The actuarial survival and thromboembolic rates for the three types of cloth-covered Starr-Edwards mitral prostheses, models 6300, 6310/6320, and 6400 followed 6, 5, and 2 years, respectively, were not significantly different throughout the years they were followed. The combined cumulative survival and thromboembolic proportion at 5 years for these prostheses were 71 and 66 per cent, respectively. The thromboembolic rates were not different in the following two groups: (a) 238 patients receiving anticoagulants, and (b) 52 patients who had discontinued or who were not receiving anticoagulants. Four patients thrombosed their mitral prostheses. Another 8 per cent had class 3 symptoms after operation, which were attributed to myopathic or restrictive left ventricular dysfunction or other valvular disease.
三种布覆盖的斯塔尔-爱德华兹二尖瓣假体，型号6300、6310/6320和6400，分别随访了6年、5年和2年，其精算生存率和血栓栓塞率在整个随访期间无显著差异。这些假体在5年时的累积生存和血栓栓塞合并比例分别为71%和66%。以下两组的血栓栓塞率无差异：（a）238例接受抗凝治疗的患者，以及（b）52例已停用或未接受抗凝治疗的患者。有4例患者二尖瓣假体形成血栓。另有8%的患者术后出现3级症状，这归因于肌病性或限制性左心室功能障碍或其他瓣膜疾病。
