Aortic regurgitation severity after transcatheter aortic valve implantation is underestimated by echocardiography compared with MRI

Abstract

Using CMR for the quantification of AR in a sizeable group of TAVI patients, we demonstrate a strong tendency of TTE to underestimate AR compared with CMR. Since higher AR severity on echocardiography has been associated with worse patient outcome, the potential incremental prognostic value of CMR should be studied prospectively in this setting.
