Key result
Cardiac CT and MRI characterize anatomy and arrhythmogenic substrate to guide AF ablation strategy.
Why the study?
Despite progress in technology and procedural strategy, catheter ablation for AF retains significant limitations with suboptimal outcomes, presenting an opportunity for multimodality imaging to improve safety and efficacy.
Cardiac computed tomography and magnetic resonance imaging can characterize anatomy and arrhythmogenic substrate to guide ablation strategy in patients with atrial fibrillation.
May support CT/MRI for AF ablation planning; leaves open need for prospective outcome trials.
Catheter ablation is increasingly utilized to treat patients with atrial fibrillation (AF). Despite progress in technology and procedural strategy, there remain significant limitations with suboptimal outcomes. The role of imaging has continued to evolve, and multimodality imaging now presents an important opportunity to make substantial progress in the safety and efficacy of ablation. In this review, we discuss the history of imaging in the ablation of AF with a specific focus on the ability of cardiac computed tomography and magnetic resonance imaging to characterize anatomy, arrhythmogenic substrate, and guide ablation strategy. We will review the progress that has been made and highlight many of the limitations as well as future directions for the field.

Markman et al. (2020) conducted a review in Atrial fibrillation. Cardiac imaging guidance (CT and MRI) was evaluated. Cardiac CT and MRI offer an important opportunity to characterize anatomy, arrhythmogenic substrate, and guide catheter ablation strategy for atrial fibrillation.
