What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ablationDevice

    Also called Pulsed Field Ablation Device and CF-Sensing Pulsed Field Ablation Catheter

    All enrolled subjects will undergo radiofrequency or pulsed ablation for idiopathic ventricular arrhythmias using the investigational catheter.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Success rate of catheter ablation

    The primary efficacy endpoints were to evaluate the acute and 3-month follow-up success rate after ablation

    Measured: at end of the procedure, 1-month follow-up, 3-month follow-up

Secondary outcomes (1)
  1. Immediate success rate of ablation

    It is defined as the disappearance of the identical outflow tract ventricular arrhythmia that was present pre-ablation, with no inducible sustained identical outflow tract ventricular arrhythmia during 20 minutes of observation following pharmacological and/or electrophysiological stimulation.

    Measured: immediate ablation

Questions about this trial

What is this clinical trial studying?

A study testing ablation in people with Premature Ventricular Contractions and Ventricular Tachycardia, run by Shanghai MicroPort EP MedTech Co., Ltd. at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 31 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Success rate of catheter ablation (time frame: at end of the procedure, 1-month follow-up, 3-month follow-up). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Mar 2026.
