1. To review CT and MR features of ventricular septal defects (VSDs) 2. To highlight the classification of VSDs based on location in the septum 3. To review associated conditions with different types of VSDs 4. To demonstrate unusual complications of VSDs, including double chamber right ventricle and aortic insufficiency from the Venturi efffect

This exhibit will center on illustrating CT and MR techniques for the evaluation of VSDs and on classifying VSDs based on location (perimembranous, inlet, muscular and supracrystal). The associations with the various types of VSDs will be highlighted (endocardial cushion defect, isolated, conotruncal abnormalities), as well as some of the complications, including double chamber right ventricle, windsock or aneurysm and Venturi effect resulting in aortic insufficiency.

Knowledge of the variety of VSDs, their anatomic locations and their associations are important for radiologists to understand in order for the actual detection of the VSD and any important, associated finding(s).
