We report four long-term survivors after valve replacement with a Starr-Edwards (S-E) mitral caged-disk valve. A model 6520 disk valve, size 3M, had been used in all of the four patients. Of the four patients, three underwent replacement of the disk valves 23, 24, and 26 years after mitral valve replacement (MVR), respectively. A pacemaker was implanted in the remaining patient 33 years after MVR. The S-E disk valves were considered hemodynamically slightly stenotic compared with modern bileaflet valves. No disk wear was detected in any of the three explanted valves, and in the remaining patient, a noninvasive evaluation of the disk showed that it was functioning normally. These results suggest the favorable long-term durability of the S-E disk valve.
我们报告了4例使用斯塔尔-爱德华兹（S-E）二尖瓣笼球瓣进行瓣膜置换后的长期存活者。4例患者均使用的是型号为6520的3M尺寸球瓣。4例患者中，3例分别在二尖瓣置换（MVR）术后23年、24年和26年进行了球瓣置换。其余1例患者在MVR术后33年植入了起搏器。与现代双叶瓣相比，S-E球瓣的血流动力学表现为轻度狭窄。在3个取出的瓣膜中均未检测到瓣膜磨损，对于其余患者，对球瓣的无创评估显示其功能正常。这些结果表明S-E球瓣具有良好的长期耐用性。
