A prosthetic heart valve comprising: a stent comprising a plurality of struts formed with alternating bends, said stent comprising an inflow end and an outflow end , wherein: the stent is radially compressible to a compressed state and radially expandable to its functional size, the stent has a substantially cylindrical shape when being expanded to its functional size, the plurality of struts forms a plurality of rows of cells, said rows of cells extending along a circumferential direction of the stent , the plurality of rows of cells includes a row of inflow cells at the inflow end , and a row of outflow cells at the outflow end , the stent has 9 inflow cells, 5 rows of struts, and 3 outflow cells, or the stent has 9 inflow cells, 5 rows of struts, and 6 outflow cells, or the stent has 12 inflow cells, 5 rows of struts, and 3 outflow cells, or the stent has 12 inflow cells, 6 rows of struts, and 3 outflow cells, or the stent has 12 inflow cells, 5 rows of struts, and 6 outflow cells, or the stent has 15 inflow cells, 5 rows of struts, and 3 outflow cells, or the stent has 15 inflow cells, 6 rows of struts, and 3 outflow cells, or the stent has 15 inflow cells, 5 rows of struts, and 6 outflow cells, or the stent has 15 inflow cells, 7 rows of struts, and 5 outflow cells, or the stent has 18 inflow cells, 5 rows of struts, and 3 outflow cells, or the stent has 18 inflow cells, 5 rows of struts, and 6 outflow cells, a leaflet assembly mounted to the stent , characterised in that when the stent is seen in a flattened view, the outflow cells each have a width along the circumferential direction of the stent that corresponds to the combined width of two or four inflow cells. the stent is radially compressible to a compressed state and radially expandable to its functional size, the stent has a substantially cylindrical shape when being expanded to its functional size, the plurality of struts forms a plurality of rows of cells, said rows of cells extending along a circumferential direction of the stent , the plurality of rows of cells includes a row of inflow cells at the inflow end , and a row of outflow cells at the outflow end , the stent has 9 inflow cells, 5 rows of struts, and 3 outflow cells, or the stent has 9 inflow cells, 5 rows of struts, and 6 outflow cells, or the stent has 12 inflow cells, 5 rows of struts, and 3 outflow cells, or the stent has 12 inflow cells, 6 rows of struts, and 3 outflow cells, or the stent has 12 inflow cells, 5 rows of struts, and 6 outflow cells, or the stent has 15 inflow cells, 5 rows of struts, and 3 outflow cells, or the stent has 15 inflow cells, 6 rows of struts, and 3 outflow cells, or the stent has 15 inflow cells, 5 rows of struts, and 6 outflow cells, or the stent has 15 inflow cells, 7 rows of struts, and 5 outflow cells, or the stent has 18 inflow cells, 5 rows of struts, and 3 outflow cells, or the stent has 18 inflow cells, 5 rows of struts, and 6 outflow cells, a leaflet assembly mounted to the stent , characterised in that when the stent is seen in a flattened view, the outflow cells each have a width along the circumferential direction of the stent that corresponds to the combined width of two or four inflow cells. <EOS>
