Pheochromocytoma Presenting as Severe Biventricular Failure Requiring Insertion of a Biventricular Assist Device

Abstract

CATASTROPHIC CARDIOMYOPATHY resulting from pathologic catecholamine release has been well described in several disease states. Pheochromocytoma, a rare neuroendocrine tumor, can present with acute and profound myocardial depression requiring inotropic support and, in some instances, left ventricular assist device insertion. An unusual case of occult pheochromocytoma presenting as diabetic ketoacidosis (DKA) and biventricular failure, which was then managed with insertion of a biventricular assist device (BiVAD) and, subsequently, surgical resection of the primary tumor is presented.
