Abstract
The ideal substitute for the diseased aortic valve is yet to be found. We documented the effects of the Freestyle stentless valve (Medtronic Inc. Minneapolis Minn.) on clinical outcome and left ventricular mechanics. The valve was implanted in 21 patients, age ranging from 62 - 88 years (mean 71 ± 3.2) 16 were male and 5 female. In 14 patients the modified subcoronary technique was used for valve implantation and the other 7 patients received a total root replacement. The mean ischemic time was 90 ± 13 minutes. There were no in-hospital deaths or major complications. Mean stay in the intensive care was 1.3 days and mean hospital stay was 7±2 days. At discharge, 2 patients had trivial aortic insufficiency, and all other patients had perfectly functioning aortic valves. Follow-up period ranged between 4-18 months (mean 11 months). During this period, hemodynamic function improved, gradients dropped slightly (p=ns), and there were no valve-related complications. During the follow-up period, trivial aortic insuffiency seen in two patients at discharge, remained the same. Corsequently, we advocate the use of this tyse of valve in patients requiring biological valves.
