The aorta arose from the right ventricle supported by a complete muscular infundibulum.
In some cases of complete transposition, both arterial valves are supported by complete muscular infundibulums.
It also appears that on the whole the patients with poorly formed infundibulum have small tricuspid valves.
The muscular outlet septum, and the "septal" components of the subpulmonary infundibulum, were absent.
With a hypoplastic, or absent infundibulum, the pulmonary trunk is tapered, and there is usually an element of muscular atresia in the infundibulum as well.
These are supported by the muscular infundibulum of the right ventricle.
It is interesting, however, that they measured the diameter of the infundibulum during systole and could, therefore, have used undersized balloons.
Another reason for not using the video images was the detection of marked changes in the width of the pulmonary infundibulum throughout the cardiac cycle.
