TCT-760 30-Day Echocardiographic Assessment of Self-Expanding and Balloon-Expandable Valves After Valve-in-Valve Transcatheter Aortic Valve Replacement in Patients With Small Surgical Prostheses

Valve-in-valve (VIV) transcatheter aortic valve replacement (TAVR) is a safe and effective therapy for failed surgical bioprosthetic aortic valves in patients who are at high risk for surgery. Both balloon-expanding valves (BEVs) (Medtronic, Minneapolis, Minnesota) and self-expanding valves (SEVs) (
