Pulmonary artery banding

Pulmonary Artery Banding (PAB) was introduced by Muller and Danimann in 1951 as a surgical technique to reduce excessive pulmonary blood flow in infants suffering from congenital heart defects. PAB is a palliative operation as it does not correct the problems, but attempts to improve abnormal heart function, relieve symptoms and reduce high pressure in the lungs. The use of PAB has decreased over the years due to advancements in definitive surgical repairs, however PAB still has widespread clinical use. PAB is commonly used in patients when definitive surgical repair is not feasible.
