Key result
Non-invasive body surface mapping effectively identifies ablation targets to guide persistent AF ablation.
Why the study?
Interventional treatment of persistent and long-standing persistent AF remains challenging despite advances in catheter ablation, and non-invasive body surface mapping may improve guidance for ablation.

Noninvasive mapping may aid persistent AF ablation; leaves open whether it improves outcomes over standard approaches.
Atrial fibrillation (AF) is the most common rhythm disorder, and is strongly associated with thromboembolic events and heart failure. Over the past decade, catheter ablation of AF has advanced considerably with progressive improvement in success rates. However, interventional treatment is still challenging, especially for persistent and long-standing persistent AF. Recently, AF analysis using a non-invasive body surface mapping technique has been shown to identify localised reentrant and focal sources, which play an important role in driving and perpetuating AF. Non-invasive mapping-guided ablation has also been reported to be effective for persistent AF. In this review, we describe new clinical insights obtained from non-invasive mapping of persistent AF to guide catheter ablation.

Yamashita et al. (2015) conducted a review in Atrial fibrillation. Non-invasive body surface mapping-guided ablation was evaluated. Non-invasive body surface mapping identifies localized reentrant and focal sources and guides effective catheter ablation for persistent atrial fibrillation.
