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).
Echo functions in DORV
- 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
Special Echo techniques in DORV
- Optimal views:
- Parasternal long axis
- Subcostal coronal view
- Parasternal short axis
