Doppler echocardiography has been applied in a study of the tricuspid and central venous blood velocity curves in a number of cases, including eleven cases of insufficiency, six cases of stenosis, five cases of steno-insufficiency of the tricuspid valve and one case of Ebstein's disease. The tracings were compared to normal reports and to those appartaining to a few patients with right ventricular failure from different causes. For six patients the venous blood velocity curve was recorded contemporaneously with the right atrioventricular pressure curves. Doppler echocardiography has proved that it can offer useful indications on tricuspid anomalies. The analysis of the central venous and tricuspid blood velocity curve allows us to detect hemodynamic alterations characteristic of this valvular disease.
多普勒超声心动图已应用于多项研究，涉及三尖瓣和中心静脉血流速度曲线，包括11例关闭不全、6例狭窄、5例三尖瓣狭窄合并关闭不全以及1例埃布斯坦畸形。将这些描记图与正常报告以及一些不同病因的右心室衰竭患者的描记图进行了比较。对6例患者同时记录了静脉血流速度曲线和右房室压力曲线。多普勒超声心动图已证明它能为三尖瓣异常提供有用的指征。对中心静脉和三尖瓣血流速度曲线的分析使我们能够检测出这种瓣膜疾病的特征性血流动力学改变。
