ResumoBased on 91 operated cases of VSD with AI and 67 biplane aortographies taken before surgical treatment, we have made a classification of this syndrome and have described our opinions on the aortographic aspects. Type 1 is subpulmonary VSD, which is further divided into subtypes a and b. Type 2 is infracristal VSD which is divided into subtypes a, b, and c. These two types, which are distinguished according to the position of the VSD, have two forms found in the lateral aortogram, as follows: (1) protruding aortic valve and sinus, and (2) nonprotruding aortic valve and sinus. Protruding AI is easily observed in aortography, and the protruding part frequently coincides with the position of the VSD as ascertained by operation. As to nonprotruding AI, however, aortography does not demonstrate the position of the deformed valve and the VSD, but can show only the grade of aortic regurgitation. Infundibular stenosis often accompanies this syndrome. This complication occurs mainly with Type 2 VSD with AI, but also occurs with Type 1 in a small number of cases. Of the cases associated with infundibular stenosis, AI is caused by the protrusion of the aortic valve and the sinus in some cases and by different factors in other cases.
