Pacing in preterm with hydrops fetalis due to congenital complete heart block.

Hydrops fetalis due to congenital complete heart block (CCHB) is a rare condition. The outcome of the preterm fetus with hydrops fetalis due to CCHB is poor, and is frequently associated with significant morbidity and mortality. The management of this condition is difficult. We report our experience in a hydropic preterm using staged pacing by applying left ventricular epicardial pacing with a temporary pacemaker and subsequently, left ventricular epicardial pacing with a permanent pacemaker.
