Anatomically Corrected Malposition Or Double Outlet Right Ventricle?

Double outlet right ventricle with 1-malposition of the aorta.

Four patients are described with a recently recognized variant of double outlet right ventricle. Clinical examination favoured tetralogy of Fallot, but the chest X-ray suggested corrected transposition. Catheterization and angiocardiography showed that the aorta was to the left of the main pulmonary artery, and both arose from a normally positioned morphological right ventricle. Egress of blood...

double-outlet right ventricle

In a previous study the possibility that tetralogy of Fallot and transposition of the great arteries may arise as a result of embryonic arrests in the normal rotation of the junction of the outflow tract and the great arteries was investigated. The results suggested that the development of other transposition complexes such as double-outlet right ventricle might also be related to arrests in th...

Anatomically corrected malposition of great arteries

Anatomically corrected malposition of great arteries (ACMGA) is a rare form of congenital heart disease in which the great arteries arise above the anatomically correct ventricles but have abnormal spatial relationship. We report the case of a 26-year-old female with ACMGA and tunnel type of subaortic obstruction. The abnormal relationship and segmental arrangement necessitates systematic appro...

Double outlet right ventricle: aetiologies and associations.

BACKGROUND Double outlet right ventricle (DORV), a clinically significant congenital heart defect, occurs in 1-3% of individuals with congenital heart defects. In contrast to other major congenital heart defects, there are no systematic or comprehensive data regarding associations, aetiologies, and pathogenesis of DORV. We analysed reported cases in the medical literature to address these issue...
