Cardiac hypertrophy in the neonatal period is usually associated with other congenital defects of the circulatory system. Isolated ventricular hypertrophy can be difficult to evaluate and manage. We present 17 neonates with increased ventricular wall thickness without congenital malformations according to echocardiography during the neonatal period. The echocardiographic findings were defined as either concentric or predominantly septal hypertrophy. Doppler signs of ventricular outflow obstruction were found in six babies. The material consisted of preterm infants with steroid-treated bronchopulmonary dysplasia, metabolic disorders, perinatal infections, hypertrophic cardiomyopathy and babies with no identified underlying disorder. Six out of 17 patients died before the age of 8 months: all three babies with hypertrophic cardiomyopathy, one with toxoplasmosis and two out of four infants with steroid-treated bronchopulmonary dysplasia. It was not possible to predict the outcome from the initial clinical examination or from the first echocardiographic investigation. Ventricular wall thickness and outflow obstruction may undergo significant and rapid changes, and thus we recommend repeated echocardiographic examinations.
