ULTRA-HFIB-Redo: Ultrasound-based Renal Sympathetic Denervation vs Control in Redo Ablation Patients

Inclusion Criteria: * Age ≥ 18; * Planned for a redo AF ablation procedure (paroxysmal or persistent); (prior to randomization, a technically successful AF ablation procedure, defined as successful pulmonary vein isolation, if needed, as well as bidirectional block of any attempted anatomic lesion sets such as cavotricuspid isthmus line, roofline, mitral line and superior vena cava isolation, must have been completed). Note: the clinical recurrences must primarily be atrial fibrillation, and not atrial flutter/tachycardia (that is, a prospective patient may have a AFL/AT recurrences, but AF must be the dominant recurrent rhythm.) * History of hypertension and either: * Documented history of SBP≥160 or DBP≥100, or; * Receiving ≥1 antihypertensive medication; * Willingness to adhere to study restrictions and comply with all post-procedural follow-up requirements Exclusion Criteria: * Long-standing persistent AF (\>12 months); \>3 prior atrial fibrillation ablations (lifetime); AF ablation within 3 months of enrollment; extensive scar in left atrium. * Individual with valvular AF or AF due to a reversible cause * Prior treatment with other devices for hypertension including but not limited to ROX Coupler, Mobius stent, and/or the CVRx barostimulator device. * NYHA class IV congestive heart failure; * Individual has renal artery anatomy that is ineligible for treatment (as determined by renal angiography); * Main renal artery diameter \<3mm or \>8.0 mm * Main renal t…
