ABSTRACT
Objective To investigate the incidence and clinical significance of coronary artery anomalies in adults undergoing coronary angiography. Methods Data of all patients underwent coronary angiography from Jan 2001 to Nov 2003 in our hospital were reviewed retrospectively. Results Among 2?824 adult patients, 61 had coronary artery anomalies of which 84.1% were anomalous origin and distribution. The total detection rate of coronary artery anomalies was 2.1%. Anomalies were found to be happened more in the right coronary artery than in the left coronary artery. Four cases failed to undergo selective right coronary angiography. Conclusion Coronary artery anomalies are not rare in adults. Some types of coronary artery anomalies can induce myocardium ischemia and require intervention. Catheterization diagnosis and therapy of patients with anomalous origin of coronary artery may be difficult2?
