Double-outlet right ventricle
Macroscopic appearance
  • the pulmonary artery and the aorta arise both from the morphologic right ventricle
  • there is a ventricular septal defect, its location is used to define the subcategory of the defect
  • various malformations are commonly associated: pulmonary stenosis is frequent, mitral atresia, dextrocardia or AV septal defect are less common
  • the hemodynamics is complicated and depends on the associated defects and localisation of the ventricular septal defect
  • rare malformation
  • double outlet left ventricle is the analogous malformation on the left side, extremely rare
