NCT06698159

Brief Summary

The WIDER PVI study is a multicentre randomized clinical trial to compare the efficacy of antral versus extended antral PVI in patients with paroxysmal or persistent AF undergoing this procedure using a cryoablation balloon capable of 28 mm diameter (antral isolation) or 31 mm diameter (extended antral isolation) applications. The aim is to evaluate an objective of superiority of the extended antral isolation strategy versus antral isolation in the recurrence of atrial tachyarrhythmias at 1-year follow-up, both in episodes of \>30 seconds duration and in overall arrhythmic load.

Outcome Measures

Primary Outcomes (3)

  • Recurrence of atrial tachyarrhythmia

    Presence of atrial fibrillation, atrial flutter, atrial tachycardia in which the atrial rate exceeds 180 beats per minute, lasting more than 30 seconds after the blanking period (8 weeks) and without pharmacological anti-arrhythmic treatment during 12 months of follow-up with continuous ECG monitoring (in patients with continuous implantable monitor) or combined (in patients without implantable monitor), by optical heart rate monitoring combined with programmed intermittent ECG and in response to detection of heart rate irregularity).

    From enrollment to the end of follow up, assessed up to 12 months

  • Arrhythmic load

    Percentage of time the patient has atrial tachyarrhythmia (atrial fibrillation, atrial flutter, atrial tachycardia in which the atrial rate exceeds 180 beats per minute) over the total monitored time.

    From enrollment to the end of follow up, assessed up to 12 months

  • Arrhythmic load

    Total duration of the longest episode of atrial tachyarrhythmia for each patient (cut off point: 60 minutes)

    From 0 up to 60 minutes for every atrial tacharrhythmia detected in each patient

Secondary Outcomes (4)

  • Acute effectiveness

    Every measure is assessed through procedure time, an average of 180 minutes

  • Effectiveness in follow-up

    Until the end of the study

  • Safety

    Until the end of the study

  • Acute effectiveness

    Every measure is assessed through procedure time, an average of 180 minutes

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age over 18 years old.
  • Previous diagnosis of paroxysmal or persistent atrial fibrillation less than 2 years after diagnosis.
  • Clinical indication to undergo a pulmonary vein isolation procedure using balloon cryoablation.

You may not qualify if:

  • Previous endocardial or surgical ablation of atrial fibrillation.
  • Severe frailty (Clinical Frailty Scale score 7 or higher) or life expectancy less than 1 year.
  • Inability to understand or give informed consent.
  • Performance of other left atrial ablations in addition to pulmonary veins.
  • Need to use another catheter in addition to the cryoablation catheter to complete pulmonary vein isolation.
  • Contraindication to anticoagulation or intolerance to heparin.
  • Presence of intra-atrial thrombus.
  • Reversible cause of atrial fibrillation.
  • Severe mitral or aortic valve disease.
  • Congenital heart disease.
  • Pregnancy or the prospect of pregnancy in the next 12 months.
