Epicardial implantation of a dual-chamber pacemaker on the left heart is a feasible and effective strategy for infants with postoperative complete AV block and low birth weight.
May support left epicardial dual-chamber pacing in select low-birth-weight infants with postoperative AV block; hypothesis-generating and leaves broader adoption open.
Total atrioventricular (AV) block is inconvenient and serious complication of open heart surgery. Permanent total AV block requires the implantation of permanent pacemaker in order to allow normal hemodynamics and patient's survival. In infancy additional challenge is the surgical approach, the selection of electrodes and PM, as well as place of implantation. We are publishing case report of successful double-chamber DDD pacemaker implantation at an infant born with Fallot tetralogy and with low birth weight due to complete AV block after primary surgical correction of these congenital defects.
