Data regarding cardiac resynchronization therapy (CRT) in pediatric patients are limited. The first reported use of CRT in a young patient with congenital heart disease showed promising early results with improvement in New York Heart Association classification, aerobic capacity, and ventricular contractility 1 month after implant.<sup>1Rodriquez-Cruz E., Karpawich P.P., Lieberman R.A., Tantengco M.V.
