Tetralogy of Fallot with absent pulmonary valve syndrome is a rare variant of tetralogy of Fallot marked by severe pulmonary insufficiency in utero and significant, sometimes massive, dilation of the pulmonary arteries. This syndrome can be associated with airway abnormalities that can cause respiratory compromise. Patients who present with respiratory symptoms early in life continue to present a major clinical challenge associated with relatively high mortality rates, typically in the 20% to 30% range. A variety of surgical techniques have been developed to address absent pulmonary valve syndrome that may improve long-term outcomes.
