CMR predictors of rhythm control in patient with AFibirilation/flutter
Brief summary
evaluate the impact of various features in CMR on the mid-term/long-term success rate of rhythm control for paroxysmal atrial fibrillation/flutter .
Detailed description
* 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

Eligibility
Inclusion criteria
* Age\>18 years. * Patients undergoing successful cardioversion (pharmacologic or electric) for atrial fibrillation/flutter, OR symptomatic patients with paroxysmal atrial fibrillation/flutter scheduled for trans-catheter ablation. * Index cardioversion OR Index ablation procedure.
Exclusion criteria
* LA thrombus on TEE or CMR. * Contraindications to CMR. * Contraindications to Gd-based contrast.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Recurence in patient with AF or flutter after pharmacological or interventional rythm control | Baseline | * 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| parameters for safe ablation | Baseline | * Ablation arm: Predictors of esophageal thermal injury (ETI). * Arterial embolic events in both arms. |
