Esophageal erosion by a PDA occluder device following MAPC closure in tetralogy of Fallot

Year: 2026

Type: article

Abstract: Tetralogy of Fallot (TOF) is the commonest cyanotic congenital heart disease encountered in paediatrics. Major aortopulmonary collaterals (MAPCAs) often complicate TOF when surgical correction is delayed, and a transcatheter closure is commonly done prior to definitive surgery. Embolization of occluding devices is a known complication that typically occurs in the vessels or in cardiac chambers. We report a young boy who presented with 1-month dysphagia post-transcatheter closure of a large MAPCAs. Barium revealed a filling defect confirmed by endoscopy as an impacted occluding device in the oesophagus. It was surgically removed, and the boy was discharged well. This case highlights a rare but highly significant unreported complication.
