Pheochromocytoma-Induced Cardiomyopathy Requiring Mechanical Circulatory Support With Cardiac Recovery Following Surgical Resection.

ABSTRACT:

Background

Although exceedingly rare, pheochromocytomas can present with heart failure and cardiogenic shock, leading to complex management considerations.

Case summary

A 49-year-old woman presented with chest pain and palpitations, and ultimately developed cardiogenic shock secondary to a pheochromocytoma. She required Impella 5.5 preceded by Impella CP (Abiomed) and venoarterial extracorporeal membrane oxygenation support as a bridge to surgical resection. After adrenalectomy, she was weaned from mechanical circulatory support, with recovery of left ventricular function.

Discussion

Pheochromocytomas are rare catecholamine-secreting tumors. Patients typically present with episodic headache, sweating, and tachycardia; however, pheochromocytomas can be associated with
