NCT05328882

Brief Summary

This is a prospective, single-arm study conducted in University Hospital of Split, Department of Cardiology. Patients treated with PFA for symptomatic paroxysmal atrial fibrillation will be asked to participate in the study. An implantable loop recorder (ILR) will be placed immediately after the PFA procedure for rhythm monitoring. Early recurrences will be subsequently divided into very early recurrences (up to 1 month post-procedure) and early recurrences (1-3 months post-procedure). Late recurrences will be defined as those 3 to 12 months post-procedure. Patients will be monitored routinely through follow up visits during which ILR will be interrogated and eventual symptoms will be assessed. Follow-up visits will be scheduled 1, 3, 6, 12 months post-procedure. Median follow-up will be 12 months. Data for the study will be obtained from a loop monitor to assess the arrhythmia burden during follow-up visits in the University Hospital of Split Arrhythmia Clinic.

Outcome Measures

Primary Outcomes (1)

  • Number of participants with AF recurrence 3-12 months post-procedure

    Number of participants with AF recurrence 3-12 months post-procedure (AF burden defined by loop recorder findings)

    12 months

Secondary Outcomes (2)

  • Adverse event rate

    12 months

  • Number of patients with very early AF recurrence (within 1 month post procedure)

    12 months

Study Arms (2)

ERAF after PFA

Patients with an early recurrence after pulsed field ablation of paroxysmal atrial fibrillation.

Other: Monitoring of paroxysmal atrial fibrillation recurrence after pulsed field catheter ablation

no ERAF after PFA

Patients without an early recurrence after pulsed field ablation of paroxysmal atrial fibrillation.

Other: Monitoring of paroxysmal atrial fibrillation recurrence after pulsed field catheter ablation

Interventions

The implanted loop recorder will be interrogated to see how many patients had an early recurrence of AF (up to 3 months after the procedure). Then the late recurrence rate will be compared (3-12 months post-procedure) between groups with and without early recurrences.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients with symptomatic paroxysmal atrial fibrillation after at least one failed or intolerant group I or III of antiarrhythmic drug that are eligible for PFA and are willing and able to provide informed consent.

You may qualify if:

  • Age \>18
  • Index PFA procedure after one failed or intolerant group I or III of the antiarrhythmic drug in patients with symptomatic paroxysmal AF (AF with self-terminating episodes lasting no longer than 7 continuous days)
  • Willing and able to provide informed consent.

You may not qualify if:

  • Any known contraindication to AF ablation or anticoagulation.
  • History of previous left atrial ablation or surgical treatment.
  • Secondary AF due to reversible or non-cardiac cause such as thyroid disease and electrolyte imbalance.
  • Asymptomatic AF patients, persistent AF, permanent AF patients.
  • History of clotting or bleeding disease or cryoglobulinemia.
  • Pregnant or lactating.
  • Other conditions that may make the patient a poor candidate for procedure such as mental illness, terminal illness, vulnerable patient population.
