简要总结

The purpose is to evaluate the safety, effectiveness and performance of Venus-Vitae Transcatheter Heart Valve System in patients with severe aortic stenosis.

详细描述

This trial is a prospective, multi-center, non-randomized interventional study to evaluate the safety, effectiveness and performance of the Venus-Vitae Transcatheter Heart Valve System in patients with severe aortic stenosis. Clinical visits will be scheduled at screening, pre-discharge, 30 days, 6 months, 12 months and annually thereafter to 5 years.

入选标准

  • Age ≥ 18 years
  • Patients with the symptoms of severe aortic stenosis
  • Severe aortic stenosis (AS, grade 3+), defined as AVA ≤ 1 cm2 (AVAi ≤ 0.6 cm2/m3) or Vmax ≥ 4.0 m/s or MPG ≥ 40 mmHg determined by echocardiography
  • Patients deemed for cardiac intervention by a heart team
  • Patients of all surgical risk categories can be enrolled in this study, but should follows local medical practices and regulatories.
  • Patients or their legal reprensentatives are willing to participate in the study and provide written informed consent, and agree to follow the follow-up requirements

排除标准

  • A subject meeting any of the following criteria shall be excluded:
  • Co-morbidities
  • Previous mechanical or biological aortic valve replacement
  • Untreated mitral, tricuspid or pulmonary valve diseases requiring procedural intervention
  • Acute myocardial infact within 30 days prior to index procedure
  • Untreated clinical significant coronary artery disease requiring revascularization
  • Any therapeutic invasive cardiac procedure performed within 30 days (or drug-eluting coronary stent/scaffold implant within 6 months)
  • Sever symptomatic carotid artery stenosis
  • Stroke or TIA within 3 months or Modified Rankin Scale ≥ 4 disability

  • Inappropriate anatomy for femoral introduction and delivery of study device
  • Native aortic valve geometry and size unfavorable for study device anchoring General
  • Haemodynamics instability requiring inotropic support or intra-aortic balloon pump (IABP) or other hemodynamic support device, or any mechanical heart assistance
  • Known hypersensitivity or contraindication to antiplatelet, antithrombotic medications, or cobalt-chromium leading to be unable to undergo index procedure per physicians' judgement
  • Life expectancy ≤ 1 year due to noncardiac reasons
  • Active infection requiring antibiotic therapy including infective endocarditis
  • Planned relevant concomitant procedure within 30 days post index procedure
  • Pregnant, breastfeeding or intend to become pregnant within 1 year
