Two-dimensional (2-D) and Doppler echocardiographic features of three cases of coronary arteriovenous fistula (CAVF) were analyzed. The final diagnosis was confirmed by coronary angiography in each case. In cases 1 and 2, the CAVF arose from the right coronary artery and drained into the right atrium and right ventricle, respectively. The origin and draining site of the CAVF could be visualized by 2-D echocardiograms. The Doppler studies revealed a unidirectional flow within the lumen of the CAVF. In case 3, with a small CAVF originating from both the right coronary artery and left circumflex artery draining into the main pulmonary artery, no abnormal vascular structure could be detected by the 2-D echocardiogram; with Doppler study, a diastolic as well as systolic flow signal directed toward the distal pulmonary artery could be detected.
分析了3例冠状动脉瘘（CAVF）的二维（2-D）和多普勒超声心动图特征。每例均经冠状动脉造影确诊。病例1和病例2中，冠状动脉瘘分别起源于右冠状动脉，引流至右心房和右心室。二维超声心动图可显示冠状动脉瘘的起源和引流部位。多普勒研究显示冠状动脉瘘管腔内为单向血流。病例3中，一个小冠状动脉瘘起源于右冠状动脉和左旋支动脉，引流至主肺动脉，二维超声心动图未检测到异常血管结构；多普勒研究显示，可检测到朝向远端肺动脉的舒张期和收缩期血流信号。
