Conditions

Symptomatic persistent atrial fibrillation: atrial fibrillation, that lasts longer than 7 days, including episodes that are terminated by cardioversion, either with drugs or by direct current cardioversion, after 7 days or more. Episodes of atrial fibrillation have to be accompanied by symptoms. MedDRA version: 20.0 Level: LLT Classification code 10071667 Term: Persistent atrial fibrillation System Organ Class: 100000004849

Design outcomes

Primary

MeasureTime frame
Main Objective: We aimed to study whether continued ADT (antiarrhythmic drug treatment) (ADT ON) beyond the 3 month blanking period reduces recurrrence of atrial tachyarrhyhtmia (ATA) in the first year after contact-force guided pulmonary vein isolation (PVI) for persistent AF.;Secondary Objective: Secondary Endpoints: Time to persistent AF ATA recurrence in patients with early peristent AF (defined as AF =3 months) Incidence of repeat ablation Unscheduled visits and hospitalisation ADT or ablation related adverse events QOL and symptoms Outcome after repeat ablation ;Primary end point(s): Primary Endpoint: Any documented ATA (atrial fibrillation, AF, atrial tachycardia, AT, atrial flutter, AFL) lasting >30s from 3 months through 12 month follow-up after the first procedure ;Timepoint(s) of evaluation of this end point: - Enrollment - (T0) PVI - (T1) 1 month - (T3) 3 months +/- 30days - (T6) 6 months +/- 30days - (T12) 12 months +/- 30 days

Secondary

MeasureTime frame
Secondary end point(s): Secondary Endpoints: Time to persistent AF ATA recurrence in patients with early peristent AF (defined as AF =3 months) Incidence of repeat ablation Unscheduled visits and hospitalisation ADT or ablation related adverse events QOL and symptoms Outcome after repeat ablation ;Timepoint(s) of evaluation of this end point: - Enrollment - (T0) PVI - (T1) 1 month - (T3) 3 months +/- 30days - (T6) 6 months +/- 30days - (T12) 12 months +/- 30 days
