Pacemaker or electrode implantation for permanent pacing was performed on 4 cases with congenital heart disease during or after cardiac surgery. The first case with VSD+PH who suddenly developed complete A-V block approximately 9 months after VSD patch closure was treated with implantation of permanent pacemaker after 5 years observation.
The second case who originally had incomplete ECD developed into complete A-V block immediately after intracardiac repair. Permanent pacemeker was successfully implanted in this patient one month after the onset of complete A-V block.
In the third case who had Ebstein's anomaly with S-A block, intracardiac repair and pacemaker implantation were done simultaneously.
The fourth case who had Corrected TGA+VSD+ASD+PH with congenital complete A-V block was implanted with myocardial electrode for permanent pacing during open heart surgery. This electrode, however, has not been utilized yet, as he had remained asymptomatic without pacemaker implantation since then.
