Abstract Objective: To research the CT findings of congenital variation and malformation of coronary artery. Methods: There were 1 402 patients who had underwent prospective ECG-triggering coronary CTA in our hospital were enrolled this study. We reconstructed the raw data by several post-processing techniques and summarized the CT findings of congenital variation and malformation of coronary artery. Results: We found 364 cases of variation and malformation of coronary artery in this study, including one case of absence of left main coronary artery, 3 cases of short left main coronary artery and one of them has accessary coronary artery, 3 cases of accessary coronary artery or third coronary artery, 7 cases of right coronary originated from the left coronary sinus, one case of single coronary artery, one case of abnormal coronary artery anastomosis, one case of the right posterior descending coronary artery aneurysm with left atrial diverticulum, three cases of coronary artery aneurysm, 20 cases of coronary artery tortuosity, 325 cases of myocardial bridge-mural coronary artery. Conclusion: Prospective ECG-triggering coronary CTA can significantly reduce the radiation dose of coronary CTA and can accurately and clearly show the variation and malformation of coronary artery.
