**1. Introduction**

Prenatal diagnosis of congenital anomalies provides parents an opportunity to obtain prognostic information prior to birth, learn about treatment options before and after delivery, reach decisions concerning the management approach that is best for their family (e.g., whether to terminate pregnancy or undergo in utero intervention, if available; nonintervention), and plan for specific needs at birth [1].
