Double-outlet right ventricle with tunnel from left ventricle to aorta

Double outlet right ventricle.

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...

Double outlet left ventricle.

A case, the sixth, ofdouble outlet left ventricle is reported, the diagnosis being made by cardiac catheterization and angiocardiography. Though the existence of such a malformation has been questioned on embryologicalgrounds, double outlet left ventricle must now be regarded as a recognized cardiac anomaly. The embryological significance of this case is discussed and it is suggested that the m...

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 with long survival.

The entity of double outlet right ventricle is being increasingly recognized in recent years (Neufeld, DuShane, and Edwards, 1961a; Neufeld et al., 1961b, 1962; Morgan et al., 1962; Mehrizi, 1965; Venables and Campbell, 1966). The oldest patient in the series reported by Mehrizi (1965) was 22 years and in the 10 patients of Venables and Campbell (1966) the oldest was 9 years. We report a patien...
