Key result
Advanced imaging modalities, including intracardiac echocardiography, cardiac MRI, and CT, show promise in improving atrial fibrillation ablation outcomes by reducing radiation and procedural times.
Why the study?
Available data on procedural utility and the reduction in AF recurrence rates associated with imaging modalities in AF ablation remain mixed.
Advanced imaging modalities in AF ablation, including intracardiac echocardiography and image integration with CT/MRI, can reduce radiation exposure and procedural times, but further randomized trials are needed to confirm improvements in procedural success and AF recurrence.

Since the introduction of atrial fibrillation (AF) ablation in the 1990s, the procedure has continuously evolved, with gradual improvements in outcomes and safety. Recent technological advancements include the introduction of contact force catheters and high-resolution electroanatomical mapping systems, while imaging modalities including transesophageal echocardiography and fluoroscopy have become integral parts of AF ablation procedures. Further, intraprocedural intracardiac echocardiography and the integration of cardiac magnetic resonance and computed tomography images with electroanatomical mapping have shown promise to improve procedural outcomes by reducing radiation exposure and procedural times. However, available data on procedural utility and the reduction in AF recurrence rates associated with these modalities are mixed. This review therefore aims to discuss the current common imaging modalities used in AF ablation and their potential impact on outcomes. In particular, imaging is discussed with respect to the important information it offers before, during, and after the procedure. Perspectives on the future of imaging in AF ablation are also shared.
