Study of a Heart Procedure for High Blood Pressure in the Lungs

This is a real-world study following patients who have already received percutaneous pulmonary artery denervation (PADN)—a minimally invasive procedure that uses heat or cold to calm overactive nerves in the lung blood vessels. The study will track how well this treatment works for people with pulmonary arterial hypertension (a condition where blood pressure becomes dangerously high in the lungs). Researchers want to understand how the procedure performs outside of controlled clinical trials, in everyday medical practice.

Pulmonary arterial hypertension can be very difficult to treat, and current medications don't work well for everyone. This study exists to gather real-world evidence about whether this newer nerve-calming procedure can help patients breathe easier and improve their quality of life.
