This study analyzed risk factors for delivering low birth weight neonates in pregnancies complicated by congenital valvular heart disease. The study collected data from 142 pregnancies with congenital heart disease over one year. Preterm birth was found to be a significant risk factor for low birth weight, with an adjusted odds ratio of 0.052. While multiparity showed a non-significant increased risk of low birth weight. The study concluded that preterm birth in women with congenital valvular heart disease is a risk factor for delivering low birth weight neonates.
