maze procedure
Surgical treatment for atrial fibrillation using strategic incisions or ablation lines.
Full Definition
The maze procedure is a surgical technique designed to treat atrial fibrillation by creating a series of strategic incisions or ablation lines in the atrial tissue that redirect electrical impulses along a controlled path to the ventricles, similar to navigating a maze. The procedure eliminates the chaotic electrical activity that characterizes atrial fibrillation. Modern versions often use radiofrequency, cryotherapy, or microwave energy instead of surgical incisions, and the procedure may be performed concomitantly with other cardiac surgeries.
Usage
Usage note: Often preceded by 'Cox' to indicate the specific technique. Capitalize 'Maze' when referring to the Cox-Maze procedure.
