An asymptomatic 52-year-old woman was referred for the evaluation of a 4/6 continuous murmur in the right parasternal border. Patient had no relevant family history of congenital heart disease. The electrocardiogram showed sinus rhythm and the echocardiogram revealed a round, vascular communication from the left aortic sinus (LAS) to the right atrium (RA), with continuous turbulent flow on Doppler evaluation. Additionally, a cardiac computed tomography angiography was performed for better delineation of coronary and extra-cardiac anatomy. 3D volume rendered reconstructions showed a large and tortuous ‘tunnel-like’ structure arising from the LAS, coursing posteriorly to the aortic root and terminating in the roof of the RA, just inferior and...

主动脉右心房隧道：意外诊断。

一名无症状的52岁女性被转诊至胸骨旁右边界连续发生4/6杂音。患者没有相关的先天性心脏病家族史。心电图显示窦性心律，超声心动图显示从左主动脉窦（LAS）到右心房（RA）的圆形血管连通，多普勒评估显示持续的湍流。另外，进行了心脏计算机断层造影血管造影以更好地描绘冠状动脉和心脏外解剖结构。3D体绘制的重建图像显示，LAS产生了一个大而曲折的“隧道状”结构，向主动脉根部后方偏移，并终止于RA的房顶，仅次于并...
