ABSTRACT

Conventional heart-lung-machines (HLM) used for many cardiosurgical procedures lead to an impaired function of nearly all organs. This deleterious effect may be reduced by miniaturized HLMs. Therefore we report on our first experiences in 9 patients (4 women, 5 men) undergoing beating heart coronary artery bypass grafting from 10/01 to 04/02 in our department employing a miniaturized HLM with the Deltastream extracorporeal rotary blood pump. Eight patients had an uneventful postoperative course, one patient died on the first postoperative day. Using this miniaturized HLM beating heart coronary artery bypass grafting was successful in all patients. Further studies are necessary to support these results.
