[Cor triatriatum dexter: a case report with particular reference to the echocardiographic features].
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.
