INTRAPERICARDIAL PHEOCHROMOCYTOMA

Pheochromocytoma are catecholamine-secreting tumors occurring in less than 1% of the hypertensive population. Even though more sensitive met hods have facilitated the diagnosis of intrathoracic paragangliomas th ey still remain extremely rare, This study reports a patient with a ca rdiac pheochromocytoma in whom the tumor was located on the outside of the roof of the left atrium and involved the left main coronary arter y, Due to this anatomy the resection of the tumor required a cardio-pu lmonary bypass and transsection of the pulmonary artery, The postopera tive course was uneventful and the patient could be discharged without significant hypertension.
