Acute left main coronary artery occlusion following transcatheter aortic valve replacement without obvious risk factors of coronary obstruction

Transcatheter aortic valve implantation (TAVI) has emerged as a prominent alternative for patients with severe aortic stenosis, who are deemed to be at a greater risk for surgical interventions (1). However, extreme caution is recommended against the lethal complications, such as coronary obstruction (CO) or annulus rupture, associated with this procedure that need to be overcome urgently (1). Herein, we report an occlusion of acute left main coronary artery (LMCA) after TAVI, which was treated with triple stenting, due to immediate stent recoils.
