title: Massive Gastrointestinal Bleed as Presentation for Previously Undiagnosed Coarctation of Aorta.
abstract: BACKGROUND
  Coarctation of the aorta is a common congenital heart lesion with a known complication of collateral vessel formation if left untreated.
  
  
  OBJECTIVE
  To alert pediatric emergency physicians of a rare and life-threatening presentation of previously undiagnosed congenital heart disease in the adolescent.
  
  
  METHODS
  We discuss the case of a 15-year-old boy who presented with hypertension and massive upper GI bleed due to aortoenteric fistula formation associated with undiagnosed coarctation of the aorta. There are no other reports of a similar presentation in the literature.
