The diagnosis and management of congenital heart defects has rapidly evolved over the last few decades. In this third volume of the series entitled “Congenital Heart Defects: Decision Making for Surgery”, Antonio Corno provides an up-to-date and comprehensive presentation of the new role that cardiac CT and MRI will play in the management of congenital heart defects. He has been ably assisted by a cardiologist, Pierluigi Festa. The book provides a dazzling array of images derived by both techniques and covers the full range of congenital heart malformations. Both the pre-operative and post-operative usefulness of these techniques is presented: in the pre-operative period with regard to the details useful for choosing among all available surgical options; in the post-operative period for monitoring the follow-up and potential complications. There is no doubt that these techniques will be particularly helpful for older children and adults with congenital heart disease in assessing the late impact of a congenital heart malformation and the surgical repair or palliation which may have been undertaken years previously.
