LA85.2 Double outlet right ventricle
|
Introduction
- 1-1.5% of Congenital Heart Disease
- Both large arteries arise wholly or mainly from the right ventricle.
- Arrangement of the atrioventricular valves and the ventriculoarterial connections are variable.
- Clinical manifestations variable.
If the pulmonary trunk retains its location above the morphologically right ventricle, then the end result will be yet another variant of double outlet right ventricle, specifically with a subpulmonary interventricular communication. This variation is known as the Taussig-Bing malformation.

Anatomy
A human heart with double outlet from the right ventricle, but with a doubly committed interventricular communication. The proximal outflow cushions have fused, but have failed to muscularise. Because of this, the outlet septum, derived from the fused cushions, is fibrous and hypoplastic.
Double Outlet from Right Ventricle
Genetics
HAND1
Heart-And Neural Crest Derivatives-Expressed 1 (HAND1) gene located at 5q32, is a 215-amino acid protein transcription factor that contains a bHLH region and several potential phosphorylation sites. The mouse and human sequences share 93% overall sequence identity.
