There has been a rapid increase in the practice of interventional catheter treatment of congenital heart disease. Catheter retrieval of embolized cardiac devices and other foreign bodies is essential, yet no large studies have been reported in the paediatric population. Retrospective 15-year review of all children who underwent transcatheter foreign body retrieval in a tertiary cardiac centre from January 1997 to September 2012. Transcatheter retrieval of foreign bodies from the cardiovascular system was attempted in 78 patients [median age 4 (0.02-16) years and median weight 15 (1.7-74) kg] including 46 embolized devices. Transcatheter retrieval was successful in 70/78 (90%), surgical retrieval was required in 6. In two patients, small embolized coils were left in situ. Gooseneck snare was the most commonly used retrieval device. Median procedure and screening times were 90 (15-316) and 31 (2-161) min, respectively. There were no procedural deaths. Transient loss of foot pulses occurred in 5 and 2 patients required blood transfusion. Transcatheter retrieval of cardiovascular foreign bodies can be performed safely in the majority of children thus obviating the need for surgery. It is essential to have a comprehensive inventory of retrieval equipment and interventional staff conversant with its use.
