Origin of Both Great Vessels from the Right Ventricle

[origin of Both Great Vessels from the Right Ventricle (ii)].

Origin of both great vessels from the right ventricle associated with the trisomy-18 syndrome.

T HE FIRST descriptions of the trisomy-18 syndrome were in 1960 by Edwards,' Patau,2 and Smith3 and their associates. Although there was disagreement concerning which of the three pairs of chromosomes had an extra number, it now appears to be pair 18. The major malformations involve the skin, face, heart, and the central nervous, musculoskeletal, gastrointestinal, and urogenital systems. Overla...

Origin of both great vessels from the right ventricle without pulmonary stenosis.

AMONG the congenital malformations in t& which an abnormal relationship exists between the aorta and pulmonary trunk is that in which both of these vessels arise from the right ventricle. The only outlet for the left ventricle is a ventricular septal defect. Right ventricular infundibular stenosis may or may not be associated. These cases apparently are extremely rare,1-3 and only a few have be...

Transposition of the great vessels with hypoplasia of the right ventricle.

Eight cases are reported in which complete transposition of the great vessels was associated with varying degrees of hypoplasia of the right ventricle. In three, the correct diagnosis was suspected on the basis of certain electrovectorcardiographic findings and confirmed by selective angiography. Quantitative analysis of ventricular volumes and valve circumferences demonstrated that these cases...
