Abstract

New generation multislice computed tomography (CT) technology has changed the approach to non-invasive assessment of congenital heart disease, in both the pediatric and adult congenital heart disease populations. This is mainly because of rapid advances in spatial and temporal resolution and in post-processing capability. At our institution, CT with multiplanar and three- dimensional reconstruction has become a routine examination in the evaluation of congenital heart disease both in planning surgery, complex interventional catheterisations and for follow-up. It has proven to be an invaluable diagnostic and decision-aiding methodology in these settings, as a complement to echocardiography and increasingly as a substitute for diagnostic angiography (which is usually associated with higher dose radiation and longer sedation times, as well as occasional morbidity). The present article illustrates the current status of 64- slice CT in congenital heart diseases, including assessment of the aorta, the coronary arteries, the pulmonary arteries, the systemic and pulmonary veins, and other intra- and extracardiac malformations.
