Zusammenfassung
Introduction: Transcatheter aortic valve implantation (TAVI) is an increasingly used treatment option for patients with severe aortic valve stenosis but high risk of conventional surgery. Prosthesis sizing is critical for procedural success. The size of the aortic annulus in echocardiography is routinely used for prosthesis sizing, but CT can provide accurate visualization of the aortic valve apparatus and may be a better modality to determine its dimensions. However, the correlation of CT-based measures of the aortic annulus to echocardiography is not well known. Methods: 86 patients scheduled for TAVI were inv…
