CTICasesTransposition of Great Arteries Post-Arterial Switch with Lecompte Maneuver and Main Pulmonary Artery Compression
Imaging findings
Post-operative imaging shows the anatomical rearrangement of the great arteries following an arterial switch procedure for transposition of the great arteries. The pulmonary arteries are draped over the aorta, consistent with the Lecompte maneuver. Decades later, the main pulmonary artery is compressed by the slightly enlarged aorta.
Key takeaways
This 48-year-old woman is one of the very few surviving early recipients of the Jatene arterial switch procedure for TGA. The Lecompte maneuver, where pulmonary arteries are swung over the (now anterior) aorta to prevent compression, is often misattributed to Jatene. The case demonstrates a late complication of this surgery, with chronic main pulmonary artery compression requiring further intervention.
