title: Experience with the DeBakey-surgitool aortic prosthetic valve.
abstract: The DeBakey-Surgitool aortic valve differs from popular cloth-covered prostheses by having a bare metal cage and a pyrolytic carbon ball. This valve was implanted in 37 patients. There were 7 operative deaths (19%), none of which was related to the valve design. Thirty survivors have been followed up to five years with 12 late deaths. The single thromboembolic event resulted in the only valve-related death. One patient developed a periprosthetic leak and another has hemolytic anemia. The incidence of thromboembolism in small series (3%) is comparable to that with the cloth-covered valves. This and the absence of complications related to cloth wear are important considerations when selecting a prosthesis.
