pubmed-article:8422494 | pubmed:abstractText | We reviewed clinical data in 216 patients who underwent isolated aortic valve replacement with the Medtronic Hall prosthesis. Between January 1983 and December 1990, a total of 216 prosthetic valves were implanted in 180 males and 36 females. Preoperatively, 45.5% of patients were in New York Heart Association (NYHA) Class III to IV. Cumulative follow-up was 682 years, and 3.2% of patients were lost to follow-up. The actuarial 5-year survival rate was 90% for the whole group. All the patients were anticoagulated with aceno-coumarol (Sintrom). There were no cases of structural dysfunction and one patient presented with valve thrombosis. The Medtronic Hall valve has a low rate of thromboembolic events without structural failure. It is an excellent device for aortic valve replacement. | lld:pubmed |
