title: Double-orifice mitral valve with three papillary muscles.
abstract: A case of double-orifice mitral valve in a 16-year-old Japanese boy is presented. Two-dimensional echocardiography, including transesophageal approach, showed two approximately equal orifices with three papillary muscles. Color Doppler echocardiography showed a mild mitral regurgitation from both orifices. No other cardiac anomaly was associated. The patient's left ventricular function is presently normal.
