We report a pediatric patient with nonatherosclerotic chronic total occlusion (CTO) of the left main coronary artery (LMCA) leading to complete LMCA atresia which was successfully recanalized via retrograde techniques through a previous internal mammary bypass graft. After the CTO was treated, the artery was found to be anomalous off the right cusp with an intramural coarse and slit-like orifice. The patient's ischemic symptoms resolved after Percutaneous Coronary Intervention (PCI), and she has continued to do well.
