“…Although, the epicardial approach remains essential in children with congenital heart disease in whom venous access is not available, a transvenous lead system is most commonly advocated in children of adequate size (Fortescue et al, 2004;Kammeraad et al, 2004). An endocardial pacing system is preferably implanted in children weighing more than 15 kg (Fortescue et al, 2004;Alexander 2004), although implantation at a smaller patient size has been reported (Kammeraad et al, 2004;Sachweh et al, 2000). Several patient and lead related features should be weighed before an optimal decision regarding an epicardial or endocardial lead system can be made.…”
