Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - Left atrial ablation
Treatment: Drugs - Rate or Rhythm Control Therapy

Active comparator: Left Atrial Ablation - Pulmonary vein isolation using a circumferential ablative approach in the left atrium. Ablation may be performed using circular mapping catheter-guided ablation, antral isolation using a circular guided approach, or wide area circumferential ablation.

Active comparator: Rate or Rhythm Control Therapy - Current state-of-the-art drug therapy for atrial fibrillation (rate control or rhythm control). Treating physicians will be encouraged to follow the American College of Cardiology / American Heart Association / European Society of Cardiology Atrial Fibrillation Guidelines with regard to drug therapy for atrial fibrillation. The specific choice of rate control versus rhythm control drug therapy and the specific drugs to be used will ultimately be left to the discretion of the treating physician.

Eligibility
Key inclusion criteria
* Over the preceding 6 months have:

1. =2 paroxysmal (electrocardiographic documentation of at least 1) atrial fibrillation (AF) episodes lasting =1 hour in duration: (that terminate spontaneously within 7 days or cardioversion is performed within 48h of AF onset): or
2. electrocardiographic documentation of 1 persistent AF episode: (sustained for =7 days or cardioversion is performed more than 48h after AF onset): or
3. electrocardiographic documentation of 1 longstanding persistent AF episode: (continuous AF of duration >1 year).
* Warrant active therapy (within the past 3 months) beyond simple ongoing observation
* Be eligible for catheter ablation and =2 sequential rhythm control and/or =2 rate control drugs.
* Be =65 yrs of age, or <65 yrs with one or more of the following risk factors for stroke: Hypertension (treated and/or defined as a blood pressure >140/90 mmHg) [90], Diabetes (treated and/or defined as a fasting glucose =126 mg/dl) [91], Congestive heart failure (including systolic or diastolic heart failure), Prior stroke, transient ischemic attack or systemic emboli, Atherosclerotic vascular disease (previous myocardial infarction (MI), peripheral arterial disease or aortic plaque), left atrial (LA) size >5.0 cm (or volume index =40 cc/m2), or ejection fraction (EF) =35.
* Have the capacity to understand and sign an informed consent form.
* Be =18 years of age.

* NOTE- Subjects <65 yrs of age whose only risk factor is hypertension must have a second risk factor or left ventricular (LV) hypertrophy to qualify.Patients receiving new drug therapy initiated within the previous 3 months may continue that therapy if randomized to the drug therapy arm. Patients may have documented atrial flutter in addition to atrial fibrillation and remain eligible for enrollment.

* Patients who have failed >2 membrane active anti-arrhythmic drugs at a therapeutic dose due to inefficacy or side effects (Table 5.2.2)
* An efficacy failure of full dose amiodarone treatment >8 weeks duration at any time
* Reversible causes of AF including thyroid disorders, acute alcohol intoxication, recent major surgical procedures, or trauma
* Recent cardiac events including MI, percutaneous intervention (PCI), or valve or bypass surgery in the preceding 3 months
* Hypertrophic obstructive cardiomyopathy (outflow track)
* Class IV angina or Class IV congestive heart failure (CHF) (including past or planned heart transplantation)
* Other arrhythmias mandating anti-arrhythmic drug therapy (i.e. ventricular tachycardia (VT), ventricular fibrillation (VF))
* Heritable arrhythmias or increased risk for torsade de pointes with class I or III drugs
* Prior LA catheter ablation with the intention of treating AF
* Prior surgical interventions for AF such as the MAZE procedure
* Prior AV nodal ablation
* Patients with other arrhythmias requiring ablative therapy
* Contraindication to appropriate anti-coagulation therapy
* Renal failure requiring dialysis
* Medical conditions limiting expected survival to <1 year
* Women of childbearing potential (unless post-menopausal or surgically sterile)
* Participation in any other clinical mortality trial (Participation in other non-mortality trials should be reviewed with the clinical trial management center)
* Unable to give informed consent

* NOTE- Prior ablation of the cavo-tricuspid isthmus alone is not an exclusion if the patient develops subsequent recurrent AF. Planned atrial flutter ablation in combination with the left atrial ablation is not an exclusion.
