Cardiac magnetic resonance imaging (CMR) can provide comprehensive anatomic and physiological information about the cardiovascular system. The review article describes the application of CMR to several simple congenital heart lesions: atrial septal defects and other interatrial communications, ventricular septal defects, patent ductus arteriosus, partially anomalous pulmonary venous connection, and coarctation of the aorta. The anatomy, clinical features, and management of these lesions are discussed. CMR techniques to evaluate patients with these lesions are described and relevant literature is reviewed.
