Bilateral semilunar valvotomies using inflow occlusion in a neonate.

The case of a neonate with critical pulmonary and aortic valve stenosis who underwent successful sequential valvotomies using one period of inflow occlusion is reported. This valvotomy technique performed in critically ill neonates, if carried out expeditiously, can result in the same degree of success as when used for single valvotomies.
