Double-outlet right ventricle is a complex congenital heart disease that encompasses various common and rare subtypes. Surgical management of these patients needs to be individualized owing to extremely variable morphology and hemodynamics. Imaging plays a crucial role in determination and characterization of outflow tract morphology. The assessment of ventricular septal defect routability with identification of associated anomalies has therapeutic implications in these patients. Multislice computed tomography with advanced 3-dimensional postprocessing techniques and dose-reduction strategies is invaluable in defining the anatomy and morphology of double-outlet right ventricle with simultaneous assessment of associated anomalies.
双出口右心室是一种复杂的先天性心脏病，包括各种常见和罕见的亚型。由于形态和血液动力学变化极大，这些患者的手术管理需要个体化。影像学在确定和描述流出道形态方面起着至关重要的作用。评估室间隔缺损的可通性，并识别相关异常，对这些患者具有治疗意义。多层螺旋 CT 结合先进的三维后处理技术和剂量减少策略，对于明确双出口右心室的解剖和形态，并同时评估相关异常，具有重要价值。
