Summary

This study will compare two types of heart-lung machines used during coronary bypass surgery to see how they affect blood flow to the brain. Researchers will measure brain pressure using an eye ultrasound and brain oxygen levels with a forehead sensor in 70 patients. The goal is to find out which machine technique is safer for the brain during 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 could help doctors choose safer heart-lung machine methods to protect the brain during bypass surgery.
What could go wrong: This is a small, early-stage observational study (70 people) that measures markers, not patient outcomes. It may not lead to clear changes in practice.
