Congenital unilateral absence of right pulmonary artery with VSD and wide aortopulmonary window in an adult patient: a case report.

Unlabelled: Unilateral absence of pulmonary artery (UAPA) is a very rare condition, with an estimated prevalence of 1 in 200,000 population, which is commonly associated with various cardiovascular anomalies or can occur in an isolated manner. Isolated cases survive to adulthood and remain asymptomatic, but they may frequently experience hemoptysis, repeated infections, or symptoms like dyspnea and chest pain. Due to the rarity of the disorder and its ambiguous appearance, diagnosis can be very challenging.
