Assessing AThrough Radiofrequency Transseptal Puncture System for Left Atrial Access

April 23, 2024 updated by: Hangzhou NOYA MedTech Co. Ltm.

A Prospective, Multicenter, Randomized Controlled, Non-inferiority Clinical Study Evaluating the Safety and Efficacy of the AThrough Radiofrequency Transseptal Puncture System in Atrial Septal Puncture.

This study is a prospective, multicenter, randomized controlled trial with a non-inferiority design. Participants are patients scheduled for atrial septal puncture. After signing informed consent, subjects will be randomly assigned to either the radiofrequency transseptal puncture system group (referred to as the trial group) or the traditional mechanical transseptal puncture system group (referred to as the control group). All participants will undergo immediate postoperative and discharge clinical follow-ups.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Patient age ≥ 18 years;
  2. Subjects scheduled to undergo cardiology interventional treatment via the transseptal puncture route;
  3. Subjects have been informed about the nature of the study, understand the purpose of the clinical trial, and voluntarily participate and sign the informed consent form.

Exclusion Criteria:

  1. Echocardiogram indicates the presence of intracardiac masses, thrombi, or vegetations; left atrial myxoma;
  2. Subjects with an atrial septal defect occluder or atrial septal patch implant;

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Transseptal puncture success rate.
Time Frame: Intraprocedural assessment
Defined as successfully completing the puncture in the atrial septum and establishing a pathway from the right atrium to the left atrium (with the sheath entering the left atrium) using the transseptal puncture system
Intraprocedural assessment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Initial transseptal puncture success rate.
Time Frame: Intraprocedural assessment
Defined as the period from the introduction of the transseptal puncture system into the femoral vein to the entry of transseptal sheath into the left atrium.
Intraprocedural assessment
Time required to successfully complete the transseptal puncture.
Time Frame: Intraprocedural assessment
Defined as the time from when the transseptal puncture system is introduced into the femoral vein to when the transseptal sheath enters the left atrium.
Intraprocedural assessment
Number of attempts needed to successfully complete the transseptal puncture.
Time Frame: Intraprocedural assessment
During the transseptal puncture process, if the transseptal puncture system needs to be readjusted upwards and repositioned for oval fossa puncture, each readjustment should count as an additional attempt.
Intraprocedural assessment
Ratio of atrial septal puncture failures that cross over to the opposite group.
Time Frame: Intraprocedural assessment
Ratio of atrial septal puncture failures that cross over to the opposite group;
Intraprocedural assessment
