Double Outlet Right Ventricle: Morphology and Function

Cross-sectional imaging with multislice CT (MSCT) or magnetic resonance (MR) is one of the mainstays of preoperative assessment of many complex congenital heart diseases (CHD) in current clinical practice, one of them is double outlet of right ventricle (DORV). DORV is a type of the conotruncal anomalies that encompasses a wide spectrum of anatomic malformations in which both the aorta and pulmonary arterial trunk arise entirely or predominantly from the morphological right ventricle (RV). The purpose of this chapter is to understand the spectrum of DORV and associated types of ventricular septal defect (VSD) on imaging.
