There are many treatments for pulmonary arterial hypertension (PAH). Which treatment or combination of treatments you'll be offered will depend on a number of factors, including what's causing PAH and the severity of your symptoms.
Some people with pulmonary hypertension may need surgery. The three types of surgery currently used are:
pulmonary endarterectomy – an operation to remove old blood clots from the pulmonary arteries in the lungs in people with chronic thromboembolic pulmonary hypertension
balloon pulmonary angioplasty – a new procedure where a tiny balloon is guided into the arteries and inflated for a few seconds to push the blockage aside and restore blood flow to the lung; it may be considered if pulmonary endarterectomy isn't suitable, and has been shown to lower blood pressure in the lung arteries, improve breathing, and increase the ability to exercise
atrial septostomy – a small hole is made in the wall between the left and right atria of the heart using a cardiac catheter, a thin, flexible tube inserted into the heart's chambers or blood vessels; it reduces the pressure in the right side of the heart, so the heart can pump more efficiently and the blood flow to the lungs can be improved
