摘要
应用多普勒超声心动图技术比较三种正常功能的主动脉瓣膜的特点。在主动脉位置植入Carpentier-Edwards (n=29)、Hancock (n=25)和St. Jude (n=14)人工瓣膜的68例患者中，记录了最大主动脉流速(vmax)。卡彭迪埃-爱德华兹的平均V最大值为2.55±0.55 m/s，汉考克为2.49±0.74 m/s，圣裘德为2.74±0.31 m/s
Doppler echocardiographic evaluation of three models of prosthetic valves in the aortic position
Characteristics of three models of normally functioning prosthetic valves in the aortic position were compared using Doppler echocardiographic technique. Maximal aortic velocity (V max ) was recorded in 68 patients in whom Carpentier-Edwards (n=29), Hancock (n=25), and St. Jude (n=14) prosthetic valves had been implanted in the aortic position. Mean V max values were 2.55±0.55 m/s for Carpentier-Edwards, 2.49±0.74 m/s for Hancock and 2.74±0.31 m/s for St. Jude
