Two unusual cases with coronary artery fistula were reported. The diagnoses were first made by color Doppler flow imaging and confirmed by selective coronary angiography and operation. In the first case, color Doppler revealed a continuous flow signal within the dilated left coronary artery and a turbulent jet within the right atrium. In the second case, color Doppler showed turbulent flow signals which could be traced from the proximal left coronary artery, along the left ventricular posterior wall and into the left ventricle. The high velocities at the site of drainage of fistula were recorded by the continuous-wave Doppler and the calculated pressure gradient confirmed that the abnormal flow was from the systemic circulation. We are of the opinion that color Doppler flow imaging is a reliable technique for detecting coronary artery fistula and the combination of color Doppler with continuous-wave Doppler is essential for evaluating the hemodynamics of the shunt flow.
报道了两例不寻常的冠状动脉瘘病例。诊断首先通过彩色多普勒血流成像做出，然后经选择性冠状动脉造影和手术证实。在第一例中，彩色多普勒显示扩张的左冠状动脉内有连续性血流信号，右心房内有湍流。在第二例中，彩色多普勒显示湍流信号，可从左冠状动脉近端沿左心室后壁追踪至左心室。通过连续波多普勒记录了瘘口引流部位的高速血流，计算出的压力梯度证实异常血流来自体循环。我们认为彩色多普勒血流成像是检测冠状动脉瘘的可靠技术，彩色多普勒与连续波多普勒相结合对于评估分流的血流动力学至关重要。
