title: A very rare case of single coronary artery anomaly, with left anterior descending and left circumflex arteries originating separately from proximal right coronary artery.
abstract: Coronary artery anomalies are rare, with the reported prevalence of 0.2% to 1% in routine angiographic studies. Among them, presence of a single coronary artery is one of the rarest anomalies, comprising less than 3% of all coronary anomalies. In this article we report a case of single coronary artery anomaly with left anterior descending and left circumflex arteries arising separately from proximal right coronary artery, and left anterior descending artery reaching atrioventricular sulcus by passing between aortic and pulmonary artery trunci. The patient underwent off-pump coronary artery bypass grafting and is currently symptom-free.
