Right Ventricular Dysfunction/Failure After
Implantation of a Left Ventricular Assist Device
|SynCardia Comments: Most mechanical circulatory support (MCS) devices augment blood flow through the failing ventricle(s). While these devices may reduce the patient's symptoms and slow the progression of heart failure, they do not stop it. Many professional papers have documented the incidence of right ventricular dysfunction/failure after implantation of a Left Ventricular Assist Device (LVAD). Definitions of right ventricular dysfunction and failure vary by paper.
Similar to a heart transplant, the SynCardia temporary Total Artificial Heart replaces both failing heart ventricles and the four native heart valves. It is the only device that eliminates the symptoms and source of biventricular failure.
