A 50-year-old woman who had been undergoing hemodialysis for 18 years underwent mitral valve replacement because of mitral valve stenosis. Her mitral valve leaflet and annulus were highly calcified, and it was impossible to remove the posterior leaflet from the ventricular wall. At the time of surgery, noneverted horizontal mattress sutures were placed from the left ventricle to the left atrium on the anterior half of the mitral annulus and everted horizontal mattress sutures on the left atrial wall close to the calcified posterior annulus. A 25-mm St. Jude valve was seated successfully at a supra-annular position. The St. Jude valve is suitable for this technique because its leaflets protrude less into the left ventricle.
一名接受了18年血液透析的50岁女性因二尖瓣狭窄接受了二尖瓣置换术。她的二尖瓣叶和瓣环高度钙化，无法将后叶从心室壁上移除。手术时，在二尖瓣环前半部分从左心室到左心房放置了非外翻水平褥式缝线，在靠近钙化后瓣环的左心房壁上放置了外翻水平褥式缝线。一个25毫米的圣犹达瓣膜成功地置于瓣环上位置。圣犹达瓣膜适用于这种技术，因为其瓣叶较少突入左心室。
