Heart surgery monitoring under the microscope: is the standard test accurate enough?
NCT ID NCT07163052
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study will compare two ways of measuring pressure inside the heart during heart surgery: the gold standard (direct left atrial pressure) and a more common indirect method (pulmonary capillary wedge pressure). Researchers want to see if the indirect method is accurate enough to guide decisions about fluid management and heart support. About 136 adults having elective heart surgery will take part, and the results could improve how doctors monitor patients during and after surgery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this study could confirm that a less invasive pressure measurement is reliable enough for guiding treatment in heart surgery patients.
- What could go wrong
- This is an observational study, not a treatment trial. It may find that the two measurements do not agree well, meaning current practice needs rethinking but no direct patient benefit is guaranteed.
