CTICasesL-Transposition of the Great Arteries
Imaging findings
A patient in her late 30s was initially suspected of having peripartum cardiomyopathy. CT revealed l-transposition (SLL), where the aorta is anterior and to the left, and the systemic ventricle is the morphologic right ventricle.
Key takeaways
Congenitally corrected transposition can remain undiagnosed until adulthood. Echo findings of ventricular dilation can mimic cardiomyopathies, but cross-sectional imaging reveals the true morphologic anatomy.
