Insights
Hybrid ablation (HA) offers improved rhythm control for persistent atrial fibrillation (AF) compared to catheter ablation (CA), reducing arrhythmias and medication needs. However, HA has a higher complication risk, requiring careful patient selection and experienced centers.
Area of Science:
- Cardiology
- Cardiac Surgery
- Electrophysiology
Background:
- Persistent, long-standing atrial fibrillation (AF) presents challenges for traditional endocardial catheter ablation (CA).
- Hybrid ablation (HA), combining thoracoscopic and endocardial approaches, aims to overcome these limitations.
- This review evaluates HA versus CA for rhythm control and safety in persistent AF patients.
Purpose of the Study:
- To compare the efficacy and safety of hybrid ablation (HA) versus endocardial catheter ablation (CA).
- To assess rhythm-control outcomes, including freedom from AF and arrhythmia recurrence.
- To evaluate procedural safety and complication rates associated with both HA and CA.
Main Methods:
- A systematic review of randomized controlled trials and observational studies comparing HA and CA in adults with non-paroxysmal AF.
- Searches conducted in PubMed, Embase, and Cochrane databases.
- Primary outcomes included freedom from AF, atrial arrhythmia, antiarrhythmic drug use, recurrence, and repeat ablation.
Main Results:
- Eight studies involving 907 patients were analyzed (478 HA, 429 CA).
- HA did not significantly reduce AF or arrhythmia recurrence compared to CA.
- HA significantly reduced other atrial arrhythmias, antiarrhythmic drug use, and repeat ablation rates, but increased complication risk.
Conclusions:
- Hybrid ablation provides superior rhythm control for persistent AF compared to catheter ablation.
- Despite greater procedural complexity and a higher risk of complications, HA is an effective strategy in selected patients.
- Experienced multidisciplinary programs demonstrate comparable safety profiles for HA and CA.
Background:
Hybrid ablation (HA) addresses the limitations of endocardial catheter ablation (CA) in patients with persistent, long-standing atrial fibrillation (AF). This review compares hybrid thoracoscopic-endocardial ablation with endocardial CA in this population to evaluate rhythm-control outcomes and procedural safety.
Methods:
Randomized controlled trials and observational studies comparing HA with CA in adults with non-paroxysmal AF were identified through searches of PubMed, Embase, and Cochrane databases (November 2025). The review was registered with PROSPERO (CRD42024600526). Primary outcomes included freedom from AF, any atrial arrhythmia, use of antiarrhythmic drugs (AADs), arrhythmia recurrence, and repeat ablation.
Results:
Eight studies (907 patients: 478 HA; 429 CA) were included. Compared to CA, HA did not significantly reduce AF (OR 2.38; 95% CI 0.66-8.65) or arrhythmia recurrence (OR 1.66; 95% CI 0.31-9.06). HA significantly reduced any atrial arrhythmia (OR 3.36; 95% CI 2.16-5.23) and AADs (OR 3.25; 95% CI 2.20-4.82) and repeat ablation rates (OR 0.28; 95% CI 0.09-0.90). HA increased risk of significant complications (OR 2.73; 95% CI 1.18-6.27) despite a significantly shorter fluoroscopy time. Heterogeneity reflected variations in lesion sets, epicardial energy modality, surgical access, timing, and comparator CA strategies. Recent randomized trials show comparable safety profiles for HA and CA when hybrid procedures are performed in experienced multidisciplinary programs.
Conclusion:
HA offers better rhythm control than CA in persistent AF, although it involves greater procedural complexity. In appropriately selected patients and institutions with established hybrid expertise, HA is an effective rhythm-control strategy that yields clinically significant benefits.
