VenusP-Valve Pivotal Study (PROTEUS STUDY)

About

Brief Summary

A prospective, multi-center, non-randomized interventional study to evaluate the safety and effectiveness of the VenusP-ValveTM System in patients with native right ventricular outflow tract (RVOT) dysfunction.

Post procedure, a clinical visit will be scheduled at pre-discharge, 30 days, 6 months, 12 months, and annually thereafter to 10 years.

About 60 subjects will be enrolled in this study. Data analysis will be performed after all enrolled subjects complete 6-month follow-up and the primary endpoint analysis report will be submitted to FDA for PMA approval.

Inclusion Criteria:

  • Weight ≥25kg (55 lbs.)
  • Age ≥ 12 years olds
  • Patients have a dysfunctional native RVOT with severe pulmonary regurgitation (i.e., severe pulmonary regurgitation as determined by echocardiography or pulmonary regurgitant fraction ≥30% as determined by cardiac magnetic resonance imaging) and without significant pulmonary stenosis (significant pulmonary stenosis is defined as gradient more than 25mmHg) and are clinically indicated for intervention:
  • For symptomatic patients, fitting the following criteria:
  • Severe pulmonary regurgitation measured by echocardiogram or pulmonary regurgitant fraction ≥30% measured by CMR 2) For asymptomatic patients, including any 2 of the following criteria:
  • Mild or moderate RV or LV systolic dysfunction.
  • Severe RV dilation (RVEDVI ≥145 mL/m2 or RVESVI ≥ 75 mL/m2or RVEDV >2 × LVEDV).
  • Progressive reduction in objective exercise tolerance. 4. Patient is willing to consent to participate in the study and will commit to completion of all follow-up requirements.

Exclusion Criteria:

  • Clinical or biological signs of infection including active endocarditis.
  • Echocardiographic evidence of intracardiac mass, thrombus, or vegetation.
  • Leukopenia, anemia, thrombocytopenia, or any known blood clotting disorder, deemed clinically significant after consultation with Haemato-oncology specialists.
  • Inappropriate anatomy for femoral or right internal jugular vein (RIJ) introduction and delivery of the VenusP-ValveTM System.
  • RVOT anatomy or morphology that is unfavorable for device anchoring.
  • Anatomy unable to accommodate VenusP-Valve delivery system.
  • Angiographic evidence of coronary artery compression that would result from transcatheter pulmonary valve replacement (TPVR).
  • Emergency interventional/surgical procedures within 30 days prior to the index procedure.
  • Planned significant and relevant concomitant procedure at time of VenusP-Valve implant.
  • Any planned interventional/surgical procedures to be performed within the 30 days follow-up from VenusP-Valve implant.
  • Known history of intravenous drug abuse in the past 5 years, without certificate of completion of rehabilitation from a specialist.
  • Major or progressive non-cardiac disease resulting in a life expectancy of less than one year.
  • Known hypersensitivity or contraindication to antiplatelet, antithrombotic medications, or nitinol (titanium or nickel) leading to be unable to undergo index procedure per physicians' judgement
  • Positive pregnancy test at baseline (prior to CT angiography and again prior to implant procedure) in female patients of child-bearing potential.
  • Currently participating in an investigational drug or another device study.
  • Patient or guardian unwilling or unable to provide written informed consent or comply with follow-up requirements.
  • The investigators consider that the patients are not suitable to participate in this research.
