Brief Summary

The primary objective of this study is to demonstrate the safety and effectiveness of the Harmony TPV system as measured by freedom from procedure or device-related mortality at 30 days and percentage of subjects with acceptable hemodynamic function at 6 months. 

The objective of the Harmony TPV Roll-in phase is to confirm the procedural feasibility, hemodynamic performance and safety profile of the Harmony TPV 25 prior to the Harmony TPV 25 becoming available for implant at all sites.  The Roll-in phase is intended to provide Study Proctors familiarity and added expertise in the implant technique for Harmony TPV 25 prior to proctoring all sites in implanting the Harmony TPV 25.

Inclusion Criteria

Inclusion Criteria:

Participant has pulmonary regurgitation as per one or more of the following criteria:

  • Severe pulmonary regurgitation as measured by Doppler echocardiography, or
  • Pulmonary regurgitant fraction ≥ 30% as measured by cardiac magnetic resonance imaging

Clinical indication for surgical placement of a RV‐PA conduit or prosthetic pulmonary valve per one or more of the following criteria:

  • Participant is symptomatic secondary to pulmonary insufficiency (e.g. exercise intolerance, fluid overload) as classified by the investigator, or
  • Right ventricular end diastolic volume index (RVEDVi) ≥ 150 ml/m2, or
  • Participant has RVEDV: LVEDV Ratio ≥ 2.0

Participant is willing to consent to participate in the study and will commit to completion of all followuprequirements

Exclusion Criteria
