This trial is active, not recruiting.

Conditions complex congenital heart defect, dysfunctional rvot conduits
Treatment transcatheter pulmonary valve replacement
Sponsor Medtronic Heart Valves
Start date January 2007
End date May 2015
Trial size 150 participants
Trial identifier NCT00740870, G050186


The primary objective is to confirm the long-term functionality of implantation of the Medtronic Melody TPV at 5 years is no worse than the historical control established through literature review. The secondary objectives are to assess safety, procedural success, and clinical utility of transcatheter implantation of the Melody TPV.
