RESUMO
We describe the rare angiographic finding of the right coronary artery arising from the middle portion of the left anterior descending coronary artery in a patient with atherosclerotic coronary artery disease and acute myocardial infarction. This anatomic variation has been previously described only four times in the modern literature.
Relatamos raro achado angiográfico da artéria coronária direita saindo do terço médio da artéria coronária descendente anterior em paciente com doença aterosclerótica coronariana e infarto agudo do miocárdio. Apenas 4 casos desta variação anatômica foram encontrados na literatura

A 43 year-old female patient with angina pectoris and vasospasm demonstrated in the anomalous left circumflex (Cx) and right coronary (RCD) arteries by coronary angiograph. Origin of the left Cx from the RCD is the most common coronary anomaly and generally, is considered to be benign. Nevertheless, myocardial ischemia in patient with this anomaly has been described. To our knowledge, this is the first reported case of coronary vasospasm occurring simultaneously in the anomalous left Cx and RCD arteries. The diagnostic troubles and the potential danger of this association were emphasized.
