Fig. 15.1 LV remodeling causing PLPM displacement and leaflet tethering, resulting in FMR While the Myosplint was undergoing clinical trials in Europe, it was observed that the Myosplint chord placed…
Fig. 5.1 Biplane Mode (X-plane) acquisition with 3D transoesophageal echocardiography. Left side panel: the reference plane is mid-oesophageal four chamber view. Right side panel: 2D image of the mitral valve…
Fig. 16.1 Schematic representation of the force balance on the mitral leaflets. Increased tethering forces from a dilated left ventricle oppose the force of transmitral pressure which acts to close…
Fig. 8.1 Schematic of the mechanism underlying ischemic (functional) mitral regurgitation; see text for details. Ischemic LV distortion results in papillary muscle displacement, leaflet tethering and annular dilation. This restricts…
