Absent pulmonary valve is a rare congenital heart defect. This anomaly is a combination of poorly formed pulmonary valve tissue and significant pulmonary valve insufficiency. This may cause pulmonary artery dilatation. Massive dilatation of pulmonary arteries may lead to extrinsic compression of bronchial airway. [1] [2] [3]

Possible associated abnormalities include;

Diagnosis

Symptoms can vary depending on associated defects, and may include:

Diagnostic Tests

Treatment
