 How is AF treated?

How is AF treated?

There are different ways to treat AF depending on your symptoms and the information gathered from your diagnostic tests. Your doctor will discuss the options with you and help you decide what treatment is the most appropriate for your condition and your lifestyle.

Healthy lifestyle

Whatever treatment plan is chosen, you should support it with good lifestyle choices that are well recognised to have a positive impact on heart health and general wellbeing.1

Having a healthy lifestyle doing a regular exercise.

EXERCISE REGULARLY

Eat a healthy diet and maintain a healthy weight

EAT A HEALTHY DIET AND MAINTAIN A HEALTHY WEIGHT

restrict and eliminate alcohol and caffeine.

RESTRICT/ELIMINATE ALCOHOL AND CAFFEINE

Stop smoking  to have a healthy life.

STOP SMOKING

Cardioversion

Cardioversion can be a scheduled procedure or used in emergencies.

Cardioversion can be a scheduled procedure or used in emergencies.
It involves delivering low-energy shocks to the heart in order to quickly restore a normal heart rhythm. Cardioversion can also be conducted with medication. While the risks are low, cardioversion is not generally a long-term solution. 

 Drug treatments

Drug therapy is often the first course of treatment for AF. A variety of different drug treatments are available, which fall into two main types:
 

  • Anti-arrhythmia drugs, such as sodium channel blockers and beta blockers, intended to control the rhythm and speed at which your heart beats
  • Blood-thinning drugs intended to reduce the risk of stroke by limiting the blood’s ability to clot

Your doctor will assess how well you tolerate the drugs, how they impact your lifestyle and how well they are controlling your AF and risk of stroke. This will help determine if they are a satisfactory treatment for you or if a different approach should be considered. 

Left atrial appendage closure (LAAC)

Blood is pumped from the left upper chamber of the heart (left atrium) to all parts of the body, including the brain. The left atrial appendage is the part of the heart where blood can pool and clot if the upper chambers (atria) of the heart are not contracting properly. By closing off this „clot-making reservoir“, the risk of stroke is significantly reduced and the need for long-term blood-thinning drugs can be avoided.

Cardiac ablation*

Cardiac ablation aims to treat the cause of AF by neutralising the locations in your heart that are transmitting the random or abnormal electrical signals that are disrupting its rhythm.
These problem signals often reach the heart via the joining points where the four pulmonary veins delivering blood from the lungs enter the left atrium.
A common form of cardiac ablation called pulmonary vein isolation (PVI) targets these specific joining points to stop them being able to transmit abnormal signals from the veins to the left atrium. Cardiac ablation is a minimally invasive procedure performed by advancing long thin tubes called catheters through blood vessels into your heart from a small incision in your groin. Once in position, a catheter is used to deliver energy to targeted points in your heart to "neutralise" the problem tissue so it will no longer be able to transmit the electrical signals that are causing your AF.

7-8 out of 10 patients with paroxysmal (intermittent) AF are free from AF for the first year after their cardiac ablation.2, 10-13 As AF is a chronic disease, the recurrence rate increases through 5 years and repeat ablation procedures might be needed.9

Ablation technology has evolved over the years to increase the precision and efficiency of the procedure and to minimise the risk of damage to healthy heart tissue or nerves. The latest innovation in cardiac ablation is pulsed-field ablation (PFA).2

Radiofrequency ablation (RFA)

Radiofrequency ablation (RFA) uses high-frequency energy to create extreme heat to neutralise target tissue

Cryoablation

Cryoablation uses extreme cold to neutralise target tissue

Pulsed field ablation (PFA)

Pulsed field ablation uses microsecond electrical pulses to neutralise target tissue

FARAPULSE™ Pulsed Field Ablation (PFA)* 

The FARAPULSETM PFA system has been specifically developed to offer a next-generation ablation method with excellent precision and accuracy. The "petals" of the distinctive flower-shaped catheter tip are straightened out while the catheter is being advanced through your veins to your heart. Once in position, they are opened up and adjusted to different shapes to fit the anatomy of the entrance from your pulmonary veins. Unlike radiofrequency and cryoablation, PFA works with pulsed, high-energy electrical fields and is therefore a non-thermal ablation method. Because cardiac cells are more sensitive to this electrical field, surrounding structures, such as the oesophagus or the phrenic nerve are usually not affected. PFA aims at selectively targeting and neutralising the tissue responsible for your AF.

Extensive studies have shown PFA with FARAPULSE™ to be safe, with minimal side effects.2, 8, 14-16 Patients have also reported minimal pain and fast recovery after their FARAPULSE™ PFA procedure.17, 18 


 *Not all types of atrial fibrillation are suitable for treatment with cardiac ablation or with the FARAPULSE™ Pulsed Field Ablation System. Your doctor will be able to advise you if it could be a suitable treatment for you according to diagnostic and treatment guidelines.
**Study showed 78% of patients free from paroxysmal AF in the first year post cardiac ablation were still free from AF after 4 years.9
