Real-time three-dimensional transesophageal echocardiographic imaging of cor triatriatum and persistent left superior vena cava.

The authors describe the case of a 54-year-old woman with the association of two rare congenital cardiac anomalies: cor triatriatum and persistent left superior vena cava with the special characteristic of direct drainage to the right atrium. Real-time three-dimensional transesophageal echocardiography offered a comprehensive anatomic and functional evaluation of these infrequent entities.
