Key result
LGE-CMR assessment of left atrial fibrosis predicts AF recurrence after catheter ablation.
Why the study?
The role of atrial fibrosis assessed by cardiac MRI in predicting atrial fibrillation recurrence after radiofrequency ablation remains to be summarized.
Does LGE-CMR assessment of atrial fibrosis predict recurrence of atrial fibrillation after catheter ablation?
Does LGE-CMR assessment of atrial fibrosis predict recurrence of atrial fibrillation after catheter ablation?
Assessing atrial fibrosis with LGE-CMR before catheter ablation may improve patient selection and procedural success in atrial fibrillation.
May refine post-ablation AF recurrence risk via LGE-CMR fibrosis assessment; leaves open prospective validation before practice change.
Atrial fibrillation (AF) is the most frequent cardiac arrhythmia increasing the risk of stroke and mortality from heart failure. Magnetic resonance imaging was used by several authors for assessment of atrial fibrosis and to predict the rate of recurrence following AF ablation. The aim of this manuscript was to summarize the new data in the literature regarding the role of atrial fibrosis in AF imaging and the role of cardiac fibrosis in predicting AF recurrence after radio-frequency ablation.

Kovács et al. (2016) conducted a review in Atrial fibrillation. Late gadolinium-enhanced cardiac magnetic resonance (LGE-CMR) was evaluated. Assessment of left atrial fibrosis using late gadolinium-enhanced cardiac magnetic resonance imaging predicts the recurrence of atrial fibrillation following catheter ablation.
