Coarctation of the aorta in the newborn: a clinical study.

Abstract

The clinical findings and presentation in nine consecutive neonates in whom coarctation of the aorta was diagnosed over a period of two years were reviewed. Coarctation of the aorta constituted 16% of all infants with congenital cardiovascular malformations admitted to the Neonatal Intensive Care Nursery. The mean age on admission was 8.3 days. The admission findings included absent femoral pulses, 5; feeble femoral pulses, 4; differential blood pressure between upper and lower extremities, 9; congestive heart failure, 8; hypertension, 2; and failure to thrive, 1. Five of the infants died owing to refractory congestive heart failure at the mean age of 10.2 days. It is emphasized that palpation of the femoral pulse should be a routine examination in the neonatal period in order to detect coarctation of the aorta and that surgical intervention may be considered in cases refractory to medical management.
