A tiny sensor inside the lung could reveal hidden pressure problems after Life-Saving surgery
NCT ID NCT07758179
First seen Aug 11, 2026 · Last updated Aug 12, 2026 · Updated 1 time
Summary
This study tests whether a small implanted sensor, called CardioMEMS, can continuously track blood pressure in the lung arteries after surgery for chronic thromboembolic pulmonary hypertension (CTEPH). The surgery, called pulmonary endarterectomy, can cure CTEPH, but some patients still have high blood pressure afterward. Currently, doctors check this with occasional invasive tests, which miss changes over time. The study will place the sensor during surgery and monitor pressure remotely to see when it stabilizes and how it relates to recovery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- CardioMEMS™, a small implanted sensor that continuously measures blood pressure in the lung arteries
- What this could lead to
- If successful, this could show that continuous pressure monitoring helps doctors detect and manage residual pulmonary hypertension earlier after surgery, potentially improving recovery and long-term outcomes.
- What could go wrong
- This is a small, early feasibility study, so results may not apply broadly. The sensor stays in permanently and carries a small risk of blood clots or device-related issues, though these are reported to be low.
