What is the likelihood of success from atrial fibrillation ablation?
Single Procedure Success Rate Estimates Clinical Benefit: – 80-90% of patients are improved after a single procedure – 60-70% No atrial fibrillation seen, off antiarrhythmic drugs – >90% Atrial fibrillation symptoms markedly improved Frequency much less or now easily controlled by drugs * Some patients (persistent atrial fibrillation, more significant associated heart disease) have more difficult to treat variants of atrial fibrillation and we may have lower success rates. Repeat Procedures: Can be considered if results of first procedure unsatisfactory and will improve the overall success rates. This may be required in up to 20% of patients to cure their atrial fibrillation. Stopping Warfarin: Considered on case-by-case basis depending on patients risk of stroke.
