Directions in cardiac assistance.
The use of mechanical circulatory support devices came to prominence with the use of the Jarvik 7 total artificial heart, both as a permanent implant and as a bridge to transplantation. Over the past decade, however, interest in the use of left ventricular assist devices has overshadowed that of the total artificial heart and great strides have been made, both in the use of such devices as temporary support, and towards the ultimate goal of permanent implantation. A variety of devices are available to support either or both ventricles with a great range of complexity and expense. This test discusses the use of ventricular assist devices and briefly describes the options available. The era is rapidly approaching when the use of implantable circulatory support devices will become commonplace and may outpace, and possibly outperform, the results currently obtained with cardiac transplantation.
