Abstract
Sixteen patients received circulatory support using centrifugal pump for the purpose of either left ventricular assist(6 cases), or veno-arterial bypass ( VAB, 10 cases). Out of six LV-assisted patients, two could be weaned but only one was the long survivor. Out of ten VAB assisted patients, four could be weaned and two were the long survivors. Percutaneous approach of VAB had the advantage to minimise bleeding from the cannulation sites. Although, circulatory assist using the centrifugal pump has some disadvantages in durability and antithrombogenesity, it seems to be useful for circulatory assist in patients with right ventricular failure who requires a relatively short term mechanical support.
