Validation of the predictive value of the Left Atrial Sphericity for AF recurrence of atrial fibrillation after a pulmonary vein ablation procedure in an external, multicenter cohort.~In total, 9 centers will include consecutive patients who underwent AF ablation from january to december 2013 in whom a 3D-imaging of the left atrium (Cardiac CT or MRA) was acquired prior to the procedure and when procedural/follow-up data was prospectively collected.
This is a Multicenter Observational 1-year retrospective cohort study evaluating the predictive value of the Left Atrial Sphericity on the recurrence rate of atrial fibrillation after pulmonary vein ablation procedure.~Inclusion of consecutive patients undergoing AF ablation during 2013 in whom a 3D-imaging of the left atrium (Cardiac CT or MRA) was acquired prior to the procedure and when procedural/follow-up data was prospectively collected.
