Infected biatrial myxoma: transesophageal echocardiography-guided surgical resection.

We identified a biatrial myxoma using transesophageal echocardiography whose right atrial component was missed with conventional transthoracic techniques. Identifying the biatrial component directs a safer approach to right heart catheterization. Infected biatrial myxomas are both rare and successfully managed using prolonged intravenous antibiotic therapy followed by resection. Atrial septal defects created during the resection of an infected myxoma may be safely repaired using a prosthetic patch.
