1. A side-delivered transcatheter prosthetic valve comprising:
- a compressible tubular frame having a side wall and a central axial lumen, said tubular frame having a height of 8-20 mm and a diameter of 40-80 mm,an atrial sealing cuff attached to a top edge of the side wall,a subannular anchoring component attached to the tubular frame, said subannular anchoring component selected from one or more of the group consisting of a lower tension arm extending from a distal side of the tubular frame, a proximal anchoring tab extending from a proximal side of the tubular frame, a ventricular sealing collar attached to a bottom edge of the side wall, and at least one tissue anchor to connect the tubular frame to native tissue, anda flow control component comprising a leaflet structure having three leaflets of pericardial material sewn to a leaflet frame to form a rounded cylinder mounted within the lumen of the tubular frame and configured to permit blood flow in a first direction through an inflow end of the valve and block blood flow in a second direction, opposite the first direction, through an outflow end of the valve,wherein the valve is compressible to a compressed configuration for introduction into the body using a delivery catheter for implanting at a mitral valve annulus or tricuspid valve annulus of a patient, said delivery catheter having an internal diameter from 22 Fr (7.33 mm) to 34 Fr (11.33 mm),said compressed configuration having a long-axis that is substantially parallel to a length-wise cylindrical axis of the delivery catheter, and substantially orthogonal to the blood flow through the flow control component mounted in the central axial lumen,said compressed configuration having a height and a width to fit within the delivery catheter, the height and width of the compressed configuration compressed by longitudinal/length-wise rolling or folding,wherein the valve is expandable to an expanded configuration having a long-axis substantially orthogonal to the blood flow through the flow control component mounted in the central axial lumen,said tubular frame and said atrial sealing cuff having a polyester cover, and said tubular frame and said atrial sealing cuff made from superelastic shape-memory material selected from Ni—

Abstract
The invention relates to a transcatheter heart valve replacement (A61F2/2412), and in particular to a side delivered large diameter, low profile transcatheter prosthetic valve having a compressible tubular frame having a side wall and a central axial lumen, said tubular frame having a height of 8-20 mm and a diameter of 40-80 mm, an atrial sealing cuff, a subannular anchoring component, and aa flow control component comprising a leaflet structure, wherein the valve is side-delivered longitudinally to a mitral valve annulus or tricuspid valve annulus of a patient using a 22-34 Fr delivery catheter.
