Single coronary artery from right aortic sinus in a very elderly patient

In the absence of other associated cardiac anomalies,single coronary artery (sca) per se is a rare anomaly detected during coronary angiography or autopsy. various types of sca detected during coronary angiography have already been described. we herein report a type of sca originating from the right sinus of valsalva,with the right circumflex,left circumflex,and left anterior descending coronary arteries arising from the proximal part of the sca in a 76-year-old female patient. she developed ventricular fibrillation during coronary angiography,which calls for caution while performing a coronary angiogram in such patients. © 2016 the authors
