Previous studies have described that certain clinical characteristics such as age, obesity, the type of AF, and imaging-based factors, such as left atrial (LA) volume, mean density (calculated as the average of Hounsfield Units values in a certain región of interest), and volume of cardiac adipose tissue, may increase the risk of recurrence following pulmonary vein ablation.

Radiological variables included LA volume, mean density, and volume of epicardial, periatrial, and interatrial adipose tissue.
