Cineangiographic study in 41 patients with double outlet right ventricle was performed. Segmental approach was utilized to describe the anatomical features. Atrial situs was inversus in 5 cases, ambiguous in 3 and solitus in the other cases. Atrio-ventricular (a-v) connections were biventricular in 34 and univentricular in 7. A common a-v valve was found in 2 cases. Mitral valve was imperforated in 1 and straddling in 1. The most frequent relationship between aorta and pulmonary artery was side by side (41.1%). Ventricular septal defect was subaortic in 14, subpulmonary in 9, double committed in 5 and non committed in 6. In 27 cases a double infundibulum was present; in 7 patients we described a subpulmonary conus only. Some nosological aspects of this congenital heart disease are discussed particularly in conformity with the surgical needs.

Abstract
Cineangiographic study in 41 patients with double outlet right ventricle was performed. Segmental approach was utilized to describe the anatomical features. Atrial situs was inversus in 5 cases, ambiguous in 3 and solitus in the other cases. Atrio-ventricular (a-v) connections were biventricular in 34 and univentricular in 7. A common a-v valve was found in 2 cases. Mitral valve was imperforated in 1 and straddling in 1. The most frequent relationship between aorta and pulmonary artery was side by side (41.1%). Ventricular septal defect was subaortic in 14, subpulmonary in 9, double committed in 5 and non committed in 6. In 27 cases a double infundibulum was present; in 7 patients we described a subpulmonary conus only. Some nosological aspects of this congenital heart disease are discussed particularly in conformity with the surgical needs.
