Impact of Postdilatation With the InterValve V8 Aortic Valvuloplasty Balloon Following TAVI Procedure

Official Title

Impact of Postdilatation With the InterValve V8 Aortic Valvuloplasty Balloon Following Medtronic CoreValve or Other Self-Expanding TAVI Procedure (PostCorE)

Brief Summary

      This study is designed to monitor the safety and performance of the V8 balloon when used as a
      postdilatation balloon in self-expanding Transcatheter Aortic Valve Implantation (TAVI)
      device procedures. The study product is CE marked for balloon aortic valvuloplasty (BAV), and
      is being investigated for an expanded intended use.

Detailed Description

      The study is a prospective, multi-center, single arm open-label clinical study involving up
      to 5 centers and a minimum of 20 subjects. Up to 50 subjects may be enrolled in this study.
      The first 3 post-dilatation procedures for each investigator will be considered roll-ins and
      not included in the main study analyses. Subjects will exit the study at hospital discharge
      or 7 days post treatment, whichever comes first. The expected duration of the clinical
      investigation is approximately 6 months.

      Subjects implanted with the CoreValve or other commercially available self-expanding TAVI and
      with the use of the V8 as a postdilatation balloon may be enrolled in this study. The subject
      will exit the study after the predischarge ECHO where the Paravalvular Leak (PVL)
      measurements are taken or resolution of a V8 related AE (if applicable).

Eligibility Criteria

        Inclusion Criteria:

          -  Subjects with severe symptomatic aortic stenosis (AS) indicated and scheduled for a
             transcatheter aortic valve implant (TAVI) with the Medtronic CoreValve or another
             self-expanding TAVI device.

          -  The TAVI device size is determined preoperatively with CTA according to standard
             guidelines. Patients may undergo transfemoral, subclavian, or transaortic approach.

          -  Balloon postdilatation (BPD) is carried out after CoreValve or other self-expanding
             TAVI device implantation if, based on operator's judgment, BPD is indicated because of
             presence of paravalvular leak (PVL).

          -  Hemodynamically stable for 3 - 10 minutes after the TAVI procedure.

          -  Probable survival to hospital discharge.

          -  Subject is competent, willing to comply with evaluations, understands risks, benefits
             and alternatives and has signed the Informed Consent Form.

        Exclusion Criteria:

          -  Cardiogenic shock, as defined by a consistent systolic blood pressure <80 mmHg off
             vasopressors or <90 mmHg on vasopressors.

          -  PVL occurring secondary to excessively high or low valve positioning.

          -  Trauma or significant structural damage to underlying native tissue calls for emergent
             intervention or threatens long-term outcome prior to the BPD.

          -  Patients receiving two valves (i.e. aortic THV valve in valve).

          -  Patients with AS secondary to congenital valve disease including bicuspid aortic
             valve.

          -  PVL occurring due to TAVI device under sizing. Example of determining the undersizing
             is to calculate the Cover Index which represents the percent of over sizing of the
             nominal transcatheter heart valve (THV) area compared to the measured native valve
             annulus area. Under sizing is defined as TAVI screening CTA with a pre procedure cover
             index by area of <5%.

          -  Vulnerable subjects and any subjects incapable of giving consent, including patients
             with incurable diseases, patients in emergency situations, ethnic minority groups,
             homeless persons, nomads, refugees, minors, and subjects with cognitive impairment,
