Pulmonary vein stenosis

Pulmonary vein stenosis is extremely rare, progressive and usually fatal, if left untreated.

Isolated stenosis of pulmonary veins, as they enter into the left atrium, is a rare congenital cardiac abnormality that has significant impact on clinical outcome.

Diagnosis is difficult to suspect, especially in the absence of other cardiac abnormalities.

Symptoms and clinical signs of pulmonary vein stenosis are very similar to those of chronic lung disease and are very difficult to differentiate.
