Abstract
Congenitally corrected transposition of the great arteries (CCTGA) is a rare form of congenital heart disease characterised by atrioventricular as well as ventriculoarterial discordance. It is usually associated with a variety of severe intracardiac defects. Few patients with this abnormality survive past 50 years. An 80 year old woman was admitted to the hospital because of mild congestive heart failure. Cardiac examination revealed a 4/6 holosystolic and a 2/6 decrescendo diastolic murmur at the left sternal border. Radiography, echocardiography, and computed tomography confirmed newly diagnosed CCTGA without associated intracardiac defects. Keywords: corrected transposition of the great arteries; adult congenital heart disease; natural history; congenital heart disease

Figure 1 .
Chest radiograph showing an enlarged cardiac silhouette, a prominent right hilus, and absence of a pulmonary artery segment.
Figure 2 .
Apical view showing a topographically left sided right ventricle with the crista interventricularis (arrow), heavy trabeculations, and a tricuspid valve (double arrowheads), which is located more apically than the mitral valve (single arrowheads). The left ventricle (LV) supplies the pulmonary artery, identified by its bifurcation into a right (RPA) and left pulmonary artery (LPA). RA, right atrium.

Spiral computed tomography of the chest showing a calcified ascending aorta (single arrowhead) located anteriorly and to the left of the main pulmonary artery (double arrowheads). In addition, the proximal segments of the two vessels run in parallel. Arrow points to descending aorta.
