Absence of the pulmonary artery

Disease definition

Unilateral absence of the pulmonary artery (UAPA) is a rare congenital great vessels anomaly that commonly presents by dyspnea, frequent respiratory infections, hemoptysis and high-altitude pulmonary edema. UAPA is often associated with congenital heart malformation (CHM, see this term). In the absence of associated cardiac malformation (isolated UAPA; IUAPA), the condition may be asymptomatic until adult age.
