3D parametric models of patient’s mitral valve by the quantification software (QLAB). The mitral valve is viewed from the atrial position with, in grey, the mitral and aortic (Ao) annuli. The yellow dashed line delimits the anterior leaflet, while the dashed blue line delimits the posterior leaflet of the mitral valve. Leaflet colouring in blue hues indicate that the valve is normally located on the LV side of the annulus and red hues indicate the volume of the mitral prolapsing segment. A, anterior; AL, anterolateral; Ao, aortic valve; P, posterior; PM, posteromedial.
