Outcomes of convergent atrial fibrillation ablation with continuous rhythm monitoring
Omar M Lattouf, MD, PhD with patient
Outcomes of catheter ablation for persistent atrial fibrillation (PeAF) are suboptimal. The convergent procedure (CP) offers improved efficacy by combining endocardial and epicardial ablation. In a large, consecutive series of patients with predominantly PeAF, the CP was capable of reducing AF burden to very low levels (generally <5%), which appeared durable over time. Complication rates associated with the CP decreased significantly with the transition from transdiaphragmatic to sub-xiphoid surgical access. Future trials will be necessary to determine which patients are most likely to benefit from the convergent approach.
