Abstract :
A 56-year-old man got admitted as he was suffering from dizziness for 3 days. Electrocardiogram (ECG) showed complete
atrioventricular (AV) block with ventricular rhythm of 35/min. We found that he had no inferior vena cava (IVC) which drained into
right atrium in the middle of temporary pacing lead insertion. Venous drainage into superior vena cava from dilated azygos vein was
identified after venogram. Echocardiogram revealed a congenitally corrected transposition of the great arteries (CCTGA). Chest
computed tomography (CT) angiogram revealed AV and ventriculoarterial discordance with reversed ventricles and interrupted
IVC with azygos continuation. DDD pacemaker was implanted via left axillary vein without any problem.
