[Cardiac resynchronization in a patient with congenitally corrected transposition of the great arteries]

Abstract

Congenitally corrected transposition of the great arteries is a rare heart defect that can be associated with systemic ventricular dysfunction and conduction disturbances. The use of cardiac resynchronization therapy in patients with congenital heart disease is not fully established. The authors report a case of cardiac resynchronization therapy in a 31-year-old woman with a history of congenitally corrected transposition of the great arteries and heart failure, who had undergone two heart surgeries and had a DDDR pacemaker implanted. To our knowledge this is the first case reported in Portugal of cardiac resynchronization therapy by transvenous access in a patient with congenitally corrected transposition of the great arteries.
