Abstract
Tetralogy of Fallot (ToF) is the most common cyanotic congenital heart disease. Cyanotic spells occur more frequently after infancy in unrepaired cases. Acute esophageal necrosis (AEN) is a rare disease that causes circumferential mucosal necrosis in the distal esophagus. We report the case of a 26-year-old man who was admitted due to coffee-ground emesis, black stools, and decreased oxygen saturations. The patient had an unrepaired ToF and a congenital portosystemic venous shunt. An upper gastrointestinal endoscopy revealed AEN, which could be due to unstable hemodynamics of cyanotic spells. This is the first adult case presenting these 2 conditions occurring simultaneously.
