Eligibility
Inclusion criteria
Inclusion criteria: - Patients age is >= 18 years - Patients with persistent or longstanding persistent atrial fibrillation. - Patients undergoing a first time ablation procedure for persistent atrial fibrillation - AF must be recorded at least once by ECG, holter, telemetry, loop recorder or internal device. - Patients must give informed consent to participate
Exclusion criteria
Exclusion criteria: - Patients suffering from paroxysmal atrial fibrillation. - Patients with any exclusion criteria or contra-indications for electrophysiologic study and ablation in the left atrium, such as pregnancy or presence of a left atrial thrombus - Prior PVAI with RF or cry ablation
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary objective of the study is to evaluate which ablation strategy- PVAI alone or PVAI plus limited ablation of CFAE*s in a specific region of the left atrium- is most effective in treating persistent and longstanding persistent atrial fibrillation measured by success at 12 months after 1 or 2 procedures. Success is defined as freedom from recurrences following the 3-month blanking period in the absence of Class I and III AAD therapy. Recurrence is defined as recurrence of atrial fibrillation, atrial flutter or atrial tachycardia of at least 30 seconds* duration that is documented by an ECG or device recording system more than 3 months following AF-ablation. | — |
