How and when to treat patients with coronary occlusion after arterial switch surgery is still under debate. We report the case of a child who underwent arterial switch surgery a few weeks after birth. At the age of 8 years, coronary angiography showed a total occlusion of the left main coronary artery, successfully treated using percutaneous coronary intervention. Percutaneous coronary recanalization of chronic total occlusions might be considered the first treatment strategy in children who undergo complex surgical procedures.
