Abstract

Congenitally corrected transposition of the great arteries (CCTGA) is a rare congenital heart disease with an atrioventricular and ventriculo-arterial discordance in which the morphological right ventricle supports the systemic circulation and the morphological tricuspid valve is the systemic atrioventricular valve. Heart rhythm disturbances and ventricular dysfunction related to electromechanical dyssynchrony are common in adult congenital heart disease patients with a systemic right ventricle. Thus, these patients may require conventional pacemaker implantation, which in the presence of ventricular dysfunction and conduction disease may further compromise cardiac performance. Indeed, cardiac resynchronization therapy may be an effective treatment option for these patients. We report the case of a patient with CCTGA and moderate depression of systemic ventricular systolic function who developed a 2:1 atrioventricular block and was treated with cardiac resynchronization therapy.
