstract

Iatrogenic left main coronary artery (LMCA) dissection is a rare complication of percutaneous coronary intervention (PCI), it is mainly attributed to the catheter-based manipulation during engagement of Ostia or during the intervention. LMCA dissections are very dynamic ranging from a small, stable, and localized tear to extensive dissection obstructing coronary branches and cardiac arrest. Without prompt intervention, it often is a fatal complication. In this case series, we report three cases of LMCA dissection and their management with intravascular ultrasound-guided PCI.
