We report the case of a 35-year-old male patient with congenital atresia of the left main coronary artery, a rare disease with few cases reported in the literature. In this anomaly, the left coronary ostium is absent, the proximal left main trunk ends blindly and blood flow is retrograde from the right to the left coronary artery by small collateral arteries. Differential diagnosis includes other congenital malformations (single right coronary artery and anomalous origin of the left coronary artery from the pulmonary artery) and acquired atherosclerotic disease of the left main coronary artery.
