After a patient has been supported with a circulatory assist device, the
expected outcomes are weaning, bridging, or discontinuation of support. An
early insertion of the device will avoid deterioration of the heart and
other organs to an irreversible condition. Cardiac assistance for a minimum
of 24 hours is recommended with a mild dose of anticoagulant. It is
necessary to monitor the hemodynamic functions during circulatory support
and weaning. Most of the mechanical devices are quite reliable, and
complications during ventricular assist are easily managed. The patient
should be in the same condition as in ordinary elective transplant
candidate before transplantation. Patients with an artificial heart or
ventricular assist device should not be on the priority emergency list for
cardiac transplantation. Patients suffering from cardiogenic shock can be
stabilized with a ventricular assist device to allow the heart to recover
or be provided with other treatment. A circulatory support device can also
be used as a bridge for patients awaiting a cardiac transplant.
