This trial is studying balloon pulmonary angioplasty (BPA), a minimally invasive procedure that uses a small balloon to open up blood vessels in the lungs that have been blocked by chronic blood clots. Researchers want to understand how well this treatment works, how safe it is, and what kinds of tests can predict which patients will benefit most from it.
Some patients with chronic blood clots in their lungs cannot have traditional surgery to remove the clots. This trial exists to better understand whether this balloon procedure is a safe and effective option for these patients, and to learn which tests can help doctors predict who will do well with the treatment.

You will receive the balloon procedure (BPA) as part of your medical care. Before treatment and then 3 to 12 months after your last procedure session, you'll complete several monitoring visits that include a 6-minute walking test, blood work, heart imaging, heart function tests, and other scans. Researchers will track your progress and compare your health status before and after treatment to see how well the procedure worked for you.
