title: Anomalous Origin of the Right Coronary Artery from the Midportion of the Left Anterior Descending Artery: A Rare Coronary Anomaly.
abstract: The anomalous origin of the right coronary artery (RCA) as a branch from the left anterior descending artery (LAD) is a very rare variation of the single coronary artery anomaly. The anomalous vessel arises from the proximal or midportion of the LAD and courses anterior to the pulmonary artery trunk in most instances. In this case report, a 61-year-old woman is introduced who underwent coronary angiography following inferoposterior myocardial infarction, in which an anomalous RCA was seen originating from the midportion of the LAD. There was also a separate small artery originating from the right coronary sinus, which was most probably a right atrial branch.
