Balloon treatment for chronic blood-clot lung vessel disease
Part of Heart & circulation, Lungs & breathing clinical trials.
This trial tests whether a procedure called balloon pulmonary angioplasty is safe and effective for people with chronic thromboembolic disease in the lungs, especially when surgery isn’t an option. If you have CTEPH, it may help improve lung blood flow and symptoms.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You’ve been diagnosed with CTEPH (chronic blood-clot related lung vessel disease) based on guideline criteria
- Your blood pressure in the lungs is high (or, if not high at rest, you still have activity limits due to this condition)
- Your lung scans/tests show chronic clot-related blockage (such as VQ scan and lung vessel imaging like CT angiogram or MRI)
- You’ve been on blood thinners (anticoagulation) for at least 3 months before this diagnosis
- You are not able to or are not suitable for the surgery called pulmonary endarterectomy
- You can give written consent and you can reliably return for follow-up visits

This study helps doctors update and improve how they understand chronic thromboembolic pulmonary hypertension (CTEPH) in patients in China. It likely involves sharing your medical information (not a new drug) and confirming your diagnosis details to support future research.
This trial is for people with a type of long-term blood clot in the lungs (CTEPH) who have been taking riociguat for at least 12 weeks. It will see what happens when the medication is stopped, focusing on how the right side of the heart is doing.
This study compares balloon pulmonary angioplasty versus pulmonary endarterectomy for people with chronic thromboembolic pulmonary hypertension (high blood pressure in the lungs due to long-lasting blood clots). It may help find which procedure works better for improving symptoms and lung circulation after treatment.
This study builds a registry to learn about people with chronic blood-clot lung disease (CTEPD/CTEPH) and what symptoms and test results look like over time. It may help clinicians better understand the condition and improve future care, since your participation supports data collection rather than a new drug.
This study looks at patterns from specialized lung scan tests to help diagnose chronic thromboembolic pulmonary hypertension (a long-term problem with blood flow in the lungs after blood clots). If your results suggest this condition and you need a procedure to check heart pressure, you may be asked to join so the researchers can improve diagnosis.
This study is a registry that collects information about people with chronic thromboembolic pulmonary hypertension (CTEPH). It helps doctors learn more about how this condition affects patients over time and how it is treated.
