Definition
Cardiac ablation is a procedure that can correct heart rhythm problems (arrhythmias). Ablation typically uses catheters — long, flexible tubes inserted through a vein in your groin and threaded to your heart — to correct structural problems in your heart that cause an arrhythmia.
Cardiac ablation works by scarring or destroying tissue in your heart that triggers an abnormal heart rhythm. In some cases, ablation prevents abnormal electrical signals from traveling through your heart and thus stops the 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.
