While no cure has been found for secondary or idiopathic pulmonary hypertension, there are several treatments that can decrease pulmonary arterial pressure and improve your child's symptoms.

For idiopathic PH in particular, treatment is aimed at alleviating and controlling symptoms. This may be done using medication. Only in severe cases is surgery needed.

Secondary pulmonary hypertension

The most common types of treatments used for secondary pulmonary hypertension include:

  • Inhaled oxygen to help raise the levels of oxygen in the bloodstream. This may be particularly helpful while sleeping, when your child may breathe less strongly than when he's awake. Oxygen is given by two small tubes in the very front of the nose ("nasal cannula"), and can help your child even when she is walking about.
  • Inhaled nitric oxide (iNO) to relax pulmonary blood vessels. given just like inhaled oxygen, iNO is typically used in children hospitalized for short-term therapy (usually hours or days) or for testing the pulmonary arteries during heart catheterization.
  • Medications that help to relax pulmonary blood vessels, making it easier for your child's heart to pump blood. These come in several different forms: oral (pill), inhaled, or injected through the skin.
  • Anticoagulants can prevent blood clots in your child's lungs.
  • Diuretics can help your child's kidneys eliminate water.
  • Atrial septostomy may be used in severe cases of pulmonary hypertension if medication fails to control the child's right ventricle from working very hard to pump blood. This surgery is done in the catheterization laboratory. During the procedure, a small hole is created between the upper chambers of your child's heart muscle, redirecting some of the flow of blood past the right ventricle to the left ventricle.
  • A new, experimental form of therapy, called the transvascular Potts procedure is being pioneered at Boston Children's. In this procedure, a small shunt is placed between the pulmonary artery and the aorta (main artery to the body), to increase blood flow to the heart and lower blood pressure.
  • Lung transplantation may be an option for some patients who do not respond to medication.
