A baffling case of inferior vena cava filter removal in a patient with transposition of the great arteries.

A 47-year-old man with a history of transposition of the great arteries after a Mustard atrial switch procedure and prior inferior vena cava filter placement for venous thromboembolism presented for removal before being listed for orthotopic heart transplantation in anticipation of cardiopulmonary bypass cannulation. The filter was retrieved using a right transjugular approach without disruption of his existing atrial baffle. Contingency planning in the event of unsuccessful baffle navigation included a transfemoral everted filter approach. A thorough understanding of unique patient anatomy and multidisciplinary team approach is critical to safe procedural intervention in patients with congenital cardiovascular anomalies.
