Abstract

Neonatal myocardial infarction is a rare clinical entity that is associated with high mortality. Reported treatment strategies include supportive care, extracorporeal membrane oxygenation, thrombolytics, and surgical thrombectomy. Herein we report a neonate who developed an acute myocardial infarction owing to a thrombus in the proximal left coronary artery. At 24 hours of life, he was treated with local (intracoronary) thrombolytic therapy at a lower dose than previously reported, as well as with systemic anticoagulation. There was subsequent angiographic resolution of the thrombus and normalisation of left ventricular function.
