Abstract
Septal defects are the most common congenital heart defects. Although often being classified as simple congenital cardiac defects, many of these anomalies are of hemodynamic importance. Cardiovascular magnetic resonance (CMR) imaging is able to describe the anatomical details of atrial and ventricular septal defects as well as their associated anomalies. In addition, CMR provides clinically important information about the hemodynamic significance of a particular defect by enabling accurate shunt quantification and precise measurement of atrial and ventricular volumes. In this chapter, the different atrial and ventricular septal defects and the CMR techniques for their evaluation are described.
