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.
