Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at whether using multiple brain monitoring tools together can help predict strokes in people having heart surgery. About 369 high-risk patients will be watched during surgery to see if the monitoring can give early warning. The goal is to find better ways to protect the brain and reduce stroke risk.
