[Double orifice mitral valve. Study with two-dimensional echocardiography].
Double orifice mitral valve is a rare congenital anomaly which is frequently associated with atrioventricular defects. According to its structure it is classified as central, commissural or valvar. Diagnosis by cross-sectional echocardiography was verified in 4 patients with a double orifice mitral valve of the central type. Age of the patients at the time of diagnosis ranged from 3 months to 17 years. Three of them had an associated ostium primum atrial septal defect. The defect was observed in parasternal long-short axis views and subcostal 4 chamber axis views. The parasternal short axis gave information on the central type but subvalvular structures of the double orifice and insertion of the chords in papillary muscle were best observed in parasternal long and subcostal four chamber axis views.
