Test using lung scan patterns to diagnose a heart-lung condition
Treatments studied
Part of Heart & circulation, Lungs & breathing clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have symptoms and test results that suggest chronic thromboembolic pulmonary hypertension (CTEPH).
- Your lung scan tests and an ultrasound of your heart (echocardiography) fit the study’s diagnosis standard (per French recommendations).
- You need a right heart catheterization (a procedure to measure pressure inside the right side of your heart).
- Your lung scan must not be normal on the perfusion scan.
- You must be able to give informed consent after learning about the study.
- You must have French social security coverage (affiliated or entitled).

Other trials that look related to this one.
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.
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 tests if a small sensor placed in your lung artery during surgery can safely help doctors watch for remaining high blood pressure after the operation. It may help catch problems earlier, but it is a small exploratory study for people at higher risk of having this issue.
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 trial uses a special lung scan (SPECT-CT) to look for leftover blood clots in people with high blood pressure in the lungs or ongoing shortness of breath after a clot. It may help doctors better understand these conditions.
This study looks at lung tissue from surgery to learn how pulmonary hypertension (high blood pressure in the lungs) develops in people with lung disease. The goal is to find better ways to diagnose and treat this condition.
