Surgical resection of intracardiac gastrinoma

There has been only one previous report of an intracardiac gastrinoma causing Zollinger-Ellison syndrome. In this communication we describe the successful surgical resection of a gastrinoma located in the interventricular septum using cardiopulmonary bypass, blood cardioplegia, and mild hypothermia. Preoperative evaluation and histologic examination of the resected tumor strongly suggest that this was a primary intracardiac gastrinoma.
