Neonatal Cardiovascular Function after Antenatal Sildenafil for Severe, Early-Onset Intrauterine Growth Restriction: A Substudy of the STRIDER-NZAus Randomized Placebo-Controlled Trial.

We evaluated the effect of antenatal sildenafil on neonatal cardiovascular function in a subgroup of 27 infants of mothers participating in the STRIDER-NZAus randomized controlled trial. In this small study, we found no association between antenatal sildenafil and neonatal cardiac dysfunction including no pulmonary hypertension in exposed or unexposed infants.
