CTICasesTakeuchi repair for ALCAPA
Imaging findings
CT shows an anomalous left coronary artery arising from the pulmonary artery (ALCAPA), treated surgically with a Takeuchi repair (intrapulmonary tunnel/baffle routing blood from the aorta to the LCA ostium). Subendocardial calcifications are present.
Key takeaways
The Takeuchi procedure is a surgical repair for ALCAPA used when the anomalous LCA cannot be directly reimplanted. A tunnel is created through the pulmonary artery to route systemic arterial flow to the LCA, but is prone to late complications like baffle stenosis or leak.
