Key result
Epicardial VVIR pacemaker treats congenital complete heart block in a CCTGA neonate, restoring 120 bpm.
Why the study?
Congenital complete heart block is rare in neonates and typically caused by maternal lupus, but it can more rarely be associated with congenitally corrected transposition of the great arteries.
Case Report (n=1)
No
Highlights a rare case of congenital complete heart block associated with congenitally corrected transposition of the great arteries, emphasizing that maternal lupus is not the only cause.
Pacemaker insertion stabilizes neonates with CCHB and ccTGA; extends sparse case reports but leaves optimal long-term management open.
Congenital complete heart block (CCHB) is a rare cardiac disorder in neonates and maternal lupus is the most common cause. More rarely, CCHB can be associated with congenitally corrected transposition of the great arteries. In this case, the neonate was born via emergency caesarean section due to bradycardia. Post-natal electrocardiogram and echocardiography confirmed the diagnosis. A pacemaker was inserted and the baby was kept under follow-up.

Sankhyan et al. (2023) conducted a case report in Congenital complete heart block and congenitally corrected transposition of great arteries (n=1). Permanent VVIR mode epicardial pacemaker was evaluated on Heart rate. Implantation of a permanent VVIR mode epicardial pacemaker successfully treated congenital complete heart block in a neonate with CCTGA, increasing heart rate to 120 bpm.
