New Imaging Markers of Clinical Outcome in Asymptomatic Patients with Severe Aortic Regurgitation.

Determining the value of new imaging markers to predict aortic valve (AV) surgery in asymptomatic patients with severe aortic regurgitation (AR) in a prospective, observational, multicenter study. Consecutive patients with chronic severe AR were enrolled between 2015-2018. Baseline examination included echocardiography (ECHO) with 2- and 3-dimensional (2D and 3D) vena contracta area (VCA), and magnetic resonance imaging (MRI) with regurgitant volume (RV) and fraction (RF) analyzed in CoreLab.
