Transatrial repair of double-outlet right ventricle in infants.

In three infant cases of double outlet right ventricle (DORV), two with normally related great arteries (NGA) and one with side-by-side great arteries, a transatrial repair was carried out. In all three cases, the results were excellent. It is concluded that in the small baby with DORV with NGA and in DORV with side-by-side great arteries with a hypoplastic crista, a transatrial repair should be successful. This is dependent on the VSD being in the perimembranous (and, therefore, subaortic) location and on the absence of infundibular pulmonary stenosis. In all other varieties of DORV the repair should probably be done through the ventricle.
