In a two-year period 105 patients underwent isolated aortic valve replacement without hospital death. Eighty-three patients were operated on using hypothermic ischemic arrest; 22 patients had coronary perfusion. The early postoperative cardiac performance and incidence of complications did not differ between groups, although cardiopulmonary bypass time was shorter in the ischemic arrest group. These data suggest that ischemic arrest is a satisfactory method for myocardial preservation. However, because of the low hospital mortality rate with either method, these results and those of others cannot be taken to indicate the superiority of any method of myocardial preservation.
在两年时间里，105例患者接受了单纯主动脉瓣置换术，无一例医院死亡。83例患者采用低温缺血停搏进行手术；22例患者进行了冠状动脉灌注。尽管缺血停搏组的体外循环时间较短，但两组术后早期心脏功能和并发症发生率并无差异。这些数据表明，缺血停搏是一种令人满意的心肌保护方法。然而，由于两种方法的医院死亡率都很低，这些结果以及其他研究结果并不能表明任何一种心肌保护方法具有优越性。
