Cardiac ablation

Catheters positioned in the heart for cardiac ablation

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.

Cardiac ablation usually uses long, flexible tubes (catheters) inserted through a vein or artery in your groin and threaded to your heart to deliver energy in the form of heat or extreme cold to modify the tissues in your heart that cause an arrhythmia.

Cardiac ablation is sometimes done through open-heart surgery, but it’s often done using catheters, making the procedure less invasive and shortening recovery times.

Types
Atrial flutter ablation
Pulmonary vein isolation
SVT ablation
Ventricular tachycardia ablation
Why it’s done
Cardiac is a procedure that’s used to correct heart rhythm problems.

When your heart beats, the electrical impulses that cause it to contract must follow a precise pathway through your heart. Any interruption in these impulses can cause an abnormal heartbeat (arrhythmia), which can sometimes be treated with cardiac.

Ablation isn’t usually your first treatment option. Ablation is a treatment option for people who:

Have tried medications to treat an arrhythmia without success
Have had serious side effects from medications to treat arrhythmias
Have certain types of arrhythmias that respond well to ablation, such as Wolff-Parkinson-White syndrome and supraventricular tachycardia
Have a high risk of complications from their arrhythmias, such as sudden cardiac arrest
