Anomalous origin of the right coronary artery from the left sinus of valsalva

The clinical significance of anomalous origin of the right coronary artery (RCA) has been controversial. Roberts et al¹ reported a compilation of necropsy data from 4 studies. Of 26 patients reported, none had symptoms of cardiac dysfunction or death that could be attributed to an anomalous origin of the RCA. Roberts et al reviewed angiographie data from 6 studies involving living patients in whom anomalous origin of the RCA was identified. Among 31 patients, 9 (29%) had symptoms of cardiac dysfunction unassociated with significant coronary or noncoronary cardiac disease. We report our experience with 12 patients who had angiographic evidence of anomalous origin of the RCA.
