Pulmonary artery banding is a palliative heart surgery, introduced by Muller and Dammann in 1951, that narrows the pulmonary artery with a band to reduce excessive blood flow into the lungs of infants born with congenital heart defects. The operation does not correct the underlying defect; instead it aims to ease abnormal heart function, relieve symptoms, and bring down dangerously high pressure in the lungs until a more complete repair becomes possible. Advances in definitive surgical repair have reduced how often the procedure is used over the years, but it remains in wide clinical use for infants for whom full corrective surgery is not yet feasible.

FAQs
Why can a pulmonary artery band need further surgery?
Because the right tightness is hard to judge and the band can shift or scar, up to one third of patients need adjustment surgery.
The main difficulty is judging how tight the band should be, because very small changes in the diameter of the pulmonary artery can have large effects on resistance and blood flow. A band can also migrate from its original position and narrow the vessel too much, and calcium deposits and scarring around the band have been reported to inhibit blood flow. Additional operations to adjust band tightness occur in up to one third of patients.
