The case of a patient undergoing successful resection of an interatria
l septal paraganglioma is presented. The diagnosis of an interatrial m
ass was established preoperatively by echocardiography, ultrafast cine
computed tomographic scan, and cardiac catheterization. The tumor was
excised in total, and the interatrial septum and the roof of the left
atrium were reconstructed using a bovine pericardial patch.
