A 35-year old female patient underwent a double valve replacement. The operative findings revealed a small aortic annulus (about 17 mm in diameter). In order to implant the adequate-size prosthetic valve, the aortic and mitral annulus were enlarged using the technique described by Rastan and Manouguian. The annulus were enlarged with a patch of gel-sealed dacron graft. After the enlargement, the prosthetic valve No. 23A and 31M could be implanted in the aortic and mitral annulus, respectively. This is an effective technique to enlarge the aortic and mitral annulus in a double valve replacement procedure. The annular diameter could be increased approximately 30 per cent.
一名35岁女性患者接受了双瓣膜置换术。手术发现显示主动脉瓣环较小（直径约17毫米）。为了植入尺寸合适的人工瓣膜，采用Rastan和Manouguian描述的技术扩大了主动脉瓣环和二尖瓣环。用一片凝胶密封的涤纶补片扩大瓣环。扩大后，分别将23A号和31M号人工瓣膜植入主动脉瓣环和二尖瓣环。这是在双瓣膜置换手术中扩大主动脉瓣环和二尖瓣环的有效技术。瓣环直径可增加约30%。
