MB-LATER score as a useful tool for prediction of arrhythmia recurrence after radiofrequency catheter ablation of atrial fibrillation: Clinical application

Atrial fibrillation (AF) is most frequent sustained cardiac arrhythmia in general population. It is well established that crucial task for management of these patients is prevention of AF‐related complications. One of the most important management strategies represents catheter ablation in order to reduce AF burden, to achieve symptomatic and functional improvement, and in some patient (e.g. heart failure) to reduce overall mortality. Several prognostic scores were developed for AF recurrence prediction after catheter ablation of AF. Role of these scores might be better optimization of long-term follow-up and deciding on discontinuation of oral anticoagulant therapy and stopping of antiarrhythmic drugs after the procedure, thus identification of patients at risk for arrhythmia recurrence may be extremely important. Numerous clinical factors are associated with arrhythmia recurrence and some of those are used for developing rhythm-outcome specific scores. MB-LATER score was retrospectively derived for prediction of arrhythmia recurrence after catheter ablation of AF, and in this article, we are going to discuss its utilization in clinical practice.
