Abstract

Although echocardiography and angiography still are the most widely used imaging modalities, magnetic resonance imaging (MRI) can be a valuable noninvasive adjunct to plan effective management of congenital heart disease. MRI offers particular advantages in patients who underwent surgical repair of tetralogy of Fallot (TOF). In the follow-up of these patients, an imaging technique is required to provide information on a) residual anatomic problems, b) the importance of a possible residual pulmonary stenosis, c) the amount of pulmonary regurgitation and d) systolic and diastolic biventricular size and function. Transthoracic echocardiography often has limitations in these patients, due to poor image quality especially in adult patients, and does not allow quantitative evaluation of the right ventricular function and the amount of pulmonary regurgitation. MRI is actually the only imaging technique that provides quantitative information on residual pulmonary regurgitation, an important determinant of outcome after repair of TOF, and is very useful in the follow-up of these patients, also for the timing of an eventual pulmonary valve replacement. Moreover, gadolinium-enhanced MRI has become an attractive technique in visualizing the pulmonary vessels in an angiographical format. MRI however has limitations in small children; to obtain adequate images, sedation or general anesthesia is needed. Therefore transthoracic ultrasound remains often the first-line noninvasive method in young children.
