Purpose of Technology

Percutaneous pulmonary valve implantation (PPVI), also referred to as transcatheter or catheter-based pulmonary valve implantation or replacement, is a minimally invasive heart surgery in patients with right ventricular outflow tract (RVOT) defects. The procedure involves the percutaneous, catheter-based deployment and placement of a pulmonary valve prosthesis. The purpose of PPVI is to improve hemodynamics, cardiopulmonary function, and survival while delaying the need for surgical repair of a dysfunctional RVOT.

Relevant Questions

  • Is PPVI for RVOT effective, i.e., does it improve hemodynamic measures, cardiopulmonary function, and survival, and reduce pulmonary artery regurgitation and disease-related mortality without leading to a high number of failures or reinterventions?

  • Is PPVI safe?

  • Have definitive patient selection criteria been established for PPVI for RVOT?
