A 4-year-old boy admitted to our hospital due to congestive heart failure one year after the intracardiac repair of tetralogy of Fallot. Echocardiography and cineangiography revealed severe aortic regurgitation. The aortic valve replacement was performed with a prosthesis larger than the aortic annulus. Operative findings showed that the cause of aortic regurgitation was infective endocarditis. The aortic root was enlarged with pericardial patch and a 21 mm St. Jude Medical valve prosthesis was inserted in supraannular position. This technique was very useful for insertion of a prosthetic valve one or two sizes larger than the aortic annulus without risk of distorting the mitral valve or left ventricular function.
一名4岁男孩在法洛四联症心内修复术后一年因充血性心力衰竭入住我院。超声心动图和心血管造影显示严重主动脉瓣反流。采用比主动脉瓣环大的人工瓣膜进行主动脉瓣置换术。手术结果表明，主动脉瓣反流的原因是感染性心内膜炎。用心包补片扩大主动脉根部，并在瓣环上位置植入一枚21毫米圣犹达医疗公司的人工瓣膜。这项技术对于植入比主动脉瓣环大一号或两号的人工瓣膜非常有用，且不会有扭曲二尖瓣或影响左心室功能的风险。
