Fetal Septal Defects

Darren Hutchinson and Ricardo Palma-Dias

Abstract

The frequency of the different fetal septal defects and their presentation prenatally is described, including atrial septum defects (ASDs), ventricular septum defects (VSDs) and atrioventricular septum defects (AVSDs). Embryology of the defects and the association with underlying aneuploidy and genetic syndromes are discussed. Image findings in the fetal period are presented alongside diagrams to aide comprehension of the ultrasound views. A brief summary of prognosis and postnatal course of these conditions is also included.
