Software-automated multidetector computed tomography-based prosthesis-sizing in transcatheter aortic valve replacement: Inter-vendor comparison and relation to patient outcome

摘要

Background: Correct sizing of the aortic annulus and determination of coronary height is crucial for the efficacy and safety of trans-catheter aortic valve replacement (TAVR). We aimed to compare 3 different software solutions and manual measurements with respect to MDCT-derived annulus sizing parameters, reproducibility and processing time for TAVR planning and to evaluate the impact on patients' outcome.
