Transient gastric outlet obstruction and tetralogy of Fallot: a true association or a coincidental finding?

ABSTRACT

Infants suffering from congenital heart anomalies who are receiving intravenous prostaglandins may present with gastric outlet obstruction. We describe a newborn with tetralogy of Fallot who was not being treated with prostaglandins and presented with gastric outlet obstruction. The typical clinical and radiological signs of infantile hypertrophic pyloric stenosis resolved spontaneously within several days. We suggest that there may be an association between cyanotic heart disease and gastric outlet obstruction unrelated to the use of prostaglandins.
