Unique Identifier : AIDSLINE MED/95167573 AB Measurement of the areas of the cusps and leaflets of the left atrioventricular valve (LAV) and a study of their shape were performed in 91 normal human hearts, to assess the range of variation and determine the most frequent morphologic pattern. The average areas were as follows: LAV, 904.9 mm2; anterior cusp, 447 mm2; posterior cusp, 457 mm2; anterolateral leaflet, 118.6 mm2; intermediate leaflet, 212.7 mm2; and posteromedial leaflet, 126 mm2. The commonest shape of the leaflets of the posterior cusp, proved to be rectangular.
