Pulmonary valvular and infundibular atresia with intact ventricular septum

This case is one of combined infundibular and valvular pulmonary atresia with intact ventricular septum in which virtual absence of the tricuspid valve and a normal sized right ventricle were associated. Of particular interest was the presence of an endothelial-lined blind infundibular chamber. This finding, never previously reported, complicated surgical repair.
