A patient with a double-chambered right ventricle and cor triatriatum dexter was presented. The non-invasive diagnosis of cor triatriatum dexter was stressed. A plate-like echo was imaged in the right atrium using two-dimensional echocardiography. It divided the atrium into two chambers. Contrast echocardiography revealed delayed filling of the lower portion of the atrium. Pulsed Doppler echocardiography demonstrated systolic turbulence in the lower portion of the atrium, indicating that the plate-like structure produced a stenosis in the right atrium. We conclude that non-invasive methods including contrast echocardiography and pulsed Doppler echocardiography, are effective in identifying stenoses in the right atrium.
本文报告了一例双腔右心室合并右房三房心患者。着重介绍了右房三房心的无创诊断。二维超声心动图显示右心房内有一板状回声，将心房分为两个腔室。对比超声心动图显示心房下部充盈延迟。脉冲多普勒超声心动图显示心房下部有收缩期湍流，提示板状结构导致右心房狭窄。我们得出结论，包括对比超声心动图和脉冲多普勒超声心动图在内的无创方法，对于识别右心房狭窄是有效的。
