A case never described in adults before is here reported. A 35-year-old patient who had referred precordial pain in effort for seventeen years was investigated after having been submitted to correction of coarctation of the aorta, and had the following diagnosis: anomalous origin of the circunflex artery. In the intraoperatory, the latter was found to proceeed from the right pulmonary artery. The anomalous ostio was sutured and a free graft was made, from the right internal thoracic artery to the circunflex coronary. In addition to the unusualness of such pathology, some physiopatologic considerations related to the coarctation of the aorta may be made, in this particular case.
