3- and 4-Dimensional Flow CMR in D-Transposition of the Great Arteries After Atrial Switch Operation

Year: 2025

Type: article

Abstract: A 19-year-old man with D-transposition of the great arteries and pulmonary stenosis underwent atrial switch operation and pulmonary valvotomy in infancy. He was lost to follow-up and presented with multiple respiratory infections. An echocardiogram was inconclusive due to poor windows. Cardiac magnetic resonance (CMR) was performed using ferumoxytol 3-dimensional whole heart and 4-dimensional flow pulse sequences, which demonstrated this patient's complex anatomy and physiology. CMR revealed severe pulmonary venous baffle obstruction. A 3-dimensional printed model was created from the CMR and provided key information for planning the complex catheterization approach required to stent the pulmonary venous baffle.
