METHODS AND RESULTS: In 83 patients undergoing catheter ablation for AF, CE-CMR was used to assess LA volume, sphericity, and fibrosis. There was a significant correlation between LA volume and sphericity (R = 0.535, P < 0.001) and between LA volume and fibrosis (R = 0.241, P = 0.029). Multivariate analyses demonstrated that LA volume was the strongest independent predictor of AF recurrence after catheter ablation (1.019, P = 0.018). CONCLUSION: LA volume, sphericity, and fibrosis were closely related; however, LA volume was the strongest predictor of AF recurrence after catheter ablation.23 p.application/pdfeng(c) Wiley, 2018Fibril·lació auricularArrítmiaRessonància magnèticaAtrial fibrillationArrhythmiaMagnetic resonanceinfo:eu-repo/semantics/article6802042019-11-26info:eu-repo/semantics/openAccess
