Abstract:
Systematic differences between left ventricular (LV) volumes measured by cardiac magnetic resonance (CMR) and 2D echocardiography have been reported: 2D echo significantly underestimates LV volumes. Mitral regurgitation (MR) due to mitral valve prolapse (MVP) is associated with LV volume overload and remodelling, including increased chamber sphericity. We compared LV volumes in 25 patients (pts) with MVP and at least moderate MR by CMR and echo on 2 different days, 2-4 weeks apart.
