Abstract
Our analysis shows that CMR and CT measurements of aortic geometry show good agreement, including measurement of annulus size and coronary artery location, and thus provide the necessary anatomical information for valve-in-valve TAVR planning. However, in patients with metal strut aortic valve constructions, CT should be performed due to the presence of limiting metal artefacts on CMR. CMR may be considered as an appropriate alternative to CT in patients in whom iodinated contrast agents are contraindicated or where additional haemodynamic assessment with phase-contrast CMR is required.
