Resumen
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 mm(2); anterior cusp, 447 mm(2); posterior cusp, 457 mm(2); anterolateral leaflet, 118.6 mm(2); intermediate leaflet, 212.7 mm(2); and posteromedial leaflet, 126 mm(2). the commonest shape of the leaflets of the posterior cusp, proved to be rectangular.
