surgery in atrial fibrillation

Last reviewed 05/2021

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
