Insights
Hybrid ablation significantly reduces atrial fibrillation recurrence and repeat procedures compared to endocardial ablation alone in persistent AF patients. Further trials are needed to confirm these findings.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Devices
Background:
- Persistent atrial fibrillation (AF) management remains challenging, with variable outcomes after endocardial catheter ablation.
- Hybrid epicardial-endocardial ablation has emerged as a promising alternative for refractory cases.
Purpose of the Study:
- To compare the effectiveness of hybrid ablation versus endocardial ablation alone in patients with persistent and long-standing persistent AF.
- To evaluate recurrence rates and need for repeat procedures in both ablation strategies.
Main Methods:
- A study involving 133 patients with persistent AF, divided into endocardial ablation alone (n=69) and hybrid epicardial-endocardial ablation (n=64) groups.
- Patients were followed for a median of 16 months, with recurrence defined as any arrhythmia post-blanking period.
Main Results:
- The hybrid group demonstrated significantly lower recurrence rates (37% vs. 58%) and repeat ablations (9% vs. 26%) compared to the endocardial group.
- AF-free survival was higher in the hybrid group (72% vs. 51%).
- Despite longer AF duration and more prior ablations in the hybrid group, outcomes were superior.
Conclusions:
- Hybrid ablation is associated with reduced AF recurrence and fewer re-do ablations in persistent AF patients.
- These findings suggest hybrid ablation as a more effective strategy for selected patients.
- Large-scale randomized trials are warranted to validate these promising results.
Objectives:
The outcomes of hybrid ablation versus endocardial catheter ablation alone were evaluated in patients with persistent and long-standing persistent atrial fibrillation (AF).
Background:
Variable outcomes exist following endocardial catheter ablation in medically refractory patients with persistent AF. A hybrid epicardial-endocardial approach has emerged as an alternative to endocardial ablation.
Methods:
In 133 consecutive patients, 69 received endocardial ablation alone (pulmonary vein isolation and radiofrequency catheter ablation [endo group]) and 64 received endocardial catheter ablation and epicardial ablation (hybrid group). Recurrence was defined as any arrhythmia following the 3-month blanking period.
Results:
Patients were followed for a median of 16 months. The hybrid and endo groups were similar in age (61 ± 10 years vs. 62 ± 8 years), body mass index (35 ± 6 kg/m2 vs. 35 ± 7 kg/m2), CHA2D2-VASc score (2 ± 1 vs. 2 ± 1), and ejection fraction (54 ± 11% vs. 53 ± 8%). The hybrid group had longer AF duration (median [interquartile range (IQR)] (12 months [IQR: 8 to 28 months] vs. 7 months [IQR: 5 to 12 months]; p < 0.001) and more previous ablations (58% vs. 25%; p < 0.001). Both groups had similar antiarrhythmic drug use at follow-up (55% vs. 48%). The hybrid group was less likely to have recurrence (37% vs. 58%; p = 0.013) and repeat ablation (9% vs. 26%; p = 0.012), and had an AF-free survival of 72% versus 51% (p = 0.01).
Conclusions:
Among patients with persistent AF, hybrid ablation is associated with less AF recurrence and fewer re-do ablations. Prospective large-scale randomized trials are needed to validate these results.
