Retrograde Percutaneous Coronary Intervention to Acute Left Main Occlusion After Transcatheter Aortic Valve...

Coronary obstruction (CO) represents a rare yet critical complication following transcatheter aortic valve replacement (TAVR), characterized by significant mortality and morbidity. Computed tomography plays a pivotal role in the pre-procedural assessment and prediction of this risk. While various techniques have been devised to mitigate the occurrence of CO, management of such complications remains challenging with few available treatment options. Herein, we present a case involving left main CO that was successfully managed through retrograde angioplasty and stenting utilizing a saphenous venous graft.
