A 65-year-old woman was admitted to the hospital because of anterior chest pain. Computed tomography and transthoracic 2-D echocardiogram demonstrated aortic valvular stenosis with calcification of whole aortic root. Cardiac catheterization study showed a transaortic pressure gradient of 73 mmHg and coronary angiography showed 75% stenosis at the right coronary ostia. Aortic valve replacement and coronary artery bypass grafting were planned. At operation, sinotubular junction and bilateral coronary ostia severely calcified with stenosis, prompted us to translocate the aortic valve with the composite graft, a 19 mm Bicarbon prosthesis and 25 mm woven Dacron graft. The postoperative course was uneventful. On cardiac catheterization done 27 days after operation, satisfactory valve motion and patent coronary bypass grafts were confirmed.
一名65岁女性因前胸痛入院。计算机断层扫描和经胸二维超声心动图显示主动脉瓣狭窄伴整个主动脉根部钙化。心导管检查显示跨主动脉压力梯度为73 mmHg，冠状动脉造影显示右冠状动脉开口处狭窄75%。计划进行主动脉瓣置换和冠状动脉搭桥术。手术中，窦管交界处和双侧冠状动脉开口严重钙化并伴有狭窄，促使我们用复合移植物（一个19毫米的生物碳假体和一个25毫米的编织涤纶移植物）进行主动脉瓣移位。术后过程顺利。术后27天进行的心导管检查证实瓣膜运动良好且冠状动脉搭桥移植物通畅。
