Patient ReportsWhat is Chronic Thromboembolic Pulmonary Hypertension?
Written by Medicover Team and Medically Reviewed by Dr Bhima Shankar , Pulmonologists
Table of Contents
Chronic Thromboembolic Pulmonary Hypertension (CTEPH) is a rare but serious form of pulmonary hypertension caused by persistent blood clots that block the pulmonary arteries. These chronic blockages increase pressure in the pulmonary circulation, placing excessive strain on the right side of the heart. Without timely diagnosis and treatment, CTEPH can lead to right heart failure, reduced exercise capacity, and life-threatening complications.
What are the Symptoms of Chronic Thromboembolic Pulmonary Hypertension?
The symptoms of Chronic Thromboembolic Pulmonary Hypertension are often nonspecific and may resemble those of other heart and lung conditions. They usually worsen gradually over time.
- Shortness of breath, especially during physical activity.
- Fatigue and weakness.
- Dizziness or fainting (syncope).
- Chest pain or chest discomfort.
- Swelling in the ankles, feet, or legs.
- Heart palpitations.
If left untreated, these symptoms may progressively worsen, significantly affecting daily activities and quality of life.
What are the Causes of Chronic Thromboembolic Pulmonary Hypertension?
Chronic Thromboembolic Pulmonary Hypertension develops when blood clots remain in the pulmonary arteries instead of dissolving completely. Over time, these clots become organized scar tissue that narrows or blocks the pulmonary arteries, increasing pressure within the lungs.
- Chronic obstruction of the pulmonary arteries by persistent blood clots.
- Previous pulmonary embolism.
- Poor resolution of blood clots.
- Connective tissue diseases.
- Congenital heart defects.
- Chronic lung diseases.
- Inherited or acquired blood clotting disorders.
When to See a Doctor for Chronic Thromboembolic Pulmonary Hypertension?
If you experience persistent shortness of breath, fatigue, chest pain, dizziness, or swelling in the legs after a pulmonary embolism or without a known cause, consult a Pulmonologist. Early diagnosis and treatment can help improve lung function, reduce strain on the heart, and prevent disease progression.
- If you have persistent or worsening shortness of breath during daily activities or exercise.
- If you experience ongoing fatigue, weakness, or reduced ability to perform routine tasks.
- If you develop chest pain, chest tightness, or discomfort, especially during physical activity.
- If you notice dizziness, lightheadedness, fainting (syncope), or episodes of near-fainting.
- If you have swelling in your ankles, legs, or abdomen, which may indicate right-sided heart strain.
- If you have a history of pulmonary embolism and continue to experience breathing difficulties despite treatment.
- If you experience coughing up blood (hemoptysis), severe chest pain, or sudden worsening of breathing, seek immediate emergency medical attention.
- If your symptoms persist or worsen, consult a Pulmonologist for a comprehensive evaluation, pulmonary function assessment, imaging studies, diagnosis, and a personalized treatment plan.

How is Chronic Thromboembolic Pulmonary Hypertension Diagnosed?
Medical History and Physical Examination
Diagnosis begins with a detailed review of symptoms, medical history, previous pulmonary embolism, and a physical examination to identify signs of pulmonary hypertension.
Imaging Studies
Imaging tests are essential for identifying chronic blockages in the pulmonary arteries and assessing blood flow to the lungs.
- Ventilation-Perfusion (V/Q) Scan.
- Computed Tomography Pulmonary Angiography (CTPA).
- Magnetic Resonance Imaging (MRI).
- Pulmonary Angiography when required.
Hemodynamic Assessment
Right heart catheterization is the gold standard for confirming pulmonary hypertension and measuring pulmonary artery pressures to determine disease severity.
How is Chronic Thromboembolic Pulmonary Hypertension Treated?
Treatment focuses on restoring blood flow, lowering pulmonary artery pressure, improving symptoms, and preventing disease progression.
Medical Therapy
Medications help prevent further clot formation and reduce pulmonary artery pressure.
- Anticoagulants (blood thinners).
- Endothelin receptor antagonists.
- Phosphodiesterase-5 inhibitors.
- Other pulmonary vasodilator therapies as indicated.
Pulmonary Thromboendarterectomy (PTE)
Pulmonary thromboendarterectomy is the preferred surgical treatment for eligible patients. It removes chronic clots from the pulmonary arteries and can significantly improve symptoms and survival.
Balloon Pulmonary Angioplasty
Balloon pulmonary angioplasty is a minimally invasive procedure that widens narrowed pulmonary arteries in patients who are not suitable candidates for surgery or who continue to have pulmonary hypertension after surgery.
Supportive Care and Lifestyle Modifications
Supportive measures help improve quality of life and overall cardiovascular health.
- Regular physical activity under medical supervision.
- Heart-healthy, balanced diet.
- Smoking cessation.
- Routine follow-up with a Pulmonologist.
- Monitoring for disease progression and treatment response.
Your health is everything - prioritize your well-being today.

Frequently Asked Questions
1. What are the symptoms of chronic thromboembolic pulmonary hypertension?
Symptoms may include shortness of breath, fatigue, and chest pain, indicating a serious condition requiring evaluation.
2. What causes chronic thromboembolic pulmonary hypertension?
CTEPH results from unresolved blood clots in the pulmonary arteries, leading to increased blood pressure and impaired lung function.
3. How is chronic thromboembolic pulmonary hypertension diagnosed?
Diagnosis typically involves echocardiography, ventilation-perfusion scans, and pulmonary angiography to assess blood flow and pressure in the lungs.
4. What treatment options are available for chronic thromboembolic pulmonary hypertension?
Treatment may include pulmonary thromboendarterectomy, medications, and anticoagulation therapy to improve symptoms and outcomes.
5. What is the role of surgery in chronic thromboembolic pulmonary hypertension?
Surgery, specifically pulmonary thromboendarterectomy, can be curative in select patients with significant obstruction from chronic clots.
