We anesthetized three patients with refractory atrial fibrillation undergoing the new thoracoscopic mini Maze procedure. An ablation is usually a catheter based procedure and the maze is an open surgical procedure.
When Is A Maze Procedure A Maze Procedure Canadian Journal Of Cardiology
The Cox-maze IV procedure that uses radiofrequency energy for ablation is established as an effective way to eliminate atrial fibrillation.
Mini maze procedure vs catheter ablation. Since there are advantages to both the mini maze procedure and catheter ablation the newer convergent procedures combine the best of the mini maze procedure and catheter ablation in the same operation and offer a lot of promise. Mini-mazes however should not be confused as all that mini Patients are exposed to lengthy periods of anesthesia sequential deflation of the lungs chest wall access painful and dissection of important structures in the chest.

Send thanks to the doctor 90000 US. This technique is performed in collaboration with cardiothoracic surgeons and is used to interrupt the electrical pathways in the upper chambers of the heart converting AF to a normal rhythm. However long term success still remains low.
Catheter ablation of atrial tachyarrhythmias after a Maze procedure. Doctors typically provide answers within 24 hours. Mini-Maze Not Recommended for First Timers.
Catheter ablation is done by an electrophysiologist on the inside of the heart by accessing it through the groin or sometimes arm or neck. This requires 1-2 days in the hospital. Collaborations between electrophysiologists and cardiothoracic surgeons especially at integrated afib centers.
Doctors your own question and get educational text answers its anonymous and free. A single center experience. More recently the Wolf Mini-Maze procedure has been utilized with promising results.
And like catheter ablation does these procedures require hard-won surgical skills honed over many cases. Mini-Maze surgeries usually have significant risks compared with catheter-based electrophysiology procedures such as catheter ablation 13 A study comparing catheter versus surgical ablation found that Mini-Maze surgeries had about a one in four chance of a major adverse event. Hybrid surgical-catheter ablation combines catheter ablation which treats the inside of the heart with the mini-maze procedure which treats.
- A catheter ablation is typically an outpatient procedure less than 24 hours and requires a few days off work and slowly easing back into things over a few weeks. Non-pulmonary vein triggers are often targeted in such redo-catheter ablation procedures. It may be used in patients with chronic persistent AF.
1Department of Cardiovascular Medicine Chiba University Graduate School of Medicine Chiba Japan. Whereas surgical treatments such as the Mini-Maze are generally not a first option Class IIb The exception is special circumstances such as intolerance to anticoagulants. The Mini-Maze ablation procedures are derived from the original Cox-Maze operations developed in the 1980s and early 1990s.
Since there are advantages to both the mini maze procedure and catheter ablation the newer convergent procedures combine the best of the mini maze procedure and catheter ablation in the same operation and offer a lot of promise. 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. The Mini-Maze procedure provides an alternative to conventional catheter ablation for atrial fibrillation AF.
Though this approach remains controversial. Doctors in 147 specialties are here to answer your questions or offer you advice prescriptions and more. This minimally invasive surgical procedure provides isolation and ablation of the bilateral pulmonary vein without thoracotomy or cardiopulmonary bypass which was performed first in the United States in 2003.
- A mini maze is typically 2-3 days in the hospital and a longer recovery. An ablation is usually a catheter based procedure and the maze is an open surgical procedure. Mini maze is done by a cardiac surgeon on the outside of the heart by accessing it through the underarm area or through the ribs.
Redo-catheter ablation is routinely offered for such patients. Compared to the Cox-maze IV procedure the video-assisted Wolf mini-maze procedure is associated with reduced surgical trauma but still requires bilateral thoracotomies and the ablation line connecting. Performed through a standard sternotomy and using the heart-lung bypass machine these operations were designed to surgically interrupt the reentrant electrical pathways found in atrial wall tissue that cause atrial fibrillation and atrial flutter.
In-hospital complications associated with catheter ablation of atrial fibrillation in the United States between 2000 and 2010. In general catheter ablation is recognized in current guidelines as a first option treatment for A-Fib Class IIa. Analysis of 93 801 procedures.
