Abstract

To know the optimal duration of cardiopulmonary bypass (CAB) assist, we evaluated the time course of functional ventricular recovery from ischemia in 18 open chest dogs. Emax, which is a load-independent index of contractility, was used. We concluded that after severe intraoperative myocardial ischemia, CPB assist was beneficial up to 60min for the recovery of cardiac function. Prolonged CAB assist (more than 60min) would not further improve cardiac function.
