We prospectively analyzed the results of extracorporeal membrane oxygenation (ECMO) done in our Pediatric Cardiac Unit from January to December 2007. We present a series of nine patients who required ECMO after open heart surgery for congenital heart disease (CHD). The overall survival rate of these patients was 77.8%. The survival rate was 100% in patients who were electively put on ECMO after intracardiac repair for tetralogy of fallot, 50% in patients who were put on ECMO following the arterial switch operation and 50% in patients who were put on ECMO after VSD closure. Our results seem to suggest that patients placed on ECMO electively rather than after a cardiac arrest posts congenital cardiac surgeries have a better outcome.
