WHAT IS HEART ABLATION?
Heart ablation (also called cardiac ablation) is a procedure that can treat abnormally fast heartbeats by selectively ablating, or creating scars, in small areas of heart tissue that your doctor has identified as causing the arrhythmia.
HOW CARDIAC ABLATION WORKS
By permanently scarring abnormal heart tissue, your doctor redirects your heart’s electrical signals so your heart beats normally again.
There are two general types of cardiac ablation: catheter ablation and surgical ablation. During catheter ablation, a doctor threads several catheters—special long, flexible tubes with wires—into your heart to study your arrhythmia and to deliver radio frequency energy to scar the areas of your heart responsible for the abnormal rhythm. In surgical ablation, often done when patients are undergoing other surgical procedures on their hearts, you doctor makes small cuts in your heart tissue, or uses other means, to scar the heart tissue.
