The Maze procedure: surgical therapy for refractory atrial fibrillation
Key result
Maze procedure restores sinus rhythm without antiarrhythmic drugs in one patient with refractory AF.
- n=1
Why the study?
Although atrial fibrillation is well tolerated by most patients, in some patients the consequences may be severe, prompting the need for effective surgical therapy.
Does the Maze procedure restore sinus rhythm and improve symptoms in patients with refractory atrial fibrillation?
Population

Structured PICO
Does the Maze procedure restore sinus rhythm and improve symptoms in patients with refractory atrial fibrillation?
P
Population
One patient with refractory atrial fibrillation undergoing the Maze procedure.
I
Intervention
Maze procedure (open-heart operation creating a maze of incisions in the atrial myocardium)
O
Outcome
Restoration of sinus rhythm and atrial systole
The Maze procedure represents a novel surgical intervention for refractory atrial fibrillation aimed at restoring sinus rhythm and atrial transport function.
Cite This Study
McCarthy et al. (1993) conducted a case report in Refractory atrial fibrillation (n=1). Maze procedure was evaluated. The Maze procedure was described in a single patient with refractory atrial fibrillation as a surgical therapy to restore sinus rhythm and eliminate the need for antiarrhythmic drugs.
