Abstract

Unilateral absence of the pulmonary artery (UAPA) is a rare congenital cardiovascular anomaly with a wide array of symptoms. An 18-year-old man was referred to our hospital with dyspnea on exertion and central cyanosis. Transthoracic and transesophageal echocardiographic examinations revealed severe right ventricular enlargement, large main and left pulmonary arteries, severe pulmonary hypertension, and a large patent ductus arteriosus (PDA). The right pulmonary artery could not be seen; consequently, UAPA was considered. Computed tomography angiography confirmed the diagnosis. Our case is a rare condition with UAPA associated with patent ductus arteriosus, diagnosed in adulthood. It underscores the need for awareness of this anomaly for early diagnosis and treatment.
