The fetal heart is considered to be the most important and difficult part of fetal examination. The purpose of this book is to enable the reader firstly to find out whether the heart is normal or not, and secondly to diagnose the type of cardiac abnormality if present. To provide the skills and methodology to do this, the book covers basic anatomy and embryology, and explains what to look for, why and how. It also describes associated pathology (e.g. chromosomal abnormalities, syndromes) which the sonographer needs to know after a cardiac abnormality has been found.
