evaluate the impact of various features in CMR on the mid-term/long-term success rate of rhythm control for paroxysmal atrial fibrillation/flutter .
* Atrial fibrillation/flutter are widely prevalent. * Reported antiarrhythmic drug efficacy to restore \& maintain sinus rhythm is 52% which is far from optimal. * On the other hand, 5-year arrhythmia-free survival after catheter ablation was previously reported to be 63%. * Therefore, there is a need for better characterization of the underlying atrial substrate, to improve treatment outcomes in terms of efficacy and safety

Recurence in patient with AF or flutter after pharmacological or interventional rythm control
* Non-invasive rhythm control arm: Predictors of atrial fibrillation recurrence within 6 months of cardioversion or the need for ≥2 cardioversions in the 1st year after initial cardioversion. * Ablation arm: Predictors of success rate (acute and mid term) of ablation on multivariable logistic regression analysis.
Time frame: Baseline
parameters for safe ablation
* Ablation arm: Predictors of esophageal thermal injury (ETI). * Arterial embolic events in both arms.
Time frame: Baseline
