Atrial Fibrillation Ablation Knows

Atrial fibrillation (atrial fibrillation/AF) is a type of heart arrhythmia. Arrhythmia heart rhythm irregularity is. AF is caused by chaotic electrical impulses originating from the right side of the heart, called the right atrium. An electrical signal that does not fit may cause atrial fibrillation, or be contracting, fast and irregular. During the episode of AF, the heart may beat too fast, or the pattern can not guess.

The definition of "ablation"

The term "ablation" is derived from the verb "ablate United Kingdom language", which means "to remove or destroy". In AF ablation refers to treatment options if medications are not able to control irregular electrical activity in the heart. Ablation is a surgical procedure that punctures the heart network area is very small. The scratched area is the source of the electrical impulses that cause the irregular AF. When living tissue is damaged or destroyed, the network is no longer capable of producing electrical signals wrong resulting in arrhythmias.

A number of the terms used for the procedure, all refer to the same type of treatment:
  • Atrial fibrillation ablation
  • Kateteer ablation
  • Ablation of lung blood vessels
  • Radio-frequency ablation

Preparation of the ablation catheter

Atrial fibrillation ablation is done in the hospital. You will follow the special instructions prior to the procedure, including:
  • Blood work to make sure you are healthy enough for surgery
  • Blood-thinning drugs for a month before surgery to prevent clotting of blood
  • A CT scan or MRI to examine blood vessels used in the procedure
  • Fasting after midnight the day before the ablation
Talk to your doctor about any other medications or dietary supplements that you drink. You may need to stop taking the medication while before ablation as a precaution.

During the procedure for ablation

Catheter ablation is performed under local anesthetic influences, meaning you stay awake and aware, but do not feel pain. After giving you a dope and a local anesthetic, the doctor will insert a catheter — a thin and flexible hose — into a blood vessel in the groin. Sometimes the blood vessels in the neck are used than in the crotch. Using a special x-ray called fluoroscopy to see the location of the placement of the catheter, doctors would remove a catheter leading to the heart.

When the catheter is in place, the doctor will send radio waves through the hose. The tip of the catheter is fitted with a device that heats up from radio frequency. The damaged heart tissue heats instantly destroy it. Ablation is generally taken a few hours.

Ablation with minimum invasion

Ablation procedures with minimum invasion later called "Mini-Maze" may be a treatment effective for atrial fibrillation.

Operations with minimum invasion using a smaller incision and generally does not take a long time as conventional procedures. Mini-ablation Maze requires between 3 and 4 hours. The operation is done with a small incision in the side of the body, below the armpit. The incision should be large enough so that the camera and the catheter can enter. Catheter ablation for standard radio frequency, turn off the network fibrillation that caused AF.


Relatively fast recovery with one type of ablation for atrial fibrillation. You may stay in the hospital for 1 or 2 days so that the medical officer may oversee the activity of your heart. Symptoms of atrial fibrillation often relapse during the first few weeks after surgery. This is a normal part of the recovery process. Blood-thinning drug help prevents problems such as blood clotting. You might as well be drinking an arrhythmia to control irregular electrical activity. Most likely you can have activity as before in a few weeks.


Although the ablation catheter is safe and effective, any type of operation carries risks. Blood clotting, heart impaled accidentally, and stroke is complications that may occur. According to the journal Circulation, this condition affects only 1-2% of the population. Damage to the esophagus is also a risk because the left atrium of the heart is behind the esophagus. Stenosis of the arteries of the lung is a side effect of other ablation. Narrowing of the blood vessels is capable of resulting in a blood clot and other problems associated with the blockage of blood vessels.

The prospect of

The atrial fibrillation ablation success rate varies greatly, depending on the type of AF that you experience. Effective ablation on 30-90% of patients AF. People experiencing episodes of arrhythmia are scarce and intermittent but doesn't have other heart problems more quickly recover. Other patients may experience partial recovery with symptoms that are reduced but not entirely gone.
