ALVAD 1979: PRECEDENCE, POTENTIALS, PROSPECTS AND PROBLEMS.

A brief precis of the current status of this intracorporeal partial artificial heart or abdominal left ventricular assist device (ALVAD) can best be presented in the form of a summary of its clinical precedences, potentials, prospects and problems. In prior and concurrent publications, we have detailed some of this information. 1'2 We have not, however, focused on a retrospective, unifying or speculative view, i.e., what has been done, what could be done, or what should be done with this device or its modifications. A reasonable first approximation is shown in Figure 1.
