Can a CT scan predict heart procedure success?

This study looks at whether a special CT scan can measure scarring in the heart muscle of people with atrial fibrillation (an irregular heartbeat). Researchers want to see if more scarring leads to worse outcomes after a common treatment called ablation. About 100 adults scheduled for ablation will get an extra CT scan, and their recovery will be tracked for 90 days. The goal is to find a simple way to predict who might need more aggressive treatment.
