Double outlet right ventricle with pulmonary stenosis.

Double outlet right ventricle with pulmonary stenosis.

Although transposition of the great vessels is a well-known clinical and pathological entity, the partial transposition complex, resulting in the origin of both the aorta and the pulmonary trunk from the right ventricle, is rare. The association of this malformation with pulmonary stenosis has been described previously (Braun et al., 1952; Witham, 1957; Neufeld, DuShane, and Edwards, 1961; Morg...

Double Outlet Right Ventricle with Pulmonic Stenosis.

The results of complete repair of double-outlet right ventricle with pulmonic stenosis in 22 Mayo Clinic patients were analyzed. The overall mortality rate was 32%. Since 1960, the mortality rate has been reduced to 16%. Anomalies of the distribution of the right coronary artery, a second ventricular septal defect of the atrioventricular canal type, and significant residual pulmonic stenosis we...

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 right ventricle associated with persistent common atrioventricular canal and pulmonary stenosis.

A case of a month-old baby admitted for dyspnea and cyanosis, is described. His past history consisted of only mild cyanosis during crying. On physical examination nail beds and lips were cyanotic; on heart auscultation the pulmonary second sound was single. The chest X-ray showed a decreased pulmonary vascularity; the ECG demonstrated extreme right axis deviation (-170 degrees). Capillary gas ...
