Key result
A newborn of a diabetic mother presented with severe septal myocardial hypertrophy and a circumflex artery occlusion leading to myocardial infarction.
Case Report (n=1)
Highlights an exceptional association between maternal diabetes and neonatal myocardial infarction due to circumflex artery occlusion.
Alerts clinicians to rare coronary occlusion in neonates of diabetic mothers with hypertrophy; single case leaves association hypothesis-generating.
We extracted L., the newborn of a diabetic mother, for antenatal diagnostic of myocardial hypertrophy and anomaly of foetal heart rate. Post-natal echocardiography showed severe septal myocardial hypertrophy with latero-basal myocardial akinesia. We did not observe a Doppler gradient through the left ventricular outflow. Selective coronary angiography showed an occlusion of the circumflex artery. Myocardial hypertrophy is a classic complication in newborns of diabetic mothers. The mother's diabetes and neonatal infarction remain an exceptional association. We discuss a different hypothesis to explain coronary occlusion and how myocardial infarction avoided septal obstruction.

Abbal et al. (2010) conducted a case report in Myocardial Infarction and myocardial hypertrophy (n=1). Maternal diabetes was evaluated. A newborn of a diabetic mother presented with severe septal myocardial hypertrophy and a circumflex artery occlusion leading to myocardial infarction.
