title: Counterpulsation with a new pulsatile assist device (PAD) in open-heart surgery.
abstract: A new pulsatile assist device that converts roller pump flow to pulsatile flow has been developed and proven effective through clinical testing. The PAD is also a hemodynamically effective arterial counterpulsator both before and after cardiopulmonary bypass. The PAD has been found to be an important adjunct to the care of critically ill patients undergoing open-heart surgery. In addition, in selected patients, the PAD is a reasonable alternative to the elective use of intra-aortic balloon pumping.
