Catheter Ablation (Atrial Fibrillation Ablation)
What is the purpose of an atrial fibrillation ablation?
Catheter ablation is a minimally invasive procedure to help treat atrial fibrillation (AF). Ablation reduces the likelihood of further episodes and increases the likelihood of remaining in normal sinus rhythm.
How is an atrial fibrillation ablation performed?
On the day of the procedure, the anesthesia team will administer medications to make you go to sleep and a breathing tube may be placed. Your doctor will then insert small, flexible tubes called catheters through the veins in your groin. Once the catheters are inserted, a computer is used to create a detailed map of your heart. Your doctor will then use heat (radiofrequency) or cold (cryoablation) energy to change the electrical properties of irritable tissue in the left upper chamber of the heart. This will help block the abnormal electrical signals that cause atrial fibrillation.
After the procedure, you will be on bedrest for several hours to prevent bleeding. Most patients are discharged on the same day after their bedrest ends, but some are monitored overnight before being discharged. Your doctor will prescribe a proton pump inhibitor such as pantoprazole (Protonix) to help protect your stomach and esophagus (food pipe). This medication is typically taken for one month after the procedure. Protonix is taken to help reduce any irritability in the esophagus post ablation.
How safe is the procedure?
This procedure is widely used and has become very safe. Your doctor will discuss all possible risks with you prior to the procedure.
When should an atrial fibrillation ablation be discussed?
Atrial fibrillation ablation is not a good option for everyone. Your doctor will carefully consider your case and discuss whether you would benefit from this treatment.
It is important to note that an atrial fibrillation ablation does not typically allow you to stop taking blood thinners and some patients may require more than one ablation. It is sometimes necessary to continue taking medications to maintain normal sinus rhythm even after this procedure.
