Why the study?
Does radiofrequency catheter ablation alter the perception of atrial fibrillation in patients with highly symptomatic AF?
Does radiofrequency catheter ablation alter the perception of atrial fibrillation in patients with highly symptomatic AF?
Symptom-based follow-up after AF ablation overestimates success rates due to an increase in asymptomatic episodes, necessitating objective long-term monitoring.
Answers are grounded in this paper and cite their sources.
May warrant objective monitoring to gauge ablation outcomes accurately; leaves open standardized trial endpoints.
Even in patients presenting with highly symptomatic AF, asymptomatic episodes may occur and significantly increase after catheter ablation. A symptom-only-based follow-up would substantially overestimate the success rate. Objective measures such as long-term Holter monitoring are needed to identify asymptomatic AF recurrences after ablation.
