Treatment and study plan

AltaValve System.

Device

Transcatheter Mitral Valve Replacement.

Primary outcomes

  1. Composite of all-cause mortality or heart failure hospitalization.

    Time frame: 12 months.

Secondary outcomes

  1. All-cause mortality, disabling stroke, acute kidney injury (stage 3 or with renal replacement), mitral valve re-intervention (surgical or transcatheter), major bleeding requiring intervention.

    Time frame: 30 Days or hospital discharge (whichever is longer).

    Composite.

  2. Technical success.

    Time frame: Day 0.

    Technical success will be considered achieve when all of the following are present:

    • Successful device placement.
    • Reduction in mitral regurgitation grade to ≤ 2+.
  3. Mitral valve re-intervention.

    Time frame: At 30 days, 6 months, 1 year, and annually thereafter for up to 5 years.

    Quality of life improvement.

  5. Changes in Six-minute walk test (6MWT).

    Time frame: 6 months and 1 year.

    Quality of life improvement.

  6. New pacemaker rate.

    Time frame: 1 month, 6 months and 1 year.
