Nomograms developed for predicting the likelihood of sinus rhythm maintenance within 1 year following CA. (A) illustrates a radiomics nomogram, where each selected predictor, inclusive of the rad score, is assigned a score on the points scale situated at the top of the nomogram. The sum of these scores is then matched with the bottom scale, estimating the probability of sinus rhythm maintenance within 1 year after CA. As a comparison, (B) represents a clinical nomogram. This is designed utilizing the same set of clinical predictors as those in the radiomics nomogram, excluding the rad score. In line with the methodology of the radiomics nomogram, each predictor in the clinical nomogram is allocated a score on the points scale, and the cumulative scores serve to predict the likelihood of maintaining the sinus rhythm. AF, atrial fibrillation; PAF, paroxysmal atrial fibrillation; PeAF, persistent atrial fibrillation; LAAFV, left atrial appendage emptying flow velocity; PALS, peak atrial longitudinal strain; CA, catheter ablation.
