About this trial
To evaluate the safety and efficacy of Siegel™ TAVR System in the treatment of subjects with symptomatic severe native aortic stenosis.
Eligibility criteria
Qualifiers
Age ≥ 18 years
Symptomatic, severe native calcific aortic stenosis in subjects at low, intermediate or high surgical risk AVA ≤ 1.0 cm2 or AVA index ≤ 0.6 cm2/m2 or Jet velocity ≥ 4.0 m/s or mean gradient ≥ 40 mmHg or dimensionless Index <0.25
New York Heart Association Functional Class ≥ 2
Requires aortic valve replacement and is indicated for TAVR as determined by the Heart Team (composed of an experienced interventional cardiologist and an experienced cardiac surgeon)
Disqualifiers
Cardiac anatomy precluding safe placement of a transcatheter aortic valve.
Iliofemoral vessel characteristics (vessel diameter <5.5mm for smaller THV systems [20-26mm valve sizes] or <6.0mm for larger THV systems [29mm or larger valve sizes]) that would preclude safe placement of commercially available transcatheter aortic valves (SAPIEN 3 or Evolut)
Pre-existing prosthetic heart valve or ring except in the mitral position.
Unicuspid aortic valve
