Subclinical Left Ventricular Systolic Dysfunction due to Coronary Arterial Thrombosis in a Neonate with Hypoxic Ischemic Encephalopathy Undergoing Therapeutic Hypothermia.

• Routine clinical parameters are not reliable surrogates of “low cardiac output” in HIE. • TnECHO screening may identify subclinical myocardial dysfunction in neonates. • TH may positively modulate myocardial oxygen consumption in myocardial ischemia. • Rigorous echo training and collaboration with pediatric cardiology are imperative.
