title: Absence of left anterior descending coronary artery associated with anomalous origin of left circumflex coronary artery from the right coronary artery: a case report and review.
abstract: In this report we present a case of a 30-year-old female patient with a single coronary artery, which consisted of a right coronary artery from which there was an anomalous origin of the left circumflex coronary artery. There was no left anterior descending coronary artery. The clinical and other noninvasive diagnostic features of this rare angiographic variant are described and compared to other known varieties of coronary anomalies. The absence of objective evidence of ischemia or left ventricular functional impairment and analysis of the angiographic data suggest that this is another benign variant of coronary anatomy.
