Key result
Coronary angiography reveals rare congenital absence of the right coronary artery compensated by the circumflex.
Why the study?
Single coronary artery is a rare congenital anomaly with variable presentations, where identifying and categorizing high-risk types can prevent adverse cardiac events and improve prognosis.

Answers are grounded in this paper and cite their sources.
Congenital absence of the right coronary artery is an exceedingly rare anomaly that can present with ischemic symptoms and be managed medically if no high-risk anatomical features are present.
Single coronary artery is a rare congenital anomaly in which a single coronary artery arises from the aortic root that supplies the entire heart. It has variable clinical presentations ranging from a completely benign course to sudden cardiac death. Identifying and categorizing to high-risk type based on clinical presentation and anatomical features can present adverse cardiac events and provides better prognosis.

Barakoti et al. (2024) conducted a case report in Congenital absence of right coronary artery (n=1). Coronary angiography was evaluated. Coronary angiography in a 51-year-old male with chest discomfort revealed a rare congenital absence of the right coronary artery, with the left circumflex artery supplying its territory.
