Anatomic and functional features of mitral valve. Schematic diagram of the LV outflow tract long-axis view during diastole and systole of bileaflet MVP, showing the main functional and anatomic characteristics during the cardiac cycle. The red double arrow line and white asterisk indicate mitral annular disjunction and bulging of the basal inferolateral segment, respectively. The black double arrow dotted line indicates the PM to anterior annulus distance. The mitral plane both in end diastole and end-systole is indicated y the red lie. These two planes have been superimposed in the insert illustrating the mitral annulus angle (in blue) as the angle between the two. LV left ventricle. PM papillary muscle
