Prenatal diagnosis of crossed pulmonary artery with tetralogy of Fallot
and right aortic arch: A rare case report and literature review
Crossed pulmonary arteries (CPA) is an unusual malformation
characterized by abnormal origination of the pulmonary arteries from the
main pulmonary artery (MPA), which is usually associated with complex
cardiac pathologies and chromosomal abnormalities. We report a case of
crossed pulmonary artery (CPA) associated with tetralogy of Fallot
(TOF), right aortic arch (RAA), and absence of ductus arteriosus.
Sonographic findings, complicated malformations, genetic anomalies,
differential diagnosis, and prognosis analysis are discussed. Although
the isolated CPA is relatively asymptomatic, when it is accompanied by
other cardiac anomalies, the prognosis needs to be reevaluated.
