The long-term effects of radiofrequency catheter ablation on quality of life in patients with typical atrial flutter are still unknown. This study included 100 consecutive patients with clinically documented typical atrial flutter. Subjective perception of quality of life was assessed by a semiquantitative questionnaire before, and 1 and 6 months after ablation. Ablation of typical atrial flutter was associated with a significant improvement in the general quality of life, frequency of significant symptoms, and symptoms during attacks. The frequency of hospital admission and emergency room visits, and number of antiarrhythmic drugs significantly decreased after ablation. Activity capacity significantly improved after ablation in patients with depressed left ventricular function. All improvements after ablation were maintained over 6-month follow-up. However, patients with atrial fibrillation compared with those without atrial fibrillation before ablation had less improvement in the general quality of life, frequency of significant symptoms, and symptoms during attacks (including palpitation, asthenia, effort, dyspnea, rest dyspnea, and dizziness). Furthermore, patients with atrial fibrillation before ablation needed more antiarrhythmic drugs, and had a higher frequency of hospital admission and emergent room visits at 6-month follow-up (all variables p <0.01). Multivariate analysis demonstrated that only the presence of atrial fibrillation before ablation could independently predict improvement in general quality of life (p = 0.03), frequency of significant symptoms (p = 0.03), symptoms during attacks (p = 0.04), and decrease in the consumption of health care resources including antiarrhythmic drugs (p = 0.01), hospital admission (p = 0.02), and emergency room visits (p = 0.02). Ablation of typical atrial flutter could significantly improve quality of life, but patients who had atrial flutter associated with atrial fibrillation before ablation had less improvement than those without atrial fibrillation.
