About this study

Official title: Focal Pulsed Field Ablation for Paroxysmal Supraventricular Tachycardia: A Prospective, Multicenter, Single-Arm Study in Mainland China

The purpose of this study was to explore the safety and efficacy of pulsed field ablation(PFA) in the treatment of paroxysmal pupraventricular pachycardia(PSVT)with a contact force(CF)-sensing PFA Catheter

Read the detailed description

The primary efficacy endpoints were to evaluate the acute and 6-month follow-up success rate after PFA without the use of antiarrhythmic drugs . The primary safety endpoints were to assess the incidences of serious adverse events (SAEs) at the end of the procedure , discharge and during the 6-month follow-up period.

What is being measured

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

  1. Primary efficacy and safety endpoints

    The primary efficacy endpoints were to evaluate the acute and 6-month follow-up success rate after PFA without the use of antiarrhythmic drugs. The primary safety endpoints were to assess the incidences of SAEs at the end of the procedure and during the 6-month follow-up period.

    Measured: at end of the procedure, 1-month follow-up, 3-month follow-up, 6-month follow-up

Secondary outcomes (1)
  1. Interim analysis

    To assess immediate ablation ablation success at 6 months postoperatively, by Holter in single center.

    Measured: Refers to the postoperative phase after 6 months.

Questions about this trial

What is this clinical trial studying?

A study testing Pulsed Field Ablation Device and CF-Sensing Pulsed Field Ablation Catheter in people with Paroxysmal Supraventricular Tachycardia and Atrioventricular Nodal Reentrant 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 3 inclusion and 16 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: finished, as of the sponsor's last update on 28 May 2025. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Primary efficacy and safety endpoints (time frame: at end of the procedure, 1-month follow-up, 3-month follow-up, 6-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 28 May 2025.
