Abstract :
Congenital absence of the left circumflex artery is a rare coronary anomaly with few reported cases in the literature. These patients
are usually diagnosed incidentally when they undergo coronary angiography or coronary CT to rule out underlying coronary artery
disease. In this article, we report a case of a 46-year-old man who was incidentally found to have a congenitally absent left circumflex
artery with a superdominant right coronary artery after a workup was initiated for frequent premature ventricular contractions
and regional wall motion on echocardiogram. A review of the clinical presentation, symptoms, and diagnostic modalities used to
diagnose this entity is presented.
