The long term performance characteristics of the 2400 and 1260 series of Starr-Edwards aortic prostheses were investigated by a follow up study of clinical outcome of 327 patients discharged from hospital with isolated aortic valve replacement. Follow up lasted for up to 10 years and was based on 1616 patient-years. The 2400 series cloth covered tracked valve was implanted in 182 patients from 1974 to 1980 and the 1260 series bare strut silastic ball valve was inserted in 145 patients from 1979 to 1983. Total 10 year mortality and valve related morbidity were low and no cases of mechanical valve failure were recorded. There were no significant actuarial differences in mortality or valve related morbidity between the 2400 and 1260 valves. Starr-Edwards models 2400 and 1260 aortic valve prostheses showed excellent durability without any mechanical failures over a 10 year period. The long term outcome of isolated aortic valve replacement with these models is associated with a low frequency of valve related complications.
通过对327例因单纯主动脉瓣置换术出院患者的临床结局进行随访研究，调查了斯塔尔-爱德华兹2400系列和1260系列主动脉瓣膜假体的长期性能特征。随访持续了长达10年，基于1616患者年。1974年至1980年，182例患者植入了2400系列布覆盖跟踪瓣膜，1979年至1983年，145例患者植入了1260系列裸支柱硅橡胶球阀。10年总死亡率和瓣膜相关发病率较低，未记录到机械瓣膜故障病例。2400和1260瓣膜在死亡率或瓣膜相关发病率方面没有显著的精算差异。斯塔尔-爱德华兹2400型和1260型主动脉瓣膜假体在10年期间表现出出色的耐用性，没有任何机械故障。使用这些型号进行单纯主动脉瓣置换术的长期结局与瓣膜相关并发症的低发生率相关。
