A ventricular assist device (VAD) is an electromechanical circulatory device that is used to partially or completely replace the function of a failing heart. The function of VADs differs from that of artificial cardiac pacemakers. Some VADs are intended for short term use, typically for patients recovering from heart attacks or heart surgery, while others are intended for long-term use (months to years and in some cases for life), typically for patients suffering from advanced congestive heart failure.
