Summary

This study tests a modified Maze procedure done during heart surgery to treat atrial fibrillation, a common heart rhythm problem. About 151 adults with AFib scheduled for heart surgery will receive the procedure, which uses heat or cold to create scar lines in the heart and closes a small pouch to reduce stroke risk. The goal is to see if patients stay in normal rhythm 12 months later, while also tracking safety and quality of life.
