About this study

Official title: Prospective Multicenter MANTA™ Vascular Closure Device Ultrasound Guided Closure Study

Demonstrate the safety of MANTA Vascular Closure Device (VCD) ultrasound (U/S) guided closure in patients undergoing elective TAVR procedures with planned percutaneous femoral arterial access.

Read the detailed description

The MANTA Vascular Closure Device is indicated for closure of femoral arterial access sites while reducing time to hemostasis following the use of 10-20F devices or sheaths (12-25F OD) in endovascular catheterization procedures.

This study is being conducted to demonstrate the safety of U/S guided closure with MANTA VCD following TAVR procedures utilizing large bore sheaths.

What is being measured

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

  1. Rate of Any Large Bore Access-site Related VARC-2 Major Vascular Complication

    adapted from VARC-2 Criteria

    Measured: within 30 days

Secondary outcomes (7)
  1. Time to Hemostasis

    The elapsed time between VCD deployment and first observed and confirmed arterial hemostasis.

    Measured: During the procedure

  2. Number of Patients With Technical Success

    Percutaneous vascular closure is obtained without the use of unplanned endovascular or surgical intervention.

    Measured: within 30 days

  3. Number of Subjects With Ambulation Success

    If a previously ambulatory patient (until day of TAVI) is able to ambulate for at least 20 feet/6 meters without re-bleeding.

    Measured: During procedure admission

  4. Time to Ambulation

    The elapsed time between VCD deployment and when ambulation is achieved.

    Measured: During procedure admission

  5. Treatment Success

    Time to Hemostasis ≤10 minutes and no VACR-2 Major complications

    Measured: within 30 days

  6. Procedure Time

    Elapsed time from initial skin break to time when the post-deployment angiogram is completed.

    Measured: During the procedure

  7. Rate of Any Large Bore Access-site Related VARC-2 Minor Vascular Complication

    adapted from VARC-2 Criteria

    Measured: within 30 days

Questions about this trial

What is this clinical trial studying?

A study testing MANTA Vascular Closure Device in people with Femoral Arteriotomy Closure, run by Essential Medical, Inc. at 6 sites in 2 countries.

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 4 inclusion and 20 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: stopped early, as of the sponsor's last update on 27 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States, Canada. 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?

Yes. Results are posted in the registry (first posted 27 Jul 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Rate of Any Large Bore Access-site Related VARC-2 Major Vascular Complication (time frame: within 30 days). 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 27 Jul 2023.
