A six-year-old girl with an atypical continuous precordial murmur, was suspected of having a coronary arteriovenous fistula. A markedly dilated right coronary artery was revealed by two-dimensional echocardiography. The pulsed Doppler examination showed a diastolic retrograde flow in the ascending aorta, with a normal flow in the left ventricular outflow tract. With the sample volume in the right ventricle a continuous turbulent flow was observed. Color flow mapping showed a turbulent, systolic-diastolic flow in the right ventricle. The fistula was confirmed by cardiac catheterization.
一名六岁女童有非典型的心前区连续性杂音，怀疑患有冠状动脉动静脉瘘。二维超声心动图显示右冠状动脉明显扩张。脉冲多普勒检查显示升主动脉有舒张期逆向血流，左心室流出道血流正常。将取样容积置于右心室时，观察到连续性湍流。彩色血流图显示右心室有收缩期和舒张期的湍流。通过心导管检查确诊了该瘘管。
