Transcatheter treatment of IVC channel obstruction and baffle leak after mustard procedure for d-transposition of the great arteries using amplatzer ASD device and multiple stents

A patient with d-transposition of the great arteries who underwent the Mustard operation at one year of age developed intermittent symptomatic cyanosis as a young adult. Evaluation demonstrated a large baffle leak with bidirectional flow and stenosis of the intra-atrial IVC baffle channel. Initially, a single stent was placed to relieve the obstruction, followed by placement of an Amplatzer septal occluder device which assumed suboptimal position after release. Placement of additional stents securely repositioned the ASD device into excellent position, resulting in complete occlusion of the baffle leak and no residual obstruction in the IVC channel.
