Arms and Interventions

Arm Intervention/treatment
Harmony TPV System
Intervention Device: Harmony Transcatheter Pulmonary Valve and Delivery System

Outcome Measures

Primary Outcome Measures :
  1. Freedom from procedure- or device-related mortality at 30 days. [ Time Frame: 30 days ]
  2. Percentage of subjects with acceptable hemodynamic function composite at 6 months. [ Time Frame: 6 months ]

    Defined as:

    • Mean RVOT gradient as measured by continuous‐wave Doppler ≤40 mmHg ‐AND‐
    • Pulmonary regurgitant fraction as measured by magnetic resonance imaging <20%

Secondary Outcome Measures :
  1. Technical success at exit from catheterization lab/operating room (OR) [ Time Frame: At exit from catheterization lab/operating room (OR) ]
  2. Device Success out to 5 years [ Time Frame: 5 years ]
  3. Procedural Success at 30 days [ Time Frame: 30 days ]
  4. Freedom from TPV Dysfunction out to 5 years [ Time Frame: 5 years ]
  5. Assessment of safety [ Time Frame: 5 years ]
    All procedure-related serious adverse events. All device-related serious adverse events. Death (all-cause, procedural, and device-related).

  6. Characterization of quality of life scores out to 5 years [ Time Frame: 5 years ]
    As assessed via the SF-36 QOL form.

  7. Characterization of right ventricle remodeling following TPV implant [ Time Frame: 5 years ]
    As assessed via cardiac magnetic resonance imaging
