TCT CONNECT-471 A Novel Computed Tomographic Angiography Tortuosity Index to Predict Successful Sentinel Cerebral Embolic Protection Delivery for Transcatheter Aortic Valve Replacement

Percutaneous transradial placement of the Sentinel (Boston Scientific, Marlborough, Massachusetts) cerebral embolic protection device (CEPD) is indicated during transcatheter aortic valve replacement (TAVR) to capture embolic material in patients without excessive tortuosity of the right subclavian/
