Magnetic Resonance Imaging in Congenital Heart Disease

Pierluigi Festa and Lamia Ait-Ali

Abstract

Magnetic Resonance Imaging (MRI) has emerged as a valuable non-invasive diagnostic tool in congenital heart malformations providing anatomical and functional data regardless of patient’s size and quality of thoracic window. This technique is particularly indicated to avoid cardiac catheterization in post-surgical adult patients in whom the echocardiographic window is often poor. MRI is able to provide both accurate 3-dimensional images of the cardiovascular system as well as precisely quantify volumes and mass of the cardiac chambers and functional data of any single segment of the heart. MRI is now considered a Class I indication in pediatric or adult patients with congenital heart malformations. It is able to define morphological data of cardiac malformation and its functional consequences at the same time. This paper summarizes the most relevant technical aspects of MRI in congenital heart disease and reports on useful protocols to evaluate the most common malformations.
