Résumé

Patterns of atrial fibrillation (AF) recurrence post catheter ablation for persistent AF are not well described. This study aimed to describe the pattern of AF recurrence seen following catheter ablation for persistent AF (PsAF) and the implications for healthcare utilisation and quality of life. This was a post-hoc analysis of the CAPLA study, an international, multi-centre study that randomised patients with symptomatic PsAF to pulmonary vein isolation plus posterior wall isolation or pulmonary vein isolation alone. Patients underwent twice daily single lead ECG, implantable device monitoring or three monthly Holter monitoring. 154 of 333 (46.2%) patients (median age 67.3 years, 28% female) experienced AF recurrence at 12-month follow-up. Recurrence was paroxysmal in 97 (63%) patients and persistent in 57 (37%). Recurrence type did not differ between randomisation groups (p=0.508). Median AF burden was 27.4% in PsAF recurrence and 0.9% in paroxysmal AF (PAF) recurrence (p<0.001). Patients with PsAF recurrence had lower baseline left ventricular ejection fraction (PsAF 50% vs PAF 60%, p<0.001) and larger left atrial volume (PsAF 54.2±19.3 ml/m² vs PAF 44.8±11.6 ml/m², p=0.008). Healthcare utilisation was significantly higher in PsAF (45 patients [78.9%]) vs PAF recurrence (45 patients [46.4%], p<0.001) and lowest in those without recurrence (17 patients [9.5%], p<0.001). Patients without AF recurrence had greater improvements in quality of life as assessed by the Atrial Fibrillation Effect on Quality-of-Life (AFEQT) questionnaire (Δ33.3±25.2 points) compared to those with PAF (Δ24.0±25.0 points, p=0.012) or PsAF (Δ13.4±22.9 points, p<0.001) recurrence. AF recurrence is more often paroxysmal after catheter ablation for PsAF irrespective of ablation strategy. Recurrent PsAF was associated with higher AF burden, increased healthcare utilisation and antiarrhythmic drug use. The type of AF recurrence and AF burden may be considered important endpoints in clinical trials investigating ablation of PsAF.

BACKGROUND AND AIMS OBJECTIVE
Patterns of atrial fibrillation (AF) recurrence post catheter ablation for persistent AF are not well described. This study aimed to describe the pattern of AF recurrence seen following catheter ablation for persistent AF (PsAF) and the implications for healthcare utilisation and quality of life.
METHODS METHODS
This was a post-hoc analysis of the CAPLA study, an international, multi-centre study that randomised patients with symptomatic PsAF to pulmonary vein isolation plus posterior wall isolation or pulmonary vein isolation alone. Patients underwent twice daily single lead ECG, implantable device monitoring or three monthly Holter monitoring.
RESULTS RESULTS
154 of 333 (46.2%) patients (median age 67.3 years, 28% female) experienced AF recurrence at 12-month follow-up. Recurrence was paroxysmal in 97 (63%) patients and persistent in 57 (37%). Recurrence type did not differ between randomisation groups (p=0.508). Median AF burden was 27.4% in PsAF recurrence and 0.9% in paroxysmal AF (PAF) recurrence (p<0.001). Patients with PsAF recurrence had lower baseline left ventricular ejection fraction (PsAF 50% vs PAF 60%, p<0.001) and larger left atrial volume (PsAF 54.2±19.3 ml/m² vs PAF 44.8±11.6 ml/m², p=0.008). Healthcare utilisation was significantly higher in PsAF (45 patients [78.9%]) vs PAF recurrence (45 patients [46.4%], p<0.001) and lowest in those without recurrence (17 patients [9.5%], p<0.001). Patients without AF recurrence had greater improvements in quality of life as assessed by the Atrial Fibrillation Effect on Quality-of-Life (AFEQT) questionnaire (Δ33.3±25.2 points) compared to those with PAF (Δ24.0±25.0 points, p=0.012) or PsAF (Δ13.4±22.9 points, p<0.001) recurrence.
CONCLUSIONS CONCLUSIONS
AF recurrence is more often paroxysmal after catheter ablation for PsAF irrespective of ablation strategy. Recurrent PsAF was associated with higher AF burden, increased healthcare utilisation and antiarrhythmic drug use. The type of AF recurrence and AF burden may be considered important endpoints in clinical trials investigating ablation of PsAF.
