Surgery in atrial fibrillation

Last reviewed dd mmm yyyy. Last edited dd mmm yyyy

Surgical treatment of atrial fibrillation is rare.

Incisions in the myocardium of the atria permit channeling of the electrical depolarisation:

  • in the corridor procedure a single channel of myocardium is created which connects the sinoatrial node and the atrioventricular node
  • in the maze procedure a maze of conducting strips of myocardium are created which permit channeling of depolarisation across the atria; this procedure maintains co-ordinated atrial and ventricular activity
