How long does the maze procedure last?

How long does the maze procedure last?

Procedure Length The operation usually takes two to four hours. You will be connected to a heart-lung machine to keep your body functional during the operation. We will make an incision (cut) down the middle of your chest or right side of chest to access your heart.

Who is a candidate for Mini-Maze procedure?

Based on input from many surgeons, most afib patients who undergo minimally invasive surgical ablation procedures meet the following criteria: Have a confirmed diagnosis of atrial fibrillation. Are between the ages of 18 and 80 — although some patients over the age of 80 are also good candidates.

What is a mini-maze procedure?

During the Mini-Maze procedure, surgeons at Methodist use a special instrument to destroy a small amount of tissue in the heart. The destroyed tissue effectively blocks the abnormal electrical impulses and stops atrial fibrillation from reaching the main part of the atrium.

Is the mini maze better than ablation?

Summary: A randomized trial showed that minimally invasive (mini maze) surgical ablation was more effective, but with more complications, than catheter ablation at treating atrial fibrillation patients who had failed a previous catheter ablation or had an enlarged left atrium.

What is a mini maze procedure?

Can an ablation cause congestive heart failure?

All patients had complete recovery with supportive therapy within 3 days of the onset of symptoms. Conclusions: In this single-center experience, CHF after extensive ablation for AF was a well-recognized complication with a relatively high incidence of 2.5%.

Does ablation shorten life?

Long-term survival is similar for patients with atrial fibrillation, whether they receive ablation or drug therapy. Control of the ventricular rate by ablation of the atrioventricular node and permanent pacing does not adversely affect long-term survival.

What is the death rate of catheter ablation?

The early mortality rate after CA of AF is 0.46%, with approximately 50% of deaths occurring during rehospitalizations within the first 30 days of the index hospitalization.

What are the risks of maze procedure?

While Maze procedure, especially when performed using ablation, is very safe—studies found it has a 90% success rate, with 99% post-operative patients seeing no recurrence of stroke—there are some risks to this surgery. 1  These include: 4  Maze procedure is primarily a treatment for AFib, a conditioned characterized by: 2

What is a maze procedure for heart problems?

A maze procedure involves making a series of tiny cuts in the heart muscle with a laser. As the cuts heal, your body makes scar tissue that blocks the disorganized electrical signal and irregular heart rhythm. This allows your heart to beat normally. A maze procedure is major surgery that has risks and potential complications.

Mini-Maze Procedure—Minimally Invasive Surgery. Definition. The Mini-Maze procedure is a surgical procedure of the heart. A pattern of scars are made in the upper chambers of the heart which may look like a maze.

Is mini maze ablation more effective than catheter ablation?

January 9, 2012 — According to a recent study, minimally invasive surgical ablation, often called the mini maze procedure, was more effective than catheter ablation in treating atrial fibrillation patients who had previously failed a catheter ablation or who had an enlarged left atrium. Dr.
