Left atrial epicardial adipose tissue volume quantification by CMR aids identification of patients at low risk for left atrial cardiomyopathy

The pre-procedural identification of a low risk of atrial cardiomyopathy is important to select patients for single-shot catheter ablation. LA-EATVi proved to be of additive value to known risk factors for the prediction of LVZ in a combined prediction model. Patients not considered low risk could be offered an electroanatomic atrial mapping for LVZ detection with the possibility of an LVZ-based radiofrequency ablation approach. Individualized matching of patient and ablation technique using an LVZ prediction model might lead to improved ablation outcomes.
