  Purpose

The purpose of this study is to confirm the short-term hemodynamic effectiveness results achieved by real-world providers are equivalent to the historical control established in the IDE study.


Condition Intervention
Dysfunctional RVOT Conduit
Device: Melody® Transcatheter Pulmonary Valve

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Implantation of the Medtronic Melody Transcatheter Pulmonary Valve (TPV) in Patients With Dysfunctional Right Ventricular Outflow Tract (RVOT) Conduits: A Post-Market Approval Study

Further study details as provided by Medtronic Heart Valves:

Primary Outcome Measures:
  • Acceptable TPV hemodynamic function at six months after successful TPV implantation [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • % of patients with procedural success [ Time Frame: 5 year ] [ Designated as safety issue: No ]
  • % of subjects with serious procedural adverse events [ Time Frame: 5 year ] [ Designated as safety issue: No ]
  • % of subjects with serious device-related adverse events at six months post-implant [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • Incidence of serious device-related adverse events over the follow-up period [ Time Frame: 5 year ] [ Designated as safety issue: No ]
  • Freedom from stent fracture [ Time Frame: 5 year ] [ Designated as safety issue: No ]
  • Freedom from reintervention on the TPV [ Time Frame: 5 year ] [ Designated as safety issue: No ]
  • Freedom from RVOT conduit reoperation [ Time Frame: 5 year ] [ Designated as safety issue: No ]
  • Freedom from death (all-cause, procedural, and device-related) [ Time Frame: 5 year ] [ Designated as safety issue: No ]
  • Changes in NYHA functional classification [ Time Frame: 5 year ] [ Designated as safety issue: No ]

  Eligibility

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Existence of a full (circumferential) RVOT conduit that was equal to or greater than 16 mm in diameter when originally implanted
  • Dysfunctional Right Ventricular Outflow Tract conduits with a clinical indication for interventions (regurgitation ≥ moderate regurgitation, Stenosis: mean RVOT gradient ≥ 35 mmHg)

Exclusion Criteria:

  • Implantation in the aortic or mitral position
  • Venous anatomy unable to accommodate a 22-fr size introducer sheath
  • Obstruction of the central veins
  • Clinical or biological signs of infection including active endocarditis
