Chronic Thromboembolic Pulmonary Hypertension (CTEPH)

What Is CTEPH?

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare and potentially fatal form of elevated blood pressure in the lungs (known as pulmonary hypertension). It occurs when blood vessels in the lung have been blocked by a clot for a long time.

The clots that trigger CTEPH often start elsewhere, such as in the leg, and travel through the veins and heart to become lodged in the lung. This type of clot in the lung is called a pulmonary embolism (PE). Over half of patients with CTEPH are not aware they have had a PE.

While most pulmonary embolisms can be easily dissolved with blood thinners, those that cannot are considered chronic. This accounts for about 3%-5% of all PE cases.

In CTEPH, the clot extends within the artery, clings to the artery wall and resembles scar tissue. This increases pulmonary pressure, reduces blood flow into the lungs and can trigger narrowing of other blood vessels throughout the lung.


When symptoms of CTEPH start to develop, they can cause:

  • Shortness of breath
  • Tiredness
  • Chest pain
  • Racing heartbeat

As the condition worsens, it may ultimately limit all physical activity.

Candidates for PTE Surgery

When left untreated, patients with CTEPH have a life expectancy of between 1 and 3 years. Fortunately, a procedure called pulmonary thromboendarterectomy (PTE) can significantly improve quality of life for patients who are candidates for surgery. Patients who aren’t medically eligible for PTE may still benefit from medication or balloon angioplasty.
