Fig. 5B Images from ECG-gated CT scan of 52-year-old woman with
dextrocardia, situs inversus, and congenitally corrected transposition of
great arteries (TGA). Axial image at level of cardiac chambers shows that
morphologic left atrium (LA) is connected to a morphologic right ventricle
(RV), distinguished by prominent trabeculations along its septal surface.
Morphologic right atrium (RA) is connected to a morphologic left ventricle
(LV). Artifacts are caused by presence of pacemaker in left ventricle and
prosthetic valve replacement of inflow valve of right ventricle. (Arrhythmias
and tricuspid valve dysfunction are common complications of congenitally
corrected TGA.) Ventricles are in D-loop configuration.
