Usefulness of multislice computed tomography angiography to evaluate intravascular stents and transcatheter occlusion devices in patients with d-transposition of the great arteries after mustard repair

Percutaneous interventions can treat long-term complications after Mustard atrial switch operation in patients with d-transposition of the great arteries (d-TGA), but follow-up for these procedures has not been established. Four patients with d-TGA and previous Mustard operation underwent percutaneous placement of covered stents to relieve superior and inferior vena caval baffle obstructions and leaks. At 6 to 13 months, assessment with 16-slice spiral computed tomography identified stent patency as well as lead placement and visualization of additional devices.
