[Prenatal diagnosis of pulmonary valve stenosis and immediate neonal valvuloplasty].
There are few reports of prenatal diagnosis of severe pulmonary valvar stenosis (PVS). It affects 1/22,000 newborn and represents 8-10% of total congenital cardiac defects. Clinic


METHODS
we report a case of a neonate in which was prenatally detected a pulmonary valvar stenosis and was successfully corrected with early valvuloplasty. From a 36-Year-old woman sent to evaluation to the fetal maternal unit because a tricuspid valvar insufficiency detected at 36 gestation weeks (GW). A VPS was suspected before born and a pregnancy ended in programated caesarean delivery at 38 GW, obtaining a 3 kg male, in which early echocardiography reported a severe PVS, promptly was initiated prostaglandin E1 (PgE1) infusion avoiding patent ductus arteriosus (PDA) closure, following a percutaneus balloon dilatation valvuloplasty at 48 hours, improving cyanosis and transvalvular Doppler flow.


CONCLUSIONS
we report a neonate referred with an opportune prenatal diagnosis of tricuspid insufficiency and confirmed a severe PVS, PgE1 was infused immediately after born, allowing successfully balloon dilatation valvuloplasty in first 48 hours.
