title: Successful transradial intervention for two lesions with dual anomalous origins of coronary arteries.
abstract: A 76-year-old male was admitted to our hospital for effort angina pectoris. His coronary computed tomography and coronary angiography revealed anomalous origins of the left anterior descending artery (LAD) from the proximal right coronary artery (RCA) and the left circumflex coronary artery (LCX) from the separate ostium in the right coronary cusp. Severe stenoses were present in the proximal segment of the LAD and in the middle segment of the LCX, which were successfully treated by 5 French (Fr) transradial approach intervention. Congenital coronary anomalies are relatively rare, with a prevalence of approximately 1.3% in a large-series study undergoing coronary angiography. Such anomalies occur in several anatomical arrangements, which have been classified in a number of research reports. Here we describe previously unreported dual anomalous origins of coronary arteries associated with significant atherosclerotic lesions, which were successfully treated by 5 Fr transradial approach intervention.
