Aortopulmonary fistula occurring as a result of a rupture of the aortic wall of a stentless valve has not been previously reported. A 71-year-old woman suffered aortopulmonary fistula 15 months after replacement of the aortic root with a Freestyle stentless valve (Medtronic, Inc, Minneapolis, MN) and Dacron graft extension to replace the aortic valve and the ascending aorta to the aortic arch. We describe the successful repair of the fistula and simultaneous mitral valve replacement. The cause of deterioration of the aortic wall of the stentless valve, which gradually developed and ruptured, may have been primarily structural injury at the previous operation, with additional insult from the surgical adhesive used.
无支架瓣膜主动脉壁破裂导致主肺动脉瘘此前未见报道。一名71岁女性在使用Freestyle无支架瓣膜（美敦力公司，明尼阿波利斯，明尼苏达州）置换主动脉根部并使用涤纶移植物延伸以置换主动脉瓣及升主动脉至主动脉弓15个月后发生了主肺动脉瘘。我们描述了瘘管的成功修复及同期二尖瓣置换术。无支架瓣膜主动脉壁逐渐发展并破裂的原因可能主要是先前手术造成的结构损伤，以及手术粘合剂带来的额外损害。
