Does a two-stage pacemaker implantation strategy facilitate permanent pacemaker placement in low-birth-weight infants with CAVB?
A two-stage pacemaker implantation strategy is successful in facilitating permanent pacemaker placement in low-birth-weight infants with CAVB.
Infants born with complete atrioventricular block (CAVB) and fetal bradycardia are frequently born with low birth weight. Three low-birth-weight CAVB infants underwent temporary pacemaker implantation, followed by permanent single-chamber pacemaker implantation at median body weights of 1.7 and 3.2 kg, respectively. All infants caught up with their growth curves and had >3 years of estimated residual battery life. This two-stage strategy was successful in facilitating permanent pacemaker implantation in low-birth-weight babies. Placement of single-chamber pacemaker on the apex of the left ventricle appears to be associated with longer battery lifespan.
Fuchigami et al. (Thu,) conducted a case report in Complete atrioventricular block (CAVB) and fetal bradycardia (n=3). Two-stage pacemaker implantation (temporary followed by permanent) was evaluated on Growth curve catch-up and estimated residual battery life. A two-stage strategy of temporary followed by permanent pacemaker implantation was successful in 3 low-birth-weight infants with CAVB, resulting in growth catch-up and >3 years of battery life.
