• In this experimental study, optimal driving mode during bi-ventricular assistance was evaluated in swine. After bi-ventricular failure was made, right and left ventricular assist device (sac type, stroke volume; 40ml) were applied.Group I animals were treated with BVAD, in the condition pump flow ratio R:L=1:≤0.5, group II R:L=1:0.5<≤1, and group III were supported, pump flow ratio R:L=1:1<.Left ventricular failure, high left atrial pressure, left ventricular diastolic pressure, low aortic pressure, and low cardiac output was recognized in group I. But group III was kept almost satisfactory hemodinamic condition, without left ventricular failuar. And during group III support, left atrial pressure/central venous pressure was indicated about 2.
