Systemic semilunar valve regurgitation can be a life-threatening hemodynamic lesion in the neonate with congenital heart disease. Although congenital aortic stenosis remains a vexing problem, a number of interventions have been designed to provide relief. Unfortunately, procedures designed to provide a more competent systemic semilunar valve in the neonate are limited. The reproducibility of reparative techniques might be unpredictable, and prosthetics are limited to small-caliber homografts; both approaches require cardiopulmonary bypass. We describe our experience with a surgical technique that treats systemic semilunar valve regurgitation in the neonate without the need for cardiopulmonary bypass.
