Dual Energy Focal Ablation of Premature Ventricular Complexes (DUAL-PVC)

8 de noviembre de 2026 actualizado por: Konstantinos Siontis

Dual Energy (RF/PF) Focal Ablation of Premature Ventricular Complexes: the DUAL-PVC Prospective Clinical Trial

The purpose of this research is to understand whether a dual-energy catheter ablation system that uses radiofrequency (RF) and pulsed-field (PF) energy can safely and effectively treat premature ventricular contractions (PVCs).

Descripción

Inclusion Criteria:

  • ≥10% burden of the target PVC on ambulatory rhythm monitoring within 3 months prior to enrollment. The qualifying ambulatory monitor may be of any duration (1-30 days) per standard of care and may be distinct from the baseline 12-lead Holter required within 30 days before ablation

  • Guideline-supported indication for first-time or redo catheter ablation of PVCs at the judgment of the electrophysiologist. Specifically:

    • Patients with symptomatic PVCs for whom antiarrhythmic medications are ineffective, not tolerated, or not the patient's preference.
    • Suspected or confirmed PVC-induced cardiomyopathy
    • Enrollment of patients requiring a redo procedure will be capped at 30% of planned enrollment (n=18) if the target PVC is the same or similar to that targeted in previous procedure(s), per review of the study investigator
  • Patients with and without known structural heart disease are eligible

  • Ability to undergo study-directed cardiac MRI pre- and post-procedure

  • Ability to undergo study-directed post-ablation coronary CT angiography

  • Ability to provide written informed consent

Exclusion Criteria:

  • LVEF <35%
  • NYHA class IV
  • Presence of multifocal PVCs (>=3 distinct morphologies) on available pre-baseline standard-of-care ambulatory monitor and ECG tracings per the review of the study team.
  • PVCs attributable to a reversible or non-cardiac cause (e.g., electrolyte imbalance or active thyroid disease).
  • History of sustained VT or VF.
  • Current or recent (<4 weeks) decompensated heart failure.
  • Active systemic infection.
  • Contraindication to LGE-MRI or contrast CT.
  • Known allergy to iodinated contrast dye that cannot be adequately managed with pre-medication protocol.
  • Thrombocytopenia (platelet count <50,000/mm³) or known coagulopathy.
  • Contraindication to systemic anticoagulation.
  • Severe valvular disease requiring future intervention.
  • Mechanical valve prosthesis.
  • Pregnancy.
  • Recent acute coronary syndrome (<6 months).
  • Un-revascularized coronary artery disease.
  • Presence of left ventricular assist device (LVAD) or transplanted heart.
  • Presence of intracardiac thrombus.
  • Current use of inotropes.
  • Recent stroke or TIA (<6 months).
  • Presence of a systemic illness likely to limit survival to <1 year.
  • Patient enrollment in other clinical study that could conflict with the current investigation.

Armas e Intervenciones

Grupo de participantes/brazo
Intervención / Tratamiento
Experimental: RF-PF Sequential Ablation

Participants are assigned to receive radiofrequency (RF) followed by pulsed-field (PF) at each selected treatment site. For each PF treatment, 24 PF bursts are delivered. Up to three stacked lesions may be performed at the same location.

The THERMOCOOL SMARTTOUCH™ SF Bi-Directional Navigation Catheter is an irrigated, contact-force-sensing catheter used to map the heart and deliver radiofrequency (RF) or pulsed-field (PF) energy to selected treatment sites. The catheter is connected to the TRUPULSE™ Generator, which provides both energy types, and to the nGEN™ Pump, which controls saline irrigation. The system is used with the CARTO™ 3 electroanatomic mapping system and workstation with the VISITAG SURPOINT™ Module to display heart anatomy, catheter location, catheter-to-tissue contact, and treatment information during the procedure.

Experimental: PF-Only Ablation

Participants are assigned to receive pulsed-field (PF) alone at each selected treatment site. For each PF treatment, 24 PF bursts are delivered. Up to three stacked lesions may be performed at the same location.

Periodo de tiempo
Number of Participants With Successful Delivery of Ablation Lesions Using the Dual-Energy THERMOCOOL SMARTTOUCH SF Catheter With the TRUPULSE Generator
Periodo de tiempo: During the index ablation procedure

Feasibility is defined as successful delivery of ablation energy at the targeted premature ventricular complex (PVC) site. Delivery counts as successful only if there is no study device deficiency or malfunction that prevents energy delivery, and no need to convert to a bailout ablation approach.

During the index ablation procedure

Periodo de tiempo
Acute procedural success
Periodo de tiempo: End of the ablation procedure

Number of participants with elimination of the target premature ventricular contraction by the end of the procedure.

1 month, 6 months
Change in Short Form Health Survey (SF-36) score
Periodo de tiempo: Baseline, 1 month, 6 months

The 36-Item Short Form Health Survey (SF-36) is a participant-reported questionnaire that assesses health-related quality of life across eight domains: physical functioning, role limitations due to physical health, bodily pain, general health, vitality, social functioning, role limitations due to emotional problems, and mental health. Total scores range from 0 to 100. Higher scores indicate better health status.

Baseline, 1 month, 6 months
Change in EQ-5D score
Periodo de tiempo: Baseline, 1 month, 6 months

The EQ-5D is a participant-reported measure of health-related quality of life covering five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Responses across the five dimensions define the participant's health state. Higher scores indicate better health.

Baseline, 1 month, 6 months
