Treatment: Atrial Fibrillation (AF) Ablation

Atrial fibrillation ablation is an invasive procedure that helps maintain a normal heart rhythm.

Why you might need?

Atrial fibrillation (AF) can cause some unpleasant symptoms like shortness of breath and heart palpitations. It also greatly increases the risk of stroke and anticoagulation medicines pose their own risks.

Ablation controls the symptoms of atrial fibrillation, but usually does not eliminate the needs for medication for stroke prevention.

If you have atrial fibrillation that has lasted for 7 days or less, ablation may be more likely to work long-term. It may not work as well long-term if you’ve had more persistent atrial fibrillation. Your Cardiologist will decide if you need AF Ablation.

Treatment Info

Atrial Fibrillation (AF) is a chaotic heart rhythm.
Atrial fibrillation ablation helps maintain a normal heart rhythm. Ablation uses small burns or freezes to cause some scarring on the inside of the heart that helps to break up electrical signals that cause an irregular heart rhythm. This can return your heart to normal sinus rhythm (SR).

What happens during Atrial Fibrillation Ablation?

You will usually have a general anaesthetic. At OneWelbeck we can offer three different types of ablation, and your cardiologist will advise on which method is best-suited to your individual needs.

  1. Cryoablation: your Cardiologist will put catheters into a blood vessel in the groin and thread it up to the heart giving them access to the collecting chambers (Atria) inside your heart. The catheter is then used to scar a small area of the heart by making small freezes.
  2. Radio frequency ablation: energy will be used to make small burns inside the heart that scars and shrinks damaged tissue. The scarring helps prevent the heart from conducting the abnormal electrical signals that cause atrial fibrillation.
  3. Pulsed field ablation: we are proud to be the first private facility in the UK to offer the FARAPULSE™ Pulsed Field Ablation (PFA) System from Boston Scientific to treat paroxysmal atrial fibrillation (AF) patients. The tissue-selective FARAPULSE™ PFA System has emerged as a promising energy source for cardiac ablation, specifically pulmonary vein isolation to treat paroxysmal AF. Leading with safety, the FARAPULSE™ PFA System makes durable cardiac lesions in seconds while sparing non-target tissue.

You will usually be sent home the same day.

Treatment Risks

Most who undergo atrial fibrillation ablation have a successful outcome, although there are risks including:

  • In the groin – bleeding, infection or pain from the catheter insertion
  • Damage to the blood vessels from the catheter
  • Puncture to the heart
  • Damage to the heart
  • Blood clots
  • Narrowing of the pulmonary veins
  • Radiation exposure

You can discuss any concerns you may have with your OneWelbeck Consultant Cardiologist.
