Use of Left Ventricular Assist Device for Difficult Weaning from Cardiopulmonary Bypass after Surgical Repair of Traumatic Aortic Dissection：A Case Report

Abstract

A 29-year-old man who suffered from traumatic aortic dissection underwent partial arch replacement. He had difficult weaning from cardiopulmonary bypass because of low output syndrome, which was probably due to left ventricular myocardial damage caused by acute aortic valve regurgitation at the onset. To reduce left ventricular load for a middle- to long-term period, we decided to use a left ventricular assist device（LVAD）with ascending aortic perfusion, apex of left ventricle drainage. Three days after surgery, cardiac function gradually improved, and the patient was finally weaned from the LVAD.
