Key result
A newborn with a structurally normal heart suffered a massive perinatal myocardial infarction caused by thromboembolic occlusion of the left main coronary artery, likely occurring in utero.
Case Report (n=1)
Highlights the rare occurrence of perinatal myocardial infarction due to thromboembolic occlusion in a newborn with a structurally normal heart.
Alerts clinicians to consider in utero thromboembolism in perinatal MI with normal hearts; leaves open questions on incidence and prevention.
Myocardial infarction in a newborn infant in the absence of congenital heart disease and anomalous coronary artery anatomy is extremely rare. We report a case of a newborn with a structurally normal heart who presented shortly after birth with congestive heart failure and cardiovascular collapse suggestive of a hypoplastic left ventricle or critical aortic stenosis. This newborn had a massive myocardial infarction caused by thromboembolic occlusion of the left main coronary artery. Clinical, laboratory, and autopsy data suggest the event occurred in utero.

Muraskas et al. (1997) conducted a case report in Perinatal myocardial infarction (n=1). Thromboembolic occlusion of the left main coronary artery was evaluated on Massive myocardial infarction. A newborn with a structurally normal heart suffered a massive perinatal myocardial infarction caused by thromboembolic occlusion of the left main coronary artery, likely occurring in utero.
