RESUMEN
<p><b>OBJECTIVE</b>To investigate the value of dual-source computed tomography (DSCT) angiography in the examination of congenital coronary artery anomalies.</p><p><b>METHODS</b>We retrospectively examined 2530 patients by DSCT angiography between January 2008 and September 2010. Congenital coronary artery anomalies were shown by maximum intensity projection, curved planar reconstruction, and volume rendering.</p><p><b>RESULTS</b>A total of 284 segments with congenital coronary artery anomalies in 225 patients were displayed. The anomalies included those originated from the main branch of coronary artery (n=121, including 35 segments of right coronary artery with high take-off origin and 24 segments of left coronary artery, 17 segments of right coronary artery dated from left aortic sinus, 4 segments of left coronary artery dated from right aortic sinus, 2 segments of left coronary artery dated from posterior aortic sinus, 2 segments of single coronary artery, and 37 segments of para-coronary artery) , coronary artery dysplasia (n=18) , coronary artery fistula (n=9, including 4 segments of right coronary artery-right ventricle fistula, 2 segments of right coronary artery-pulmonary artery fistula, 2 segments of left coronary artery-left ventricle fistula, and 1 segments of left coronary artery-pulmonary artery fistula) , and myocardial bridge (n=136) . In addition, 818 segments of left sinuatrial nodal artery original anomalies in 1720 patients whose sinuatrial nodal artery were well shown.</p><p><b>CONCLUSION</b>DSCT can be helpful in detecting the anomalies of coronary artery.</p>
