Percutaneous coronary intervention in a 3-year-old with hypoplastic left heart syndrome.

Mortality outcomes associated with surgical palliation for hypoplastic left heart syndrome (HLHS) have continued to improve with time. Despite these advances, interstage mortality continues to be difficult to predict and prevent. This case report details a 3-year-old boy with HLHS palliated with a Glenn shunt who presented with acute myocardial infarction due to near total occlusion of the distal right coronary artery. He was treated by thrombus aspiration with good clinical response. This is the first report of thrombus aspiration in complex pediatric congenital heart disease and demonstrates the utility of collaboration between congenital and adult cardiologists.
