A new method has been devised to assess the competence of the canine aortic valves, before implantation. This method would provide a better selection of aortic valves before their insertion and may reduce the incidence of postoperative incompetency. Comparison of canine pulmonary and aortic valve function, at various pressures, revealed that the pulmonary valves were regurgitant at higher pressures, in comparison to aortic valves. Formalin preserved valves were found to be significantly regurgitant.
已经设计出一种新方法，用于在植入前评估犬主动脉瓣的功能。该方法将在主动脉瓣植入前提供更好的选择，并可能降低术后功能不全的发生率。在不同压力下对犬肺动脉瓣和主动脉瓣功能进行比较，结果显示，与主动脉瓣相比，肺动脉瓣在较高压力下会出现反流。研究发现，福尔马林保存的瓣膜有明显的反流现象。
