Cardiac pheochromocytoma originating in the interatrial septum.

A 36-year-old woman with classic clinical and biochemical features of pheochromocytoma was found to have a cardiac pheochromocytoma originating in the interatrial septum and a significant obstructive lesion in the left anterior descending coronary artery. Complete resection of the pheochromocytoma and an aortosaphenous vein graft were performed. This is the first reported case of successful resection of an interatrial pheochromocytoma.
