The case of a patient with right coronary artery-right atrial fistula was reported, with special reference to the noninvasive evaluation. On two-dimensional echocardiography in the short axis view, it was observed that the fistula had an entrance from the right coronary cusp, with the body of fistula sigmoid-like appearance running along the tricuspid ring and atrioventricular groove. In the subxyphoidal approach the exit of fistula into the right atrium was demonstrated. Intrafistular blood flow and drainage flow into the right atrium were identified by color flow mapping. The potential usefulness of the combination of two-dimensional, pulsed Doppler echocardiography and color flow mapping were discussed.
报道了一例右冠状动脉-右心房瘘患者的病例，特别提及无创评估。在短轴视图的二维超声心动图上，观察到瘘管从右冠状动脉瓣叶处进入，瘘管主体呈乙状结肠样外观，沿三尖瓣环和房室沟走行。在剑突下途径中，显示了瘘管进入右心房的出口。通过彩色血流图确定了瘘管内的血流以及流入右心房的引流血流。讨论了二维、脉冲多普勒超声心动图和彩色血流图联合应用的潜在价值。
