Brief summary
The purpose of the ULTRA-HFIB Pilot is to determine the role of adjunctive renal denervation (RDN) in the prevention of Atrial Fibrillation (AF) recurrence in patients scheduled for an AF ablation procedure. Patients will be randomized to either i) AF ablation (Control) or ii) AF ablation + renal sympathetic denervation (Intervention).
Detailed description
The purpose of the ULTRA-HFIB Pilot is to determine the role of adjunctive renal denervation (RDN) in the prevention of AF recurrence in patients scheduled for an AF ablation procedure. Patients will be randomized to either i) AF ablation (Control) or ii) AF ablation + renal sympathetic denervation (Intervention). This is a prospective, controlled, single-blind, randomized trial. The pilot study will be conducted in up to 11 clinical sites in the United States and Europe.
Interventions
DEVICErenal denervation
Renal denervation using the Paradise renal denervation system - a dedicated RDN catheter that delivers a circumferential ring of ablative ultrasound energy
DEVICECatheter ablation
Catheter ablation - one of the most common procedures performed by Cardiac Electrophysiologists for atrial fibrillation

Masking description
Patients will be blinded until the 6 month visit, at which time they will be un-blinded prior to the follow up CT/MRI. The Clinical Events Committee and Echo Core Lab will remain blinded throughout the trial. In general, the CEC will be blinded to the treatment arms. However, once the nature of the event has been adjudicated, the blind will be broken for that individual patient as necessary to enable the CEC to determine relatedness to the study device.

Inclusion criteria
* Age ≥ 18 * Planned for a first-ever AF ablation procedure (paroxysmal or persistent); (prior to randomization, a technically successful AF ablation procedure, defined as involving pulmonary vein isolation, 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) * History of hypertension and either: * Documented history of SBP ≥ 160 or DBP ≥ 100 (Stage III), or * Receiving ≥ 1 antihypertensive medication * Willingness to adhere to study restrictions and comply with all post-procedural follow-up requirements
Exclusion criteria
(if any of the following are YES, subject is not eligible) * Long-standing persistent AF (\> 12 months) * Individual with valvular AF or AF due to a reversible cause * Prior left atrial catheter or surgical ablation for an atrial arrhythmia (before this index procedure) * Prior left atrial surgery (such as mitral valve surgery or surgical ASD repair) * 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 intra-procedural renal angiography). This includes: * Main renal artery diameter \< 3.0 mm or \> 8.0 mm * Main renal artery length \< 20 mm * Presence of renal artery stenosis of any origin ≥ 30% * Accessory arteries with diameter ≥ 2 mm and \< 3.0 mm * Calcification in renal arteries at locations where energy is to be delivered * Prior renal denervation procedure * Presence of abnormal kidney tumors * Renal artery aneurysm * Pre-existing renal stent or history of renal artery angioplasty * Pre-existing aortic stent or history of aortic aneurysm * Fibromuscular disease of the renal arteries * Iliac/femoral artery stenosis precluding insertion of the Paradise Catheter * Individual has an estimated glomerular filtration rate (eGFR) of less than 40mL/min/1.73m2 * Inability to undergo AF catheter ablation (e.g., presence of left atrial thrombus, contraindication to all anticoagulation) * Individual with known allergy to contrast medium not amenable to treatment * Life expectancy of \< 1 year for any medical condition * Individual has experienced a myocardial infarction, unstable angina, cerebrovascular accident, or heart failure admission within 3 months of screening visit * Documented history of chronic active inflammatory bowel disorders such as Crohn's disease or ulcerative colitis * Female participants who are pregnant or nursing * Individual has known secondary hypertension * Individual has a single functioning kidney (either congenitally or iatrogenically) * Individual has a known, unresolved history of drug use or alcohol dependency, lacks the ability to comprehend or follow instructions, or would be unlikely or unable to comply with study follow-up requirements * Patients concurrently enrolled in any other investigational drug or device trial that would interfere with the conduction of this trial
