Approaches to Catheter Ablation for
Persistent Atrial Fibrillation
- APPROACHES
- Ablation with pulmonary-vein isolation alone
- Pulmonary-vein isolation plus ablation of complex fractionated electrograms
- Pulmonary-vein isoation plus linear ablation
- Ablation with pulmonary-vein isolation alone
- CRITERIA
- INCLUSION
- Older than 18 yars old
- They should have symptomatic persistent atrial fibrilation
- They have to be undergoing ablation for the first time
- All participating patients provided written informed consent
- Older than 18 yars old
- EXCLUSION
- Paroxysmal atrial fibrilation
- Sustained atrial fibrilation lasting more than 3 years
- Left atrial diameter of 60mm or greater
- Paroxysmal atrial fibrilation
- INCLUSION
- PATIENTS WERE RANDOMLY ASSIGNED
- IN THIS WAY
- Pulmonary-vein isolation alone
- Pulmonary-vein isolation plus ablation of compex fractionated electrograms
- Pulmonary-vein isolation plus linear ablation across the roof of the left atrium and in the mitrial valve ithmus
- Pulmonary-vein isolation alone
- IN THIS WAY
- POCEDURES
- It was used radio diofrequency energy delivered by a catheter with an open, irrigated tip
- Antigulation was continued after ablation for a minimum of 3 months
- Before ablation, tratment with antiarrhythmic medications was stopped and patients recived oral anticoagulation for at least 4 weeks
- It was used radio diofrequency energy delivered by a catheter with an open, irrigated tip
- CLINICAL ASSESTENTS
- EKG 12 lead
- Holter-monitor
- Trans-telephonic monitor
- EKG 12 lead
- STUDY OUTCOMES
- freedom from any documented episode of atrial fibrillation lasting longer than 30 seconds and
occurring after the performance of a single ablation procedure
- Main secondary outcomes included freedom from documented atrial fibrillation after two ablation
procedures
- The expected freedom from atrial fibrillation after one ablation procedure was 75% for isolation
plus electrograms and 45% for isolation alone.
- Successful pulmonary-vein isolation was achieved in 97% of all patients, with no significant
differences between groups.
- freedom from any documented episode of atrial fibrillation lasting longer than 30 seconds and
occurring after the performance of a single ablation procedure
- Adverse Events
- The most common adverse events were sedation-related complications
- Arteriovenous fistula or pseudoaneurysm at the access site
- Hematoma at the access site
- Fluid overload
- The most common adverse events were sedation-related complications
