About this study

This is a prospective, single-arm, multi-center, open study to assess the clinical performance and safety of the Point-Guard CEPD during a TAVR procedure.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • The patient is ≥18 years of age;
  • The patient meets indications for Transcatheter Aortic Valve Replacement (TAVR);
  • The patient is willing to comply with protocol-specified follow-up evaluations;
  • The patient has been informed of the nature of the study, agrees to its provisions, and has provided written informed consent, approved by the appropriate Institutional Review Board or Ethics Committee.

Exclusion criteria

  • TAVR conducted via other than transfemoral access (subclavian, axillar, transapical, transaortic, carotid or transcaval).
  • Anatomy that precludes safe delivery and retrieval of the investigational device.
  • Current or planned treatment with any investigational drug or investigational device during the study enrollment or follow-up period.
  • Cardiovascular surgical or interventional procedure 10 days prior or planned during the TAVR procedure or during the 30-day study follow-up.
  • Patients with uncontrolled bleeding disorders.
  • Patients who are pregnant, as confirmed by a positive pregnancy test.

General Exclusion Criteria

  • TAVR conducted via other than transfemoral access (subclavian, axillar, transapical, transaortic, carotid or transcaval).
  • Anatomy that precludes safe delivery and retrieval of the investigational device.
  • Current or planned treatment with any investigational drug or investigational device during the study enrollment or follow-up period.
  • Cardiovascular surgical or interventional procedure 10 days prior or planned during the TAVR procedure or during the 30-day study follow-up.
  • Patients with uncontrolled bleeding disorders.
  • Patients who are pregnant, as confirmed by a positive pregnancy test.

Magnetic resonance imaging exclusion criteria:

  • Body Mass Index (BMI) and/or total body weight precluding imaging in scanner.
  • Contraindications to MRI (subjects with any implantable temporary or permanent pacemaker or defibrillator, metal implants in field of view, metallic fragments, clips, or devices in the brain or eye before TAVR procedure).
  • High risk of complete AV block after TAVR, with the need of permanent pacemaker (e.g., subjects with pre-existing bifascicular block or complete right bundle branch block plus any degree of AV block).
  • Existing or planned implantation of a pacemaker or defibrillator implantation within the first 3 days after TAVR.
  • Claustrophobia precluding MRI scanning.

Treatment and study plan

Cerebral Embolic Protection

Device

Use of Transverse Medical Inc. Point-Guard CEP device.

Primary outcomes

  1. Primary Endpoint

    Time frame: From beginning of TAVI procedure to end.

    Technical success, defined as successful deployment, positioning and retrieval per the Instructions For Use (IFU), with minimal device interference, and as outlined below:

    • Deployment of the Point-Guard filter unit from the Delivery sheath into the aortic arch;
    • Positioning of the Point-Guard device within the aortic arch;
    • Retrieving and removing the Point-Guard device intact;
    • Minimal device interference (operator assessed).
  2. Primary Safety Endpoints

    Time frame: Beginning of TAVI procedure to 30 days post-procedure.

    • Primary Safety Endpoint: TAVR procedure complications associated with the delivery, positioning, and removal of the test device.
    • Primary Safety Endpoint: MACCE (all death, all stroke, and acute kidney injury class 3) within 72 hours or discharge, whatever occurs first and at 30 days.

Other outcomes

  1. Observational Endpoints

    Time frame: 24 hours pre-procedure to 24 hours post-procedure

    • Reduction in Median Total New Lesion Volume in whole-brain as assessed by traditional 1.5T DW-MRI as soon as possible and within twenty-four (24) hours post-procedure. [Time Frame: Day 0-1 days Post-Procedure]
    • Total new lesion volume is defined as the sum of all diffusion- positive new cerebral lesions in post-TAVR DW-MRI relative to the pre-TAVR DW-MRI scans. (in mm^3)
