Figure 1 Benefits of myectomy in widening left ventricular outflow tract (LVOT) diameter (A), of longer neochordae for further extension of left ventricular outflow tract diameter (B), and of neochordae for correction of mitral regurgitation by relocating anterior mitral leaflet (AML) toward annular plane (C). AV, Aortic valve; LA, left atrium; PML, posterior mitral leaflet; IVS, interventricular septum; LV, left ventricle.
