Study summary

High blood pressure is a major risk factor for atrial fibrillation (AF), an irregular heart rhythm, and heart failure with preserved ejection fraction (HFpEF), a condition in which the heart becomes stiff and cannot relax properly. Both conditions can significantly affect quality of life and frequently occur together. In individuals with high blood pressure, increased activity of the nerves surrounding the kidneys can further elevate blood pressure and contribute to strain on the heart.

Renal denervation (RDN) is a procedure designed to lower blood pressure by reducing the activity of these nerves using a thin catheter and controlled energy. RDN has been shown to lower blood pressure safely in many patients; however, the potential benefits in individuals with concurrent AF and HFpEF remain uncertain.

This pilot study will be conducted in two phases. Phase 1 will assess the safety and feasibility of accessing the renal arteries and evaluating blood pressure responses to brief electrical stimulation of the renal nerves.

    Feasibility of Renal Artery Cannulation and Stimulation

    There is no control group, placebo group, or comparator arm. All enrolled participants undergo the same study procedure during their scheduled VT/PVC ablation.

    Procedure: Catheter-based renal artery electrical stimulation (as a feasibility assessment for renal denervation)

Interventions

  • ProcedureCatheter-based renal artery electrical stimulation (as a feasibility assessment for renal denervation)

    During a scheduled EP study ± VT/PVC ablation: Renal arteries are selectively visualized with angiography. The ablation catheter is advanced into each renal artery. Electrical stimulation is delivered: 10 V, 0.4 ms pulse width, 100 ms cycle length, 30 seconds per renal artery Blood pressure response is measured through arterial monitoring. A positive response is defined as ≥10 mmHg increase in systolic blood pressure.

What researchers measure

Primary outcomes

  1. Technical Success Rate of Renal Artery Cannulationn

    The proportion of patients in whom successful renal artery cannulation is achieved, as documented by the procedural operator. Technical success will be determined by successful catheter placement within the renal artery, allowing the planned procedure to proceed. Results will be reported as the number of successful cannulations divided by the total number of attempted cannulations, expressed as a percentage.

    Time frame: At the time of the procedure

  2. Successful Delivery of Electrical Stimulation

    The proportion of patients in whom electrical stimulation can be successfully delivered to the renal artery using the planned stimulation protocol.

    Time frame: At the time of the procedure

  3. Change in Invasive Arterial Blood Pressure During Renal Artery Stimulation

    The proportion of patients demonstrating a hypertensive response during renal artery stimulation, defined as an increase in systolic blood pressure of at least 10 mmHg compared with baseline, as measured using an arterial line

    Time frame: At the time of procedure

Timeline

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Aug 2026 (actual). Primary completion is estimated for Aug 2029, 36 months after the start.

Of 789 non-industry interventional studies with no phase under Atrial Fibrillation, half reached primary completion within 39 months of starting (the median), counting those still running; a quarter within 21 and three quarters within 59. This study's planned 36 months is close to that.

Counting every sponsor, half of 1,031 studies reached it within 34 months; a quarter within 18 and three quarters within 54.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
