A 32-year-old woman developed heart failure. She had received Glenn operation 26 years ago and Fontan operation using valved conduit (Björk-Shiley: 21 mm) seven years ago for tricuspid atresia type 1b. She underwent extirpation of the struck prosthetic valve. Neither graft stenosis nor pressure gradient between the right atrium and the pulmonary artery were observed on postoperative right arteriography. Sternotomy on redo Fontan operation should be carefully performed for preventing breaking down the implanted valved conduit. Though the prosthetic valve was not necessary on redo Fontan operation, anticoagulation after operation should be done.
一名32岁女性出现心力衰竭。她26年前接受了格林手术，7年前因1b型三尖瓣闭锁接受了使用带瓣管道（Björk-Shiley：21mm）的Fontan手术。她接受了故障人工瓣膜摘除术。术后右心造影未观察到移植血管狭窄或右心房与肺动脉之间的压力梯度。再次进行Fontan手术时，应谨慎进行胸骨切开术，以防止植入的带瓣管道破裂。尽管再次进行Fontan手术时人工瓣膜并非必需，但术后仍应进行抗凝治疗。
