The St. Jude Medical cardiac valve is a low-profile, bileaflet, central-flow prosthesis made entirely of pyrolytic carbon. A total of 261 St. Jude valves were implanted in 253 patients during a 25-month period. Perioperative mortality for the entire series was 9.1%, including patients undergoing reoperation for valve disease and those having associated cardiac procedures. There were four nonfatal thromboembolic episodes during the follow-up period, resulting in a risk of thromboembolism for aortic and mitral valves of 2.1% and 2.1% per patient year, respectively. There were no instances of structural failure of the valve, and no valve-related hemolysis occurred. Two-year actuarial survival was 95%. Hemodynamic studies indicate that the valve has the lowest transvalvular pressure gradient of any prosthetic mechanical valve available, and we bel...
