Catheter ablation is a nonsurgical way to treat heart irregular heartbeats, or arrhythmias, like atrial fibrillation (AFib), atrial flutter, or supraventricular tachycardia (SVT). It destroys the tissue that’s causing your heartbeat to get off course. This creates scar tissue inside your heart. This scar tissue is a good thing.
Atrial fibrillation ablation is a procedure to treat atrial fibrillation. It uses small burns or freezes to cause some scarring on the inside of the heart to help break up the electrical signals that cause irregular heartbeats.

Catheter ablation is a procedure that uses radiofrequency energy (similar to microwave heat) to destroy a small area of heart tissue that is causing rapid and irregular heartbeats. Destroying this tissue helps restore your heart’s regular rhythm.

During the Procedure: WHAT TO EXPECT DURING CATHETER ABLATION. Catheter ablation is performed by an electrophysiologist (EP), a heart doctor who specializes in heart rhythms. During the procedure, you’ll receive fluids and any necessary medication through an intravenous (IV) line inserted in your arm.
Cardiac ablation is a procedure that can correct heart rhythm problems (arrhythmias). Cardiac ablation works by scarring or destroying tissue in your heart that triggers or sustains an abnormal heart rhythm. In some cases, cardiac ablation prevents abnormal electrical signals from entering your heart and, thus, stops the arrhythmia.
Catheter ablation is a procedure used to remove or terminate a faulty electrical pathway from sections of the hearts of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter, supraventricular tachycardias (SVT) and Wolff-Parkinson-White syndrome (WPW syndrome). If not controlled, such arrhythmias increase the risk of ventricular fibrillation and sudden cardiac arrest. The ablation procedure can be classified by energy source: radiofrequency ablation and cryoablation.
Atrial fibrillation (AF or A-fib) is an abnormal heart rhythm characterized by rapid and irregular beating of the atria. Often it starts as brief periods of abnormal beating which become longer and possibly constant over time. Often episodes have no symptoms. Occasionally there may be heart palpitations, fainting, lightheadedness, shortness of breath, or chest pain. The disease is associated with an increased risk of heart failure, dementia, and stroke. It is a type of supraventricular tachycardia. High blood pressure and valvular heart disease are the most common alterable risk factors for AF. Other heart-related risk factors include heart failure, coronary artery disease, cardiomyopathy, and congenital heart disease. In the developing world valvular heart disease often occurs as a result of rheumatic fever. Lung-related risk factors include COPD, obesity, and sleep apnea. Other factors include excess alcohol intake, tobacco smoking, diabetes mellitus, and thyrotoxicosis. However, half of cases are not associated with any of these risks. A diagnosis is made by feeling the pulse and may be confirmed using an electrocardiogram (ECG). A typical ECG in AF shows no P waves and an irregular ventricular rate. AF is often treated with medications to slow the heart rate to a near normal range (known as rate control) or to convert the rhythm to normal sinus rhythm (known as rhythm control). Electrical cardioversion can also be used to convert AF to a normal sinus rhythm and is often used emergently if the person is unstable. Ablation may prevent recurrence in some people. For those at low risk of stroke, no specific treatment is typically required, though aspirin or an anti-clotting medication may occasionally be considered. For those at more than low risk, an anti-clotting medication is typically recommended. Anti-clotting medications include warfarin and direct oral anticoagulants. Most people are at higher risk of stroke. While these medications reduce stroke risk, they increase rates of major bleeding. Atrial fibrillation is the most common serious abnormal heart rhythm. In Europe and North America, , it affects about 2 to 3% of the population. This is an increase from 0.4 to 1% of the population around 2005. In the developing world, about 0.6% of males and 0.4% of females are affected. The percentage of people with AF increases with age with 0.1% under 50 years old, 4% between 60 and 70 years old, and 14% over 80 years old being affected. A-fib and atrial flutter resulted in 193,300 deaths in 2015, up from 29,000 in 1990. The first known report of an irregular pulse was by Jean-Baptiste de Sénac in 1749. This was first documented by ECG in 1909 by Thomas Lewis.
Radiofrequency ablation (RFA) is a medical procedure in which part of the electrical conduction system of the heart, tumor or other dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz). RFA is generally conducted in the outpatient setting, using either local anesthetics or conscious sedation anesthesia. When it is delivered via catheter, it is called radiofrequency catheter ablation. Two important advantages of radio frequency current (over previously used low frequency AC or pulses of DC) are that it does not directly stimulate nerves or heart muscle and therefore can often be used without the need for general anesthetic, and that it is very specific for treating the desired tissue without significant collateral damage. Documented benefits have led to RFA becoming widely used during the 21st century.
