VENTRICULAR SEPTAL DEFECT IN TETRALOGY OF FALLOT

The ventricular septal defect in 6o cases of tetralogy of Fallot was examined by right ventriculography. Left heart angiography was performed in 12 cases.

The infracristal defect was demonstrated in 45 cases and the subpulmonary defect in 15 cases.

The diagnosis of infracristal ventricular septal defect is established without difficulty, when the crista supraventricularis forms the upper outline of the defect in the lateral view, and when the crista separates the 2 ventricular outflow tracts as a tongue-like radiolucency in the anteroposterior view. In cases where the crista is not clearly shown, it is necessary to examine the defect in relation to the aortic cusps and pulmonary valve.

Left heart angiography gives the complementary findings in determining the location of the ventricular septal defect.

One case of subpulmonary defect is reported in which herniation of the right aortic cusp partially filled the defect.
