Abstract:
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.

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
