Beskrivning
Inclusion Criteria:
- History of paroxysmal AF.
- Scheduled to undergo AF catheter ablation with the FARAPULSE (Boston Scientific) PFA system.
Exclusion Criteria:
- Any contraindication to AF catheter ablation.
- History of previous left atrial ablation.
- Need for additional ablation beyond pulmonary vein isolation.
- Inability to provide written informed consent.
- Any factor that, in the investigator's judgment, renders the patient unsuitable for participation or may compromise their safety.
- eGFR < 30 mL/min/1.73 m2
- NYHA class III/IV heart failure
- Major cardiovascular events within 90 days
- Secondary AF owing to reversible causes
- Intracardiac thrombus or other conditions making left atrial instrumentation unsafe
- Severe valvular disease

Intervention / Behandling |
|---|---|
|
Övrig: ICE
Intracardiac echocardiography-guided group
|
Ablation procedure (electrical isolation of the pulmonary veins) will be performed according to routine clinical practice.
In the ICE group, positioning of the ablation catheter and confirmation of contact with the targeted tissue will be performed under ICE guidance.
In the mapping group, guidance will be performed using three-dimensional electroanatomical mapping with the FARAVIEW system (OPAL HDx, software version 7.0, Boston Scientific).
PFA will be delivered using field-tag feature ensuring number of applications and stacking as suggested by IFU.
In the mapping group, the use of ICE will only be allowed to guide the transseptal puncture in order to ensure procedural safety in both groups.

Åtgärdsbeskrivning |
Tidsram |
|---|---|---|
|
Arrhythmia-free survival
Tidsram: up to 12 months
|
Primary efficacy endpoint: Number of patients without atrial arrhythmia recurrence (AF, atrial flutter, atrial tachycardia) off antiarrhythmic drug therapy and without the need for electrical cardioversion or repeat ablation, after a blanking period of 2 months.
A recurrence is defined as any episode of atrial tachyarrhythmia recorded on standard 12-lead ECG or any episode lasting ≥6 minutes on Holter monitor (or CIED with atrial sensing capabilities).
|
up to 12 months
|
|
Complications
Tidsram: up to 12 months
|
Composite primary safety endpoint: Number of participants experiencing at least one of the following prespecified complications (major safety events): Stroke, transient ischemic attack, or systemic embolism Coronary spasm Myocardial infarction Cardiac tamponade Clinically relevant esophageal complication Clinically relevant pulmonary vein stenosis Diaphragmatic paralysis persisting for more than 6 months Acute kidney injury Bleeding requiring transfusion Major vascular complication Pericarditis or vagal nerve injury Heart failure or pulmonary edema Sudden death within 30 days of the procedure Any device- or procedure-related death For the composite primary safety endpoint, each participant will be counted only once, regardless of the number or type of qualifying events experienced. |
