Introduction
Anomalous origin of the circumflex (Cx) coronary artery from the right sinus of Valsalva is the most common coronary anomaly and is usually considered “benign.” Due to the acute nature of the origin of this vessel, some have proposed that there is an increase in the degree of CAD present in these vessels. We noted a large number of these anomalous vessels in our patients and sought to better characterize this unique cohort.
Methods
We performed a retrospective cohort study of all patients ( n =18) with anomalous Cx from the right coronary cusp who had undergone cardiac catheterization at our VA Medical Center. Patients were identified by review of all cardiac catheterizations performed at our center from 2006 to 2010. Comprehensive chart analysis and quantitative coronary angiography (QCA) were performed by two independent operators for all cases.
