彩色多普勒超声心动图对冠状动脉瘘的诊断价值

Value of Color Doppler Echocardiography in Diagnosis of Coronary Artery Fistula

目的分析冠状动脉瘘的彩色多普勒超声心动图像特征,探讨其对冠状动脉瘘的诊断价值。方法对2000年1月—2012年10月收治的冠状动脉瘘11例的临床资料进行回顾性分析。结果彩色多普勒超声心动图显示冠状动脉显著扩张,走行迂曲,可见瘘管;可见左房、左室扩大,主动脉根部内径增宽;右冠状动脉右心室瘘多见;心腔内出现异常高速血流。应用彩色多普勒超声与冠状动脉造影测得的受累冠状动脉最宽内径及瘘口内径比较差异无统计学意义(P>0.05)。结论彩色多普勒超声心动图对冠状动脉瘘的诊断有很高的准确性及实用性价值,是一种安全无创的检查方法。

Objective To analyze characteristics and to explore the value of color doppler echocardiography in diagnosis of coronary artery fistula. Methods Clinical data of 11 patients with coronary artery fistula during January 2000 and October 2012 was retrospectively analyzed. Results Color Doppler echocardiography displayed significant extension, tortuous courser and visibility fistula in coronary artery; left atrium and ventricular enlargement, and broadening aortic root diameter were also found; the right ventricle of the right coronary artery fistulawas common; abnormal high speed blood flow existed in chambers heart. The differences of widest diameters and inner diameters in involved coronary artery by color doppler ultrasound, kinetocardiogram and coronary angiography were not statistically significant （P 〉 0.05）. Conclusion Color doppler echocardiography could provide exact and valuable information in diagnosis of coronary artery fistula, and it is a safe and noninvasive examination method.
