Echo in double-outlet right ventricle

Double Outlet Right Ventricle occurs when both great arteries arise predominantly from the right ventricle (usually defined as both great arteries arising >50% from the right ventricle).

• Evaluation of relationship of the great arteries and right ventricle
  • Possible orientations: normal, side-by-side (aorta to the right of the pulmonary artery)
• Evaluation of the ventricular septal defect
• Doppler evaluation of pressure gradients and presence of valvular regurgitation
• Associated anomalities, especially pulmonic stenosis but also:
  • Atrial Septal Defect
  • Subaortic Stenosis
  • Patent Ductus Arteriosus
  • Mitral valvular abnormalities
• Evaluation after repair

• Optimal views:
  • Parasternal long axis
  • Subcostal coronal view
  • Parasternal short axis
