Echo in Double Outlet Right Ventricle
Introduction
Editors-in-Chief: Eli V. Gelfand, MD and Keri Shafer, MD (Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA)
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
