摘要

A 37-year-old male patient was admitted to our service for end-stage heart failure secondary to ischemic cardiomyopathy. He was listed for heart transplantation (HTx) and due to declining hemody-namic status (Intermacs Profile-2) was subsequently implanted with a pulsatile paracorporeal system (EXCOR VAD, Berlin Heart GmbH, Berlin, Germany) for left ventricular support. Postoperative follow-up was uneventful until the seventh postoperative month, when the patient called the hospital and reported that the device was alarming. He had no clinical symptoms, and his hemodynamics were stable. The pump was alarming with a "low pump output" signal. Transthoracic echocardiography demonstrated sufficient left ventricular unloading and no inflow or outflow cannula obstruction. The EXCOR pump chamber, the power supply, and the cables of the pump were intact and functional, and no sign of incomplete ejection was evident by visual examination.
