Key Points 1. An ultrasound beam is a continuous or intermittent train of sound waves emitted by a transducer or wave generator that is composed of density or pressure. Ultrasound waves are characterized by their wavelength, frequency, and velocity. 2.…
Key Points 1. Intraoperative transesophageal echocardiography (TEE) plays a valuable role in interventional cardiac procedures, when used to guide transseptal puncture, evaluation of left atrial thrombus, closure of paravalvular leaks, transcatheter valve deployment, and during removal of transvenous lead extractions.…
