Editing Tetralogy of Fallot (section)

=== Additional anomalies ===

In addition, tetralogy of Fallot may present with other anatomical anomalies, including:<ref name="Francois_2016"/>{{rp|66–68}}<ref>{{cite journal | vauthors = Hennein HA, Mosca RS, Urcelay G, Crowley DC, Bove EL | title = Intermediate results after complete repair of tetralogy of Fallot in neonates | journal = The Journal of Thoracic and Cardiovascular Surgery | volume = 109 | issue = 2 | pages = 332–342, 344; discussion 342–343 | date = February 1995 | pmid = 7531798 | doi = 10.1016/S0022-5223(95)70395-0 | doi-access = free }}</ref>

Tetralogy of Fallot with [[pulmonary atresia]] (''pseudotruncus arteriosus'') is a severe variant<ref name="pmid19079949">{{cite journal | vauthors = Farouk A, Zahka K, Siwik E, Erenberg F, Al-Khatib Y, Golden A, Karimi M, Uddin M, Hennein HA | display-authors = 6 | title = Individualized approach to the surgical treatment of tetralogy of Fallot with pulmonary atresia | journal = Cardiology in the Young | volume = 19 | issue = 1 | pages = 76–85 | date = February 2009 | pmid = 19079949 | doi = 10.1017/S1047951108003430 | doi-broken-date = 2024-11-14 | s2cid = 2529238 }}</ref> in which there is complete obstruction (atresia) of the right ventricular outflow tract, causing an absence of the pulmonary trunk during embryonic development.<ref name="Francois_2016"/>{{rp|67–68}} In these individuals, blood shunts completely from the right ventricle to the left where it is pumped only through the aorta. The lungs are perfused via extensive collaterals from the systemic arteries, and sometimes also via the ductus arteriosus.<ref name="Francois_2016"/>{{rp|67–68}}
