Resection of secreting cardiac pheochromocytoma with and without cardiopulmonary bypass.

We report two cases of cardiac pheochromocytoma, the first with superior vena cava obstruction and the second involving the left atrium and extending to the posterior wall of the aorta. Both tumors were resected with disease-free margins, with and without the use of cardiopulmonary bypass, respectively. The patients remain asymptomatic at 8-year and 1-year follow-ups, respectively.
