Complete atrioventricular block in an adult with congenitally corrected transposition of the great arteries with interrupted inferior vena cava

J Res Med Sci. 2012 Aug;17(8):808-10.

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.

Keywords: Complete atrioventricular block; congenitally corrected transposition of the great arteries; interrupted inferior vena cava.
