摘要
目的:探讨各类型冠状动脉瘘(CAF)的彩色多普勒超声心动图(CDE)图像特征及超声心动图诊断CAF的价值。方法:对11例CAF患儿进行回顾性分析,寻找CAF图像特征及规律性。结果:根据CDE图像特征对11例患儿作出正确诊断。CAF的CDE具有明显的图像特征:①在瘘入的心腔或肺动脉内彩色多普勒血流显像(CDFI)显示异常血流束信号;②瘘的冠状动脉明显扩张;③右冠状动脉瘘多见,瘘入右心系统者最常见;④瘘入右房、右室、左房、肺动脉时均为双期连续湍流频谱,瘘入左室时为舒张期湍流频谱。结论:CDE对CAF的诊断有很高的价值。
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 fight 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.
