title: Assessment of myocardial function during mechanical left ventricular support using serial echocardiography: a case report.
abstract: A 40-year-old man with valvular heart disease was successfully treated using a left ventricular assist device (LVAD) after open heart surgery. Echocardiography revealed left ventricular ejection fraction (LV-EF) at LVAD on/off: 23.4%/14.6% on the 4th, 23.8%/23.8% on the 5th, and 23.8%/26.8% on the 6th postoperative day (POD), respectively. The patient was weaned from LVAD on the 8th POD and discharged from the hospital on the 58th POD. The LV-EF improved to 54% 6 months after surgery and increased from 57% to 64% in response to exercise stress testing 1 year after surgery.
