Demonstrates the utility of transesophageal echocardiography in diagnosing a rare biatrial myxoma crossing an atrial septal defect, and its successful surgical management.
Cardiac myxomas are frequently located in the left or right atria, with multiple locations being rare. We report a 59-year-old healthy female with 5 months of cough and exertional dyspnea. A transthoracic echocardiography (TTE) exhibits a 9 × 5 cm nonpedunculated tumor arising from the interatrial septum (IAS) and inhabiting both atria, but was unable to depict the relation with the IAS. Transesophageal echocardiography exposes a single tumor crossing the IAS through an ostium secundum atrial septal defect (ASD) causing right heart functional impairment. Uneventful cardiac surgery allowed complete resection of the lesion and ASD closure. Pathology reported a myxoma.
