Stress Transient Hypertrophic Cardiomyopathy and B-Type Natriuretic Peptide Role

Pediatric Cardiology, 05/16/2012

This report describes a transient hypertrophic cardiomyopathy with right–ventricle outlet tract obstruction (RVOTO) induced by perinatal stress due to a major surgical procedure in a female newborn with congenital abnormalities. On day 10, she presented with heart failure, abnormal B–type natriuretic peptide (BNP), and an echocardiogram showing normal wall thickness. An in–hospital follow–up echocardiogram showed biventricular hypertrophy and RVOTO.
