“Single ventricle” refers to a heterogeneous group of congenital cardiac malformations that is characterized by both the atria related to a functionally single ventricle. The purpose of this exhibit is  1. To understand the various entities that constitute single ventricle. 2. To understand the various surgical options and timings for single ventricle. 3. To illustrate the MR imaging appearances of several types of single ventricle. 4. To describe the key MRI findings which are vital in influencing management.  

1. Nomenclature 2. Cardiac MRI protocols  3. Sample cases: True single ventricle, Hypoplastic left heart, Double inlet LV/ RV, Mitral/tricuspid atresia,  AV canal defect, Heterotaxy 4. Review & illustration of key factors in anatomic characterization- Atrial situs; Ventricular situs; Great artery relationship, Atrioventricular relationship; AV connection (single, double, or common); AV morphology (straddling/overriding); morphologic LV vs RV; Rudimentary vs functioning ventricles 6. Imaging goals -anatomy, ventricular size, valve function, flow 7. Rationale and role of imaging data in management  

Evaluation of functional single ventricle by MRI requires a thorough understanding of the anatomy and hemodynamics. The purpose of MRI is to delineate the anatomy, physiology and function and to aid in management.
