NCT05081310

Brief Summary

There is still unresolved question whether isolation of superior vena cava (SVC) in conjunction to conventional pulmonary vein isolation (PVI) improves outcomes in the treatment of paroxysmal atrial fibrillation. The investigators are conducting a randomized study to determine if SVC isolation (in addition to pulmonary vein isolation) with the cryoballoon technology can improve freedom from atrial arrhythmias in one year follow up after the ablation.

Outcome Measures

Primary Outcomes (1)

  • efficacy

    number of patients free of any atrial arrhythmias during the one year of follow up (occurrence of any atrial arrhythmia longer than 30 seconds, detected by Holter EKG or 12 lead EKG will be considered as treatment failure)

    one year

Secondary Outcomes (2)

  • feasibility

    during the procedure

  • safety

    one year

Study Arms (2)

SVC arm

EXPERIMENTAL

Patients who will receive SVC isolation by the means of cryoballoon after the PVI procedure

Device: superior vena cava isolation

PVI arm

ACTIVE COMPARATOR

Patients who will receive convectional cryoballoon PVI procedure

Device: pulmonary vein isolation

Interventions

SVC isolation by the means of cryoballoon

SVC arm

conventional pulmonary vein isolation by the means of cryoballoon

PVI arm
