title: Real time three-dimensional transesophageal echocardiography imaging of crescent-shaped superior sinus venosus atrial septal defect.
abstract: Multi-imaging modalities should be considered in patients with atrial septal defects (ASDs) in which the degree of right ventricular enlargement is not fully explained by the small size of ASD found on conventional transthoracic echocardiography. We report a case of crescent-shaped superior sinus venosus ASD discriminated using real-time three-dimensional transesophageal echocardiography. MDCT confirmed its relationship with the superior vena cava and the absence of combined anomalies, such as the pulmonary venous return anomaly.
