Atrial Septostomy
Atrial septostomy is a surgical procedure that creates a communication between the right and left atria. It relieves pressure on the right side of the heart, but at the cost of lower oxygen levels in blood (hypoxia). It is best performed in experienced centers. Lung transplantation cures pulmonary arterial hypertension, but leaves the patient with the complications of transplantation, and a survival of about 5 years.

Pulmonary thromboendarterectomy
Pulmonary thromboendarterectomy (PTE) is a surgical procedure that is used for chronic thromboembolic pulmonary hypertension. It is the surgical removal of an organized thrombus (clot) along with the lining of the pulmonary artery; it is a large and very difficult procedure that is currently performed in a few select centers. Case series show remarkable success in most patients.

Treatment for hypoxic and miscellaneous varieties of pulmonary hypertension have not been established. However, studies of several agents are currently enrolling patients. Many physicians will treat these diseases with the same medications as for PAH, until better options become available.
