Figure 1 Comparison of the Long-Axis View in Control and MVP Patients by TTE and CMR

Control (A to D) and mitral valve prolapse (MVP) (E to H) patients. The two-dimensional transthoracic echocardiography (TTE) parasternal long-axis views (A, B, E, F) and cardiovascular magnetic resonance (CMR) left ventricle (LV) outflow tract views (C, D, G, H). (A, C, E, G) Diastole; (B, D, F, H) systole. In panel H, arrows indicate the prolapsed distance measured by the maximum distance of the prolapsed leaflet to the mitral annular plane. LA = left atrium.
