The following echocardiographic changes were found in 42 patients with catheterization data for tricuspid insufficiency: all echocardiographic dimensions of the right ventricle and right auricle are considerably increased; the interventricular septum reveals paradoxical movements in 38 per cent of the cases; the tricuspid echogram shows unspecific changes in the speed and amplitude parameters of the anterior tricuspid cusp--increased speed (D--E) and amplitude (C--E) of opening, increased speed of backward movement in an early diastole (E-F), increased speed of closing (A--C),increased duration of the final diastolic intervals A--C and Q--C, the difference between the Q--C interval duration of the tricuspidal valve and Q--C interval of the mitral echogram is pathologically increased, the ratio between the speed of E--F segment of the tricuspid valve and E--F segment of the mitral valve is also increased. The diagnostic sensitivity of those changes of the tricuspid echogram is about 75 per cent. EchoC-diagnosis of the tricuspid insufficiency is based on the combination of considerably increased EchoC-dimensions of the right ventricle and the right auricle, paradoxical movements of the interventricular septum and the changes of the speed and amplitude parameters of the tricuspid echogram.
在42例有三尖瓣关闭不全导管检查数据的患者中发现了以下超声心动图变化：右心室和右心房的所有超声心动图测量值均显著增加；38%的病例中室间隔出现矛盾运动；三尖瓣超声心动图显示三尖瓣前叶速度和幅度参数有非特异性变化——开放速度（D-E）和幅度（C-E）增加，舒张早期向后运动速度（E-F）增加，关闭速度（A-C）增加，舒张末期A-C和Q-C间期持续时间增加，三尖瓣Q-C间期与二尖瓣超声心动图Q-C间期的差值病理性增加，三尖瓣E-F段速度与二尖瓣E-F段速度之比也增加。三尖瓣超声心动图这些变化的诊断敏感性约为75%。三尖瓣关闭不全的超声心动图诊断基于右心室和右心房超声心动图测量值显著增加、室间隔矛盾运动以及三尖瓣超声心动图速度和幅度参数变化的综合判断。
