Transesophageal echocardiographic evaluation of left main coronary artery stent protection during transcatheter aortic valve implantation

摘要

A 94-year-old man with a history of severe symptomatic aortic stenosis, atrial fibrillation, hypertension, and left main coronary artery disease presented for transcatheter aortic valve implantation (TAVI) via the transfemoral approach; written consent was obtained from the patient for presentation of this case. Given his age and comorbidities, a left main coronary stent was placed for his proximal left main coronary disease before TAVI. Technical considerations resulted in the stent protruding into the aortic root at the level of the sinotubular junction.
