We describe the case of an intrapericardial pheochromocytoma located inthe anterior surface of the heart and spreading over the pulmonary trunk.Under cardiopulmonary bypass (CPB) the tumor was removed. "En bloc"resection of the anterior wall of the right ventricular infundibulum andthe pulmonary trunk was performed, with implantation of a fresh aortichomograft in the pulmonary position to avoid free pulmonaryregurgitation.
