Successful implantation of a bipolar epicardial lead and an autocapture pacemaker in a low-body-weight infant with congenital atrioventricular block: report of a case.

A permanent pacemaker system was successfully implanted into a low-body-weight infant with congenital atrioventricular (AV) block, using a bipolar epicardial CapSure Epi lead and an autocaptured Pacesetter Solus-micro VVIR pacemaker. The calculated life span of the pacemaker generator is 5 years with a heart rate of 120/min and an output of 1.2 V (0.31 ms), and fortunately, its threshold was autocaptured. Thus, we can conclude that the combination of a steroid-eluted bipolar epicardial lead and the smallest possible autocaptured pacemaker generator is most suitable for a neonate or young infant.
