Abstract：Objective: To probe into the imaging characteristics of coronary artery fistula(CAF) in color Doppler echocardiography(CDE) and the value of CDE. Methods: Data of CDE in 11 patients with CAF were analyzed retrospectively to find out the characteristics and regularity of CAF. Results: Eleven cases were accurately diagnosed by CDE imaging. The CDE characteristics were obvious as follows:①Abnormal blood flow existed in the fistula heart chamber or pulmonary artery on CDE. ②The coronary artery with fistula was prominently enlarged. ③Most fistulas were at right coronary artery to right heart system. ④Continuous overfall both in systole and diastole were displayed in fistulas to right atrium, right ventricle, left atrium and pulmonary artery. Diastole overfall only existed in fistula to left ventricle. Conclusions: CDE has important value to clinic in detecting CAF.
