St. George's Hospital, London
120 participants
Jun 25, 2022
INTERVENTIONAL
Conditions
Summary
A randomised controlled trial to assess the efficacy of staged hybrid ablation when compared with standard catheter ablation in patients with non-paroxysmal atrial fibrillation (AF) and Heart Failure
Eligibility
Inclusion Criteria5
- Age ≥ 18 years
- Persistent or Long-standing Persistent AF
- Dilated left atrium (at least moderately dilated)
- Suitable for either procedure
- LVEF \< 50%
Exclusion Criteria12
- Not yet optimised from a medical or lifestyle perspective for AF or heart failure
- Unable to provide written consent
- Previous open-heart surgery
- Active infection, oesophageal ulcer stricture or oesophageal varices
- Prior catheter ablation of atrial fibrillation (prior ablation for atrial flutter / supraventricular tachycardia or ventricular arrhythmia acceptable)
- Contraindication to anticoagulation, or active thrombus in the left atrium despite therapeutic anticoagulation
- Severe valvular heart disease
- Unstable coronary artery disease
- Uncontrolled ventricular arrhythmia
- Heart attack or stroke within the last 90 days
- Pregnant, breastfeeding, or women of childbearing age who plan to get pregnant within six months
- Severe concomitant condition or presence of an implanted device that would preclude the patient from undergoing trial procedures
Interventions
Minimally-invasive epicardial ablation +/- left atrial appendage exclusion using an epicardial clip, combined with endocardial radiofrequency catheter ablation
Standard percutaneous endocardial catheter ablation of atrial fibrillation
