Key result
Temporary pacemaker implantation through the umbilical vein was successfully used to manage congenital complete atrioventricular block in a 1.51 kg premature male neonate.
Why the study?
Transvenous temporary pacing in newborns is challenging due to risks of vessel injury, thrombosis, and technical difficulty placing leads in the right ventricle.
Case Report (n=1)
Temporary pacemaker implantation via the umbilical vein is a feasible option for managing significant bradycardia and haemodynamic instability in low birth weight neonates with congenital complete heart block.
May offer feasible umbilical vein temporary pacing in low-birth-weight neonates with congenital heart block; leaves open prospective validation before wider use.
Congenital heart block is a rare and lethal condition in paediatric population associated with maternal connective tissue disorders and rarely with structural cardiac disease like atrioventricular canal defects with or without left isomerism and congenitally corrected transposition of great arteries. Pacing in neonate if indicated is generally accomplished by epicardial pacing systems. However, in cases of significant bradycardia and haemodynamic instability, temporary pacemaker implantation via transvenous approach remains as a suitable option. Despite the advances in percutaneous catheter interventions, use of transvenous pacing in newborn is extremely challenging due to inadvertent risk of vessel injury, thrombus formation and mortality, and most of the time technical inability to place the lead within the right ventricular cavity. We report a case of congenital complete atrioventricular block in a premature male with birth weight of 1.51 kg who was managed with temporary pacemaker implantation through umbilical vein.
