Abnormal pulmonary artery branching in tetralogy of Fallot with "absent" pulmonary valve.
Microangiographic postmortem study in a case of tetralogy of Fallot with so-called absent pulmonary valve disclosed an abnormal branching pattern of the intrapulmonary arteries, but failed to detect any compression of intrapulmonary bronchi as a consequence of the distorted segmental arteries. The case also featured the absence of the ductus arteriosus, which should be considered a basic associated anomaly in the development of this malformative complex.
