Abstract
Prior to transcatheter aortic valve implantation (TAVI), dual-source computed tomography (DSCT) is currently the preferred imaging modality for correct prothesis selection by accurate analysis of aortic annulus and ascending aorta. However, DSCT is associated with the need for contrast administration and radiation exposure.

The potential impact of cardiac magnetic resonance imaging (CMR) and DSCT measurements on TAVI strategy defined by 2D-transesophageal echocardiography (TEE) was evaluated
Annulus diameters assessed by TEE (22.1 ± 2.3mm) were significantly smaller than coronal aortic annulus diameters assessed by CMR (23.4 ± 1.8mm, p
Summary
Prior to transcatheter aortic valve implantation (TAVI), dual-source computed tomography (DSCT) is currently the preferred imaging modality for correct prothesis selection by accurate analysis of aortic annulus and ascending aorta. DSCT is associated with the need for contrast administration and radiation exposure. Purpose This study aimed to compare cardiac magnetic resonance imaging (CMR) with dual source computed tomography (DSCT) for analysis of aortic root dimensions prior to (TAVI). The potential impact of CMR and DSCT measurements on TAVI strategy defined by 2D-transesophageal echocardiography (TEE) was evaluated
