Opinion statement

Ablation therapy is widely used for treatment of drug-resistant atrial fibrillation (AF). Ablation success for AF, however, is relatively low, often requiring repeated procedures for long-term suppression of the arrhythmia. Utilization of imaging techniques that visualize cardiac anatomy, function, and tissue characteristics may improve ablation results. Compared to other imaging modalities, cardiac magnetic resonance (CMR) has several advantages, including the lack of ionizing radiation and unsurpassed soft tissue resolution. Chamber morphology images can be registered onto electroanatomic maps acquired during the procedure, thus improving procedural safety and efficacy. In addition, the ability of CMR to characterize myocardial tissues may optimize patient selection for ablation and thromboembolic risk stratification. Post-procedure CMR can be used to detect potential complications, and with improved resolution, it has the potential to assess the integrity of ablation lesions. In this paper we will review the role of CMR in the pre-ablation diagnostic workup of AF patients as well as during and after catheter ablation.

This study reported a novel method to quantifiy a normalized measure of LA fibrosis, the image intensity ratio (IRR). The local IRR is defined as LA myocardial intensity devided by the mean LA blood pool image intensity. This metric is closely associated with intracardiac voltage, a surogate for atrial fibrosis.

In addition, LA T1 mapping was strongly associated with intracardiac voltage.

There was a significant relationship between the number of veins encircled by delayed enhancement and clinical success. In addition, an increase in postablation scar of the posterior and septal wall was associated with reduced recurrences rates.
