The Evolution of Echocardiographic Type and Anesthetic Technique for Transcatheter Aortic Valve Replacement at a High-Volume Transcatheter Aortic Valve Replacement Center.

Objective: Describe the change in intraoperative transcatheter aortic valve replacement (TAVR) care by examining the utilization of transesophageal echocardiography (TEE) versus transthoracic echocardiography (TTE) and general anesthesia (GA) versus conscious sedation (CS) over time.

Design: Retrospective, observational.

Setting: A university, single, high-volume TAVR center.
