Most people do well afterward. Your doctor can help you decide whether the possible benefits of ablation outweigh these risks:. If problems happen during the procedure, your doctor is prepared to fix them right away. In studies and a worldwide survey, serious problems happened in about 4 out people. Rare problems include cardiac tamponade and stroke.
They happen in about 1 out of people. Another serious problem affects the pulmonary vein and happens in about 1 to 6 people out of people. Death from the procedure is very rare. It happens to about 1 out of 1, people. Problems after the procedure can be minor such as mild pain or serious such as bleeding.
Your doctor will check you closely after the procedure. He or she can fix most of these problems. The most common problems are related to the catheter that was inserted in a vein. Most of these vein problems aren't serious. They include minor pain, bleeding, and bruising. Vein problems happen in 0 to 13 people out of In a worldwide survey, serious vein problems happened in 1 out every people. Serious problems aren't common. These problems include stroke and new heart rhythm problems.
A rare problem is a life-threatening problem with the esophagus atrio-esophageal fistula that happens to about 1 out of 1, people. Ablation isn't a choice for some people, including those who:.

Treatment Overview Catheter ablation is a minimally invasive procedure to treat atrial fibrillation. AV node ablation AV node ablation is a slightly different type of ablation procedure for atrial fibrillation. Why It Is Done Ablation is done to stop atrial fibrillation from happening and relieve symptoms. These things include: footnote 3 , footnote 4 What treatment you want to try. What type of atrial fibrillation you have paroxysmal or persistent. How bad your symptoms are.
If you have a problem with the structure of your heart. If you have tried heart rhythm medicines already. Your symptoms may not have gone away or you had side effects that are hard to live with. How Well It Works Catheter ablation can stop atrial fibrillation from happening and can relieve symptoms. Paroxysmal atrial fibrillation Research shows that ablation helps more than 70 to 80 out of people. In a worldwide survey, ablation helped 84 out of every people. In a worldwide survey, ablation helped about 65 out of every people.
Risks Catheter ablation is considered safe. Your doctor can help you decide whether the possible benefits of ablation outweigh these risks: Problems during the procedure If problems happen during the procedure, your doctor is prepared to fix them right away.
Catheter Ablation of Paroxysmal Atrial Fibrillation Originating from Non-pulmonary Vein Areas
There are two commonly used catheter based techniques to achieve pulmonary vein isolation. A number of techniques have been developed since the initial open chest procedures for atrial fibrillation devised by Dr. This technique involved creating a myriad of scars or lesions throughout the left atrium to prevent fibrillatory conduction.
The original "cut and sew" approaches have been supplanted with surgical ablation tools which may use radiofrequency, or cryothermal, energy sources to create scar. Several minimally invasive techniques have been devised as stand-alone procedures. Isolation of the pulmonary veins is considered the hallmark of atrial fibrillation ablation, and is the first line treatment for atrial fibrillation based on more than two decades of research and experience.
As we gain better understanding of atrial fibrillation, newer "triggers" of atrial fibrillation have been targeted for ablation.

In some patients, the chances for restoration of normal sinus rhythm with either catheter or surgical methods are felt to be very low. This may be due to the long standing presence of atrial fibrillation, severe other medical problems, or prior failed ablations. RF ablation of the AV node and pacemaker implantation allows regularization of the heart rate the rapid irregular impulses of atrial fibrillation are no longer transmitted to the lower chambers or ventricles of the heart but results in pacemaker dependence.
Catheter ablation for supraventricular tachycardia is usually accomplished utilizing radiofrequency energy. In a small number of cases, treatment may require using cryo-energy due to the proximity of the ablation site to critical structures of the normal electrical conduction system.
Ventricular tachycardia usually presents in the structurally abnormal heart.
RF ablation has been widely utilized to treat ventricular tachycardia. In addition, there are individuals with a structurally normal heart that present with ventricular tachycardia.

These arrhythmias are very amenable to treatment with RF ablation. Breadcrumb Home. Types of Ablations. Atrial fibrillation AF is the most common abnormal heart rhythm arrhythmia affecting the population which decreases quality of life and significantly increases health care costs. In patients with paroxysmal AF, a minimally invasive procedure called radiofrequency catheter ablation RFA is the standard of care leading to excellent control.
This is associated with improved quality of life and decreased health care burden.
