In a series of 130 patients undergoing aortic valve replacement, 20 had the ascending aorta enlarged with a Dacron patch. Eight of these required division of the annulus with extension of the incision inferiorly to the anterior leaflet of the mitral valve. The resulting separation of the annulus allowed a larger size valve to be inserted. Glutaraldehyde-fixed procine heterografts were used in all patients having the annulus enlarged. No deaths occurred in those patients having annular enlargement, and the post-operative studies show no evidence of mitral valve dysfunction.
在130例接受主动脉瓣置换术的患者中，20例升主动脉用涤纶补片进行了扩大。其中8例需要切开瓣环，并将切口向下延伸至二尖瓣前叶。由此产生的瓣环分离使得能够插入更大尺寸的瓣膜。所有瓣环扩大的患者均使用了戊二醛固定的猪异种移植物。瓣环扩大的患者中无死亡病例，术后研究未显示二尖瓣功能障碍的证据。
