Two-dimensional color Doppler and transesophageal echocardiography revealed complete absence of the posterior mitral leaflet, a thick muscular formation replacing the posterior leaflet, a 3.3-cm secundum type atrial septal defect, and severe pulmonary hypertension. This report describes the rare case of congenital absence of posterior mitral leaflet associated with secundum type large atrial septal defect in a middle-age woman.
