title: Concomitant complete atrioventricular block and left main coronary artery occlusion during transcatheter aortic valve implantation.
abstract: Transcatheter aortic valve implantation (TAVI) is now considered a viable alternative therapy to surgery in patients with severe symptomatic aortic stenosis, considered to have a high risk for surgery. Herein, we present a case of severe aortic stenosis treated with transfemoral aortic valve implantation and complicated by complete atrioventrciular block and left main coronary artery obstruction that was successfully managed with permanent pacemaker implantation and left main coronary artery stenting. Although less invasive, TAVI can be associated with major complications. Therefore, extra care is required when performing TAVI in patients with borderline valve to coronary ostia distance.
