Unilateral absence of a pulmonary artery in absent pulmonary valve syndrome: a case report and review of literature.
A six-year-old boy presented to the Cardiology clinic with history of mild cyanosis and dyspnea on exertion from age 1. He had a to-and-fro murmur at the middle left sternal border. Chest examination was normal but chest x-ray showed a small left lung. Echocardiography established the diagnosis of tetralogy of Fallot (TOF) and absent pulmonary valve with severe pulmonary regurgitation and moderate stenosis at the pulmonary valve site. There was severe dilatation of the main and right pulmonary arteries. The left pulmonary artery (LPA) could not be seen. Angiography failed to show a LPA. This case of an absent LPA associated with absent pulmonary valve syndrome is discussed and the literature is reviewed.
