Pulsed Field Ablation (PFA) | Next-Generation Atrial Fibrillation Treatment | MediHeart Medical Center Güzelyurt
Pulsed Field Ablation (PFA) is one of the next-generation catheter ablation methods used in the treatment of atrial fibrillation. Who is PFA treatment performed on, how is it performed, and what is the treatment process like? Get detailed information with the evaluations of Prof. Dr. Osman Beton.
Pulsed Field Ablation (PFA)
Atrial fibrillation (AF) is one of the most common heart rhythm disorders, developing due to irregular electrical activity in the upper chambers of the heart. This rhythm disorder, which can cause symptoms such as palpitations, shortness of breath, rapid fatigue, decreased exercise capacity, and a significant decline in quality of life, can also increase the risk of stroke when not properly managed. Today, alongside medical therapies, catheter ablation holds an important place in the treatment of atrial fibrillation. Thanks to technological advancements, ablation methods are continuously evolving, one of which is Pulsed Field Ablation (PFA) technology.
Pulsed Field Ablation is a next-generation ablation method aimed at creating a selective cellular effect in targeted cardiac tissue by using controlled electric fields instead of high temperatures or extreme cold. This technology is based on the principle of irreversible electroporation (IRE). The objective is to neutralize the electrical foci causing atrial fibrillation while contributing to the preservation of certain surrounding tissues. However, it may not be suitable for every patient, and the treatment decision should be made after a detailed electrophysiological evaluation.
At MediHeart Medical Center Güzelyurt Cardiology Department, the Pulsed Field Ablation procedure is evaluated by our Cardiology Specialist Prof. Dr. Osman Beton in accordance with current scientific data and international cardiology guidelines. A personalized treatment plan is created by considering the patient’s type of rhythm disorder, cardiac structure, and clinical characteristics.
What is Pulsed Field Ablation (PFA)?
Pulsed Field Ablation is one of the next-generation catheter ablation methods used in the treatment of atrial fibrillation. During the procedure, short-duration and high-intensity electric fields are applied to create irreversible electroporation in target heart cells. Thus, the goal is to eliminate the electrical activity of the regions causing the rhythm disorder.
While conventional radiofrequency ablation acts with thermal energy and cryoablation acts with cold energy, PFA operates through an entirely different biophysical mechanism. For this reason, it has been among the prominent innovative technologies in electrophysiology in recent years.
Who Can Undergo Pulsed Field Ablation?
PFA treatment is not applied to every patient with atrial fibrillation. The treatment decision is made following a detailed cardiological evaluation of the patient.
Generally, evaluations can be made for:
Patients with paroxysmal atrial fibrillation
Cases of persistent atrial fibrillation deemed appropriate
Patients scheduled for catheter ablation
Individuals targeted for rhythm control
Patients for whom the cardiology specialist deems PFA technology suitable
The definitive treatment option is determined in line with the patient’s clinical condition, cardiac anatomy, and current scientific criteria.
Which Tests Are Performed Before the Procedure?
A detailed cardiological evaluation is performed before planning the PFA procedure.
When deemed necessary:
Cardiology examination
Electrocardiogram (ECG)
Holter rhythm monitoring
Echocardiography
Blood tests
Transesophageal Echocardiography (TEE)
Cardiac CT or Cardiac MRI
Three-dimensional electrophysiological mapping planning
can be applied.
Thanks to these evaluations, both patient safety is increased and the most appropriate ablation strategy is determined.
How is Pulsed Field Ablation Performed?
Pulsed Field Ablation is an interventional cardiology procedure performed in the electrophysiology laboratory. During the procedure, access to the heart is usually achieved through the vein in the groin area using thin catheters, and the left atrium is entered via a specialized transseptal technique.
Using three-dimensional mapping systems, pulmonary veins and target ablation areas are thoroughly evaluated. Subsequently, short-duration electric fields are applied through a specialized PFA catheter, aiming to isolate the electrical foci causing atrial fibrillation.
The duration of the procedure may vary depending on the patient’s cardiac anatomy, the type of rhythm disorder, and the ablation plan to be implemented. After the procedure is completed, the patient is kept under observation for a certain period, and a discharge plan is made according to their general health status.
What Are the Advantages of Pulsed Field Ablation (PFA)?
Pulsed Field Ablation (PFA) is one of the next-generation catheter ablation technologies developed for the treatment of atrial fibrillation. Differing from conventional ablation methods, it is considered one of the significant innovations in electrophysiology due to its use of controlled electric fields instead of thermal energy. However, as with any new technology, treatment selection must be made strictly according to the clinical characteristics of the patient.
Possible advantages that PFA treatment may provide in suitable patients include:
It may contribute to bringing atrial fibrillation attacks under control.
It may help maintain normal heart rhythm.
It may contribute to alleviating complaints such as palpitations, shortness of breath, and reduced exercise capacity.
It may support the effective performance of pulmonary vein isolation.
It may offer a distinct approach toward preserving surrounding tissues thanks to its selective cellular action principle.
It may contribute to improving daily quality of life.
Identical clinical results cannot be guaranteed in every patient. Treatment success depends on many factors, including the type and duration of atrial fibrillation, the presence of structural heart disease, lifestyle habits, and regular follow-up.
Are There Risks to Pulsed Field Ablation?
Pulsed Field Ablation is considered among safe interventional cardiology procedures when performed by experienced electrophysiology teams. Nevertheless, as in any interventional procedure, certain risks cannot be completely eliminated.
A detailed evaluation is performed before the procedure to review the patient’s overall health status, current medications, and existing cardiac conditions. All necessary precautions are taken regarding access site vascular complications, temporary rhythm changes, or other rare interventional complications. During treatment planning, expected benefits and potential risks are evaluated together to make a personalized decision.
Post-Procedure Recovery Process
Patients are kept under observation for a certain period following the PFA procedure. The time to discharge may vary based on the extent of the intervention, the overall health status of the patient, and post-procedure findings.
Strict compliance with medications recommended by the cardiology specialist in the first few weeks is of great importance. In particular, blood thinner therapy and required rhythm-regulating medications must be used for the duration specified by the physician. Through follow-up examinations, cardiac rhythm is evaluated regularly, and the treatment process can be replanned if necessary.
In some patients, temporary rhythm irregularities may be observed during the first few months after ablation. This situation does not always signify treatment failure and must strictly be evaluated by a cardiology specialist.
Importance of Experience in Pulsed Field Ablation
PFA technology is one of the interventional cardiology applications that require advanced electrophysiology infrastructure and an experienced team. Correct utilization of three-dimensional mapping systems, detailed evaluation of pulmonary vein anatomy, and determination of the appropriate ablation strategy constitute critical stages of treatment.
At MediHeart Medical Center Güzelyurt Cardiology Department, Prof. Dr. Osman Beton decides on the necessity of Pulsed Field Ablation by thoroughly evaluating patients’ clinical findings, ECG and Holter recordings, echocardiography results, and other imaging methods. The treatment plan is established on a personalized basis for every patient in accordance with current international electrophysiology guidelines.
