Early Detection of Isolated Transient Right Ventricular Hypertrophy in a Term Neonate: the Neonatologist's Role.

Right ventricular hypertrophy (RVH) is a rare finding in the neonatal age. Multiple pathological conditions are associated with the development of RVH, such as metabolic diseases, hereditary disorders and premature closure of the ductus arteriosus during the intrauterine life. Transient isolated RVH may be due to perinatal factors such as perinatal distress and corticosteroid treatment of preterm neonates with bronchopulmonary dysplasia. We report a case of a term neonate, appropriate for gestational age presenting transient hypertrophy of the right ventricle, who was diagnosed with echocardiography applied by neonatologists on the first day of life.
