Summary

This study looked at 86 people with severe aortic valve stenosis who had valve replacement surgery. Researchers used special MRI scans to measure scarring in the heart muscle before and one year after surgery. The goal was to see if the scarring improves and whether MRI could help doctors choose the best time for surgery. This was an observational study, not a treatment trial.
