Testing balloon treatment effects on lung blood-vessel surface area

This study tests personalized blood thinner treatments for people with blood clots in their lungs. It looks for patients who are older, have kidney problems, or have cancer, to see if adjusting the treatment helps them more.

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 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 trial tests whether balloon angioplasty can improve breathing and exercise ability in people who still have symptoms and blood flow problems 3 months or more after a pulmonary embolism. It is for those who have completed a pulmonary rehabilitation program.

This study looks at how a minimally invasive procedure called balloon pulmonary angioplasty (BPA) helps patients with chronic blood clots in the lungs improve their heart function and overall recovery. Researchers will measure blood flow patterns in your arteries before and after the procedure to understand how well your heart recovers.

This trial studies how well a treadmill/breathing exercise test can measure health outcomes in people with certain types of pulmonary hypertension. It may help your care team judge your status and track changes over time.
