Key result
Advanced imaging and mapping tools may facilitate tailored ablation for non-paroxysmal AF.
Why the study?
Maintenance of sinus rhythm in non-paroxysmal AF remains challenging due to incomplete understanding of AF pathophysiology, and the clinical role of new imaging and mapping tools requires validation.
This review highlights the potential of advanced imaging and mapping tools to improve catheter ablation outcomes in non-paroxysmal AF, while noting the need for further validation.

Supports further investigation of advanced imaging for non-paroxysmal AF ablation; leaves open clinical adoption without randomized validation.
Despite intense research efforts, maintenance of sinus rhythm in patients with non-paroxysmal AF remains challenging with suboptimal outcomes. A major limitation to the success of current ablation-based treatments is that our understanding of AF pathophysiology is incomplete. Advances in imaging and mapping tools have been reported to improve ablation outcomes. However, the role of these new approaches on the clinical care of patients with AF remains to be validated and better understood before wide adoption can occur. This article reviews the current techniques of imaging and mapping that can be applied in the management of patients with non-paroxysmal AF with a focus on their relevance to catheter ablation. Future applications and opportunities for new knowledge are also discussed.

Ghannam et al. (2019) conducted a review in Non-paroxysmal Atrial Fibrillation. Imaging and mapping techniques (e.g., LGE-CMR, FIRM, ECGI) was evaluated. Advanced imaging and mapping tools, such as late-gadolinium enhanced MRI and spatiotemporal dispersion mapping, may facilitate tailored ablation approaches for non-paroxysmal atrial fibrillation.
