Your doctor may have you take a diuretic at home for several weeks following surgery. This type is most common when you’re having open-heart surgery for another problem, like valve surgery or a bypass. This technique takes less time than heat ablation and may have similar risks and complications. The signal then travels through the atria to the atrioventricular (AV) node and then passes into the ventricles, causing them to contract and pump out blood. This causes scarring that disrupts the faulty electrical signals and restores normal heart rhythms.

The catheters have electrodes at the tips that can be used to send electrical impulses to your heart and record your heart's electrical activity. Ruaengsri C, et al. Cryoballoon ablation of pulmonary veins for paroxysmal atrial fibrillation: First results of the North American Arctic Front (STOP AF) Pivotal Trial. Planning the Safety of Atrial Fibrillation Ablation Registry Initiative (SAFARI) as a collaborative pan-stakeholder critical path registry model: A cardiac safety research consortium "incubator" think tank. An electrocardiogram and chest X-ray lets your doctor see the current condition of your heart. In a normal heart, the upper chambers (atria) beat in a synchronized way with the lower chambers (ventricles) to keep blood pumping through your body. AV node ablation may be a good option for you if your atrial fibrillation doesn't get better with other treatments. The use of extreme cold to cause scarring (cryoablation) is a newer technique. If you experience any type of severe pain or shortness of breath, let your doctor know. How Long Does Coronavirus Live On Surfaces?

In this procedure, your doctor threads one or more long, thin tubes (catheters) through blood vessels to your heart.

In an open-heart maze procedure: Mini maze:  Most people with AFib don’t need open-heart surgery. (2012).

With atrioventricular (AV) node ablation, your doctor uses catheters to create scarring in an area of your heart called the AV node. EnglishEspañol (Spanish)Hmoob (Hmong)繁體中文 (Chinese)Deutsch (German)العربية (Arabic)Русский (Russian)한국어 (Korean)Tiếng Việt (Vietnamese)Deitsch (Pennsylvania Dutch)ພາສາລາວ (Lao)Français (French)Polski (Polish)हिंदी (Hindi)Shqip (Albanian)Tagalog (Tagalog – Filipino). Accessed Dec. 26, 2019. Many people with atrial fibrillation take medicines to help control their heart rate or their heart rhythm. During an arrhythmia, your heart’s beating speed and pattern is altered.

If you've had problems with general anesthesia, tell your doctor before the day of the surgery. January CT, et al. Maze is a surgical procedure used to treat atrial fibrillation. You may feel more tired than usual, but most people are back to normal within 6 months. It can also be called a surgical ablation.

The scarring prevents the chaotic electrical signals that cause atrial fibrillation, by guiding the signals along an organized path, or "maze," to the lower ventricles of the heart.

Your ventricles respond to these extra, chaotic signals by beating faster than normal. It may be done through small cuts in the chest. In a normal heart rhythm, a tiny cluster of cells at the sinus node sends out an electrical signal.

The scar tissue prevents the atria from sending faulty electrical impulses to the ventricles.

Radio waves that generate heat run through a catheter into your atria to destroy the faulty tissues.

2012;9:632. The scar tissue, which does not conduct electrical activity, blocks the abnormal electrical signals causing the arrhythmia. The maze procedure is a surgical treatment for atrial fibrillation. It is used to control the irregular heartbeat and restore the normal rhythm of the heart. Heart Rhythm. ", University of Washington School of Medicine and Public Health: "Robotic Maze Procedure for Atrial Fibrillation. Circulation: Arrhythmia and Electrophysiology.

Your doctor will put a video camera or tiny robot into your chest. This is a highly effective procedure that works by creating scar tissue that, in turn, prevents irregular electrical signals from traveling through the heart. See our safe care and visitor guidelines, plus trusted coronavirus information. After your sedative takes effect, your doctor or another specialist will numb a small area near a vein on your groin, neck or shoulder. Author: Healthwise Staff Medical Review: Rakesh K.

Gregory Thompson, MD - Internal Medicine & Adam Husney, MD - Family Medicine & John M. Miller, MD, FACC - Cardiology, Electrophysiology. Most people spend the first 2 or 3 days after surgery in an intensive care unit (ICU) where they can be closely watched.

Bleeding or infection at the surgical site or where your catheter was inserted, Damage to your heart's electrical system, which could worsen your arrhythmia and require a pacemaker to correct, Blood clots in the legs or lungs (venous thromboembolism), Narrowing of the veins that carry blood between your lungs and heart (pulmonary vein stenosis). January CT, et al. Learn effective ways to relieve stress and anxiety with these 16 simple tips. Mechanisms of cardiac arrhythmias. Badwar V, et al. If the scar tissue is electrically inert, how might this procedure prevent atrial fibrillation?

The cryomaze procedure uses extreme cold temperatures instead of heat to kill the area of your heart that causes the fibrillation episodes. Al-Khatib SM, et al. Barbara Woodward Lips Patient Education Center.

2016;171:48. See how much you know about abnormal heart rhythm. In this operation, the surgeon makes tiny burns or cuts in the upper chambers of the heart, causing scar tissue.

If your atrial fibrillation returns, you may need another catheter ablation or other treatment. It can stop atrial fibrillation in about 9 people out of 10. footnote 3You may need to take heart rhythm medicine (antiarrhythmics) after the procedure. 2012 HRS/EHRA/ECAS expert consensus statement on catheter and surgical ablation of atrial fibrillation: Recommendations for patient selection, procedural techniques, patient management and follow-up, definitions, endpoints, and research trial design. Healthwise, Incorporated, disclaims any warranty or liability for your use of this information. Ablation of the pulmonary vein for atrial fibrillation. Because scar tissue doesn't carry electricity, the maze interferes with stray electrical impulses that cause atrial fibrillation. The maze procedure is a surgical treatment for atrial fibrillation. Rarely, it's the first choice of treatment for atrial fibrillation.

Each “freeze” takes a minute or two to complete. (2017). You might hear it called Cox maze IV.

In: Braunwald's Heart Disease: A Textbook of Cardiovascular Medicine. As in any operation, your doctor will let you know what you need to do in advance.
