Abstract:
An anomalous origin of the right coronary artery (RCA) from the left anterior descending artery (LAD), also known as a single coronary artery, is an extremely rare finding in clinical practice. It is usually a benign anomaly; however, symptoms are highly dependent on the course that the anomalous RCA takes after branching off of the LAD. We present a case of a patient who had decompensated heart failure and was detected to have a single coronary artery. The patient was treated with guideline-directed medical therapy with notable improvement in clinical status in the following days. Enhanced awareness of congenital cardiac anomalies may help guide management.

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

Diastole: The Relaxation Phase
During diastole, all four heart chambers relax. The atrioventricular (AV) valves open, and the semilunar valves close. This phase sees the lowest chamber pressures, promoting ventricular filling. Venous blood enters the heart through the...
