NCT01696344

Brief Summary

This prospective study aims to investigate if termination of atrial fibrillation (AF) after pulmonary vein antrum isolation (PVAI) without additional ablation of non-PV triggers, in long-standing persistent (LSP) AF, is enough to ensure long-term success.

Outcome Measures

Primary Outcomes (1)

  • AF recurrence

    Any episode of AF/AT longer than 30 seconds will be considered as recurrence. Episodes that occur during the first 3 months of the procedure (blanking period) will not be considered as recurrence.

    3 years

Study Arms (2)

Cohort 1

No additional ablation after AF termination(PVAI only)

Procedure: PVAI

Cohort 2

Additional ablation of extra-PV triggers before and after isoproterenol-challenge after AF termination (PVAI + ablation of extra-PV triggers)

Procedure: PVAI + ablation of extraPV triggers

Interventions

PVAIPROCEDURE
Also known as: Pulmonary vein antrum isolation
Cohort 1

PVAI followed by ablation of extra-PV triggers originating from sites other than pulmonary veins such as superior vena cava, ligament of Marshall, coronary sinus, crista terminalis, left atrial (LA) posterior wall and LA appendage

Cohort 2
