What happens in this surgery?
- Thin, flexible catheters are inserted through a vein, typically in the groin, and guided to the heart.
- The catheter delivers controlled radiofrequency (heat) energy to the identified extra electrical pathway.
- This heat creates tiny, permanent scars that block the abnormal electrical signals.
- The procedure aims to restore the heart's normal electrical conduction and rhythm.

Post Surgery Recovery
What to expect after your procedure
Following catheter ablation, patients typically remain in the hospital for several hours or overnight for observation. You will be required to lie flat for a few hours to minimize the risk of bleeding at the catheter insertion site, usually in the groin. It's common to experience mild pain, soreness, or bruising at this site. Most individuals can resume light daily activities within a few days, though strenuous exercise, heavy lifting, and intense physical activity should be avoided for approximately one week. Your medical team will provide detailed post-procedure instructions regarding activity restrictions, medication management, and scheduling follow-up appointments to monitor your recovery and heart rhythm. It is crucial to watch for any unusual symptoms such as fever, increased pain, significant swelling, or excessive bleeding at the insertion site, and to contact your doctor immediately if they occur. While many patients experience immediate relief, the full benefits of the ablation and complete healing of the heart tissue may take several weeks.

Recovery & Wellness Tips
- Discuss all current medications, supplements, and allergies with your doctor. You may need to stop certain blood thinners or heart rhythm medications prior to the procedure.
- Undergo pre-procedure diagnostic tests, which may include an electrocardiogram (ECG), blood tests, and an electrophysiological (EP) study to precisely map your heart's electrical activity.
- Follow specific fasting instructions, typically avoiding food and drink for 6-8 hours before the ablation.
- Arrange for someone to drive you home after the procedure, as you will not be able to operate a vehicle due to sedation.
