Pulsed Field Ablation (PFA) for Atrial Fibrillation in Florence, Italy: What Patients Need to Know

Introduction


Atrial fibrillation is the most common sustained cardiac arrhythmia in adults. It can present with palpitations, shortness of breath, exercise intolerance, fatigue, or an irregular heartbeat, though in some cases it may be entirely asymptomatic. Managing atrial fibrillation requires careful evaluation, as treatment extends beyond symptom relief to include stroke prevention, rate or rhythm control, and addressing the underlying cardiovascular risk profile.


Recent advances in catheter ablation technology have expanded the options available to patients with atrial fibrillation. One of the most significant developments is Pulsed Field Ablation (PFA), also known as electroporation, a non-thermal energy source that is now available in Florence, Italy.

I perform PFA ablation procedures at Villa Donatello, a premium private clinic in Florence, together with my colleagues Dr. Andrea Colella and Dr. Luca Panchetti. On April 30, 2026, we carried out one of the first PFA procedures performed in a private healthcare facility in Italy (link). This article explains what PFA means for patients considering atrial fibrillation ablation, in scientifically accurate but accessible terms.

What Is Catheter Ablation for Atrial Fibrillation?

Catheter ablation is an interventional procedure used to treat certain forms of atrial fibrillation. In most cases, the primary goal is to achieve pulmonary vein isolation (PVI) by electrically disconnecting the pulmonary veins, which are the structures where the abnormal electrical impulses that trigger atrial fibrillation most commonly originate.

The procedure is performed by advancing catheters through the femoral veins into the heart. Through these catheters, the electrophysiologist creates controlled lesions in the cardiac tissue to interrupt the electrical circuits responsible for the arrhythmia.

Ablation is not automatically indicated for every patient with atrial fibrillation. Its appropriateness depends on several factors: the type of atrial fibrillation (paroxysmal, persistent, or long-standing persistent), symptom severity, age, comorbidities, left atrial size, response to antiarrhythmic drugs, history of recurrence, and realistic clinical goals.


What Is PFA (Pulsed Field Ablation)?

Pulsed Field Ablation uses ultra-short, high-intensity electrical pulses to cause selective and irreversible damage to the cardiac cells involved in the arrhythmia, without relying on thermal energy. Unlike radiofrequency ablation (which uses heat) and cryoablation (which uses extreme cold), PFA employs a fundamentally non-thermal mechanism.

The underlying principle is irreversible electroporation: the electrical field creates permanent pores in the cell membrane, leading to cell death. This is distinct from reversible electroporation, which is used in other medical applications: in cardiac PFA, the effect is deliberately irreversible and definitive.


A key advantage of PFA is its tissue selectivity. Cardiac myocytes have a lower electroporation threshold than surrounding structures such as the esophagus, the phrenic nerve, and the coronary arteries. This means the energy can be calibrated to ablate myocardial tissue while sparing adjacent structures, a particularly relevant advantage when working near the posterior esophageal wall and the right phrenic nerve, where thermal injury has historically been a concern with conventional energy sources.

Clinical data support these premises. In the ADVENT trial, published in the New England Journal of Medicine, PFA demonstrated non-inferiority to radiofrequency and cryoablation for pulmonary vein isolation, with a favorable safety profile. Large-scale registry data from the MANIFEST-PF and MANIFEST-17K studies have further confirmed a low rate of esophageal and phrenic nerve complications.


What Does PFA Mean for Patients?

The availability of PFA in Florence does not mean there is a single "best technique" for everyone. It means the electrophysiologist has an additional tool to tailor treatment to each patient's specific clinical profile.


The potential advantages of PFA include:

  • A non-thermal mechanism of action, reducing the risk of collateral thermal injury

  • Greater selectivity for myocardial tissue over surrounding structures

  • Shorter procedural times: in our experience, significantly shorter than conventional ablation procedures

  • A favorable safety profile in available clinical data

  • Efficacy at least comparable to established techniques in appropriately selected patients, particularly in paroxysmal atrial fibrillation


However, it is important to avoid oversimplification. PFA does not eliminate the need for a correct clinical indication, does not guarantee zero recurrence risk, and does not replace post-procedural follow-up. As with any atrial fibrillation treatment, outcomes depend on patient selection, procedural strategy, center experience, and comprehensive cardiovascular risk management.

I have written a detailed comparison of PFA versus radiofrequency ablation — including efficacy, safety, and clinical scenarios where each technique may be preferred — in a dedicated article.


PFA Ablation at Villa Donatello, Florence

I perform atrial fibrillation ablation using PFA (electroporation) at Villa Donatello in Florence, Italy, alongside Dr. Andrea Colella and Dr. Luca Panchetti. On April 30, 2026, we performed one of the first PFA procedures carried out in a private hospital in Italy.

PFA ablation complements our established radiofrequency and cryoablation capabilities, allowing us to select the most appropriate energy source for each individual patient's anatomy and clinical profile.

Consultations are available in English, Italian, and Spanish. For international patients and expats living in Tuscany, I offer dedicated electrophysiology consultations with full English-language support, from initial evaluation through to procedural planning and follow-up.

To discuss whether PFA ablation may be appropriate in your case, you can book an electrophysiology consultation.


When to Seek an Electrophysiology Evaluation


An electrophysiology consultation may be valuable if you experience:

  • Symptomatic atrial fibrillation despite medical therapy

  • Recurrent episodes of palpitations or irregular heartbeat

  • Arrhythmia recurrence after previous ablation

  • Poor tolerance of antiarrhythmic medications

  • Uncertainty about whether catheter ablation is right for you

  • A desire for a second opinion on your current treatment strategy


A specialist evaluation allows us to characterize the arrhythmia, assess your individual risk profile, review anticoagulation needs, evaluate drug therapy, and determine whether an ablation procedure is indicated.


Conclusion

The introduction of PFA in Florence represents a meaningful step forward in catheter ablation for atrial fibrillation. Its value lies not only in the technology itself, but in the ability to integrate it into a personalized clinical pathway : one based on accurate diagnosis, appropriate indication, and dedicated follow-up.

For patients, this means access to increasingly advanced therapeutic options, within the framework of an individualized, careful, and thorough medical evaluation.

If you have documented atrial fibrillation, recurrent palpitations, or questions about ablation treatment, you are welcome to schedule a consultation at my practice in Florence for a comprehensive assessment.
