摘要
The invention relates to a transcatheter heart valve replacement (A61F2/2412), and in particular a side delivered transcatheter prosthetic heart valve having a collapsible inner flow control component, and an outer annular support frame having compressible wire cells that facilitate folding flat along the z-axis and compressing the valve vertically along the y-axis, or orthogonally to the central axis of the flow control component, allowing a very large diameter valve to be delivered and deployed to the tricuspid valve from the inferior vena cava or superior vena cava, or trans-atrially to the mitral valve, the valve having a height of about 5-60 mm and a diameter of about 25-80 mm, without requiring an oversized diameter catheter and without requiring delivery and deployment from a catheter at an acute angle of approach.
