Transcatheter Pulmonary Valve Implantation Using Self-Expandable Percutaneous Pulmonary Valve System: 3-Year CE Study...

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Medical Devices

Background:

• Pulmonary regurgitation is a frequent complication post-tetralogy of Fallot repair.
• Existing percutaneous pulmonary valves are often limited to smaller right ventricular outflow tracts (RVOTs).

Purpose of the Study:

• To evaluate the acute and 3-year follow-up results of the self-expandable VenusP-valve.
• Assess the safety and efficacy of VenusP-valve implantation in patients with severe pulmonary regurgitation.

Main Methods:

• A multicenter Conformité Européenne (CE) study was conducted from August 2016.
• 81 patients with pulmonary regurgitation underwent VenusP-valve implantation.
• Patients were assessed over a 3-year follow-up period.

Main Results:

• Successful VenusP-valve implantation in all patients.
• No early or late mortality observed.
• Satisfactory valve function and significant right ventricular remodeling occurred in all patients over 3 years. Few complications included hemoptysis, ventricular tachycardia, endocarditis, and thrombus formation, all managed successfully.

Conclusions:

• The VenusP-valve demonstrates promising safety and durability for percutaneous pulmonary valve implantation.
• The study supports the use of VenusP-valve in patients with severe pulmonary regurgitation.
• Long-term evaluation of the VenusP-valve is recommended.
