Inter- and Intra-Observer Repeatability of Aortic Annulus Measurements on Screening CT for Transcatheter Aortic Valve Replacement (TAVR): Implications for Appropriate Device Sizing

摘要

Objectives:To investigate intra- and inter-observer repeatability of aortic annulus CT measurements for transcatheter aortic valve replacement (TAVR) by readers with different levels of experience and evaluate the impact of different multi-reader paradigms to improve prosthesis sizing.
