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.
德巴基-苏尔吉托尔主动脉瓣与常见的布覆盖式人工瓣膜不同，它有一个裸金属笼和一个热解碳球。该瓣膜植入了37例患者体内。有7例手术死亡（19%），均与瓣膜设计无关。30名幸存者已随访至5年，有12例晚期死亡。唯一的血栓栓塞事件导致了唯一一例与瓣膜相关的死亡。一名患者出现了人工瓣膜周围漏，另一名患者有溶血性贫血。小样本系列中血栓栓塞的发生率（3%）与布覆盖式瓣膜相当。在选择人工瓣膜时，这一点以及不存在与布磨损相关的并发症是重要的考虑因素。
