Surgical Procedures for Atrial Fibrillation
If you have severe atrial fibrillation and have not responded to other treatments, the experts at the UPMC Center for Atrial Fibrillation may recommend surgery.
Surgery is often recommended either when other less invasive therapies have been unable to effectively treat atrial fibrillation or when structural changes of the heart exist such as enlarged heart chambers or the presence of a leaking valve, making surgery a more favorable option for long term outcome.
Open MAZE Surgical Procedure
The MAZE procedure is the gold standard open surgical approach to treat atrial fibrillation.
In the MAZE procedure, our expert surgeons use tiny incisions in the heart to create a maze-like pattern of scars in the atria. These scars block the transmission of erratic electrical impulses.
Our surgeons are known for their expertise in the MAZE procedure. Our research and practice have helped evolve this form of therapy for atrial fibrillation.
Minimally Invasive MAZE Surgery
For selected patients, surgeons perform the MAZE procedure using a minimally invasive approach that does not involve opening the breast bone.
An important benefit of this surgery is that it offers the exclusion of the main region of the heart that has been responsible for stroke in atrial fibrillation — the left atrial appendage (appendix of the heart). This may allow patients to be safely taken off of long term Warfarin (Coumadin®) following the MAZE procedure.
Isolated Left Atrial Appendage Ligation
For selected patients who may not be a candidate for other therapies, such as the MAZE procedure, yet medically cannot take anticoagulants such as Warfarin, surgeons perform a minimally invasive approach to close off or ligate the left atrial appendage (or the appendix of the heart).
