Negative delayed‐enhancement magnetic resonance imaging of the heart suggests a diagnosis of neonatal transient myocardial ischaemia

We report a term neonate presenting after birth with shock and cyanosis for which he was intubated. Echocardiography showed no contractions of the left ventricle. Systemic circulation was provided by the right ventricle via shunting through the arterial duct. Left ventricular dysfunction was confirmed by electrocardiography and increased troponin T levels. Hemodynamics quickly improved, and the child could be weaned of the ventilator without residual problems. We concluded that the patient suffered from transient myocardial ischaemia. At 3 weeks of life, we performed delayed‐enhancement magnetic resonance imaging (DE‐MRI) of the heart which did not show signs of permanent macroscopic damage of the myocardium.
