How serious is ablation surgery?

In general, cardiac (heart) catheter ablation is a minimally invasive procedure and risks and complications are rare. Catheter ablation may require an overnight stay in the hospital though most patients can return home the same day as the procedure.

Is cardiac ablation worth the risk?

Catheter ablation does have some serious risks, but they are rare. Many people decide to have ablation because they hope to feel much better afterward. That hope is worth the risks to them. But the risks may not be worth it for people who have few symptoms or for people who are less likely to be helped by ablation.
