Overview
A surgical option for some patients with atrial fibrillation is the maze procedure. In this procedure, a series of incisions in a cross like pattern are made on the atria, which blocks the abnormal atrial circuits, hence eliminating the atrial fibrillation. A number of improvements have been made to this surgical procedure since it was first invented.
Indications for Catheter and Surgical Ablation
Ablation of atrial fibrillation is recommended when the primary indication is the presence of symptomatic AF, which is refractory or intolerant to at least one class I or III antiarrhythmic medication. The indications are stratified as class I, class IIa, class IIb, and class III indications.[1]
Class I Indications
In symptomatic paroxysmal AF patients who are either refractory or intolerant to at least one class I or III antiarrhythmic medication, catheter ablation is recommended.
Class IIa Indications
- In symptomatic persistent AF patients who are either refractory or intolerant to at least one class I or III antiarrhythmic medication, catheter ablation is reasonable.
- In symptomatic paroxysmal AF patients, prior to initiation of antiarrhythmic drug therapy with either class I or III antiarrhythmic agent, catheter ablation is reasonable.
- In patients who are undergoing surgery for other indications with symptomatic paroxysmal AF, refractory or intolerant to at least one class I or III antiarrhythmic medication, surgical ablation is reasonable.
- In patients who are undergoing surgery for other indications with symptomatic persistent AF, refractory or intolerant to at least one class I or III antiarrhythmic medication, surgical ablation is reasonable.
- In patients who are undergoing surgery for other indications with symptomatic longstanding persistent AF, refractory or intolerant to at least one class I or III antiarrhythmic medication, surgical ablation is reasonable.
- In patients who are undergoing surgery for other indications with symptomatic paroxysmal AF prior to initiation of antiarrhythmic drug therapy with either class I or III antiarrhythmic agent, surgical ablation is reasonable.
- In patients who are undergoing surgery for other indications with symptomatic persistent AF prior to initiation of antiarrhythmic drug therapy with either class I or III antiarrhythmic agent, surgical ablation is reasonable.
Class IIb Indications
- In symptomatic longstanding persistent AF patients who are either refractory or intolerant to at least one class I or III antiarrhythmic medication, catheter ablation may be considered.
- In patients with symptomatic persistent AF prior to initiation of antiarrhythmic drug therapy with a class I or III antiarrhythmic medication, catheter ablation may be considered.
- In patients with symptomatic longstanding persistent AF prior to initiation of antiarrhythmic drug therapy with a class I or III antiarrhythmic medication, catheter ablation may be considered.
- In patients who are undergoing surgery for other indications with symptomatic longstanding persistent AF prior to initiation of antiarrhythmic drug therapy with a class I or III antiarrhythmic agent, surgical ablation may be considered.
- In symptomatic paroxysmal AF patients who are either refractory or intolerant to at least one class I or III antiarrhythmic medication, stand alone surgical ablation may be considered if they have not failed catheter ablation but prefer a surgical approach.
- In symptomatic paroxysmal AF patients who are either refractory or intolerant to at least one class I or III antiarrhythmic medication, stand alone surgical ablation may be considered if they have failed one or more attempts at catheter ablation.
- In symptomatic persistent AF patients who are either refractory or intolerant to at least one class I or III antiarrhythmic medication, stand alone surgical ablation may be considered if they have not failed catheter ablation but prefer a surgical approach.
- In symptomatic persistent AF patients who are either refractory or intolerant to at least one class I or III antiarrhythmic medication, stand alone surgical ablation may be considered if they have failed one or more attempts at catheter ablation.
- In symptomatic longstanding persistent AF patients who are either refractory or intolerant to at least one class I or III antiarrhythmic medication, stand alone surgical ablation may be considered if they have not failed catheter ablation but prefer a surgical approach.
- In symptomatic longstanding persistent AF patients who are either refractory or intolerant to at least one class I or III antiarrhythmic medication, stand alone surgical ablation may be considered if they have failed one or more attempts at catheter ablation.
Class III Indications
In symptomatic paroxysmal or persistent or longstanding persistent AF patients, prior to initiation of antiarrhythmic drug therapy with a class I or III antiarrhythmic agent, stand alone surgical ablation is not recommended.
Surgery
Maze Procedure
James Cox, MD, and associates developed the Cox maze procedure, an open-heart surgical procedure intended to eliminate atrial fibrillation, and performed the first one in 1987. Maze refers to the series of incisions made in the atria, which are arranged in a maze-like pattern. The intention was to eliminate AF by using incisional scars to block abnormal electrical circuits (atrial macro reentry) that AF requires. This procedure required an extensive series of endocardial (from the inside of the heart) incisions through both atria, a median sternotomy (vertical incision through the breastbone) and cardiopulmonary bypass (heart-lung machine). A series of improvements were made, culminating in 1992 in the Cox maze III procedure, which is now considered to be the gold standard for effective surgical cure of AF. The Cox maze III is sometimes referred to as the traditional maze, the cut and sew maze, or simply the maze.[2]
Minimaze surgery is minimally invasive cardiac surgery similarly intended to cure atrial fibrillation. The minimaze procedure refers to mini versions of the original maze procedure. These procedures are less invasive than the Cox maze procedure and do not require a median sternotomy (vertical incision in the breastbone) or cardiopulmonary bypass (heart-lung machine). These procedures use microwave, radiofrequency, or acoustic energy to ablate atrial tissue near the pulmonary veins.
