Chronic Thromboembolic Pulmonary Hypertension (CTEPH)

Chronic thromboembolic pulmonary hypertension (CTEPH) is a form of pulmonary hypertension, or high blood pressure, affecting the lungs. It is caused by blood clots.

Learn About CTEPH

In some patients, pulmonary embolism, or blood clots, in arteries such as the lungs can form scar-like tissue which can block or narrow the arteries, leading to a form of pulmonary hypertension called chronic thromboembolic pulmonary hypertension (CTEPH).

CTEPH Symptoms, Causes and Risk Factors

Symptoms can start very mild and progress with time, and are similar to other diseases. This makes CTEPH difficult to diagnose, especially in its early stages.

The diagnosis of CTEPH involves using a lung ventilation-perfusion scan and an echocardiogram (an ultrasound of the heart) to look for the disease. For most patients, treatment involves surgery to remove the clots.
