Abstract
A prosthetic heart valve for replacing a native valve includes a collapsible and expandable stent extending between a proximal end and a distal end, the stent including an annulus section adjacent the proximal end and an aortic section adjacent the distal end. The annulus section has cells arranged in at least one annulus row, each annulus row having a same first number of cells, the first number defining a first cell density. The aortic section has cells arranged in at least one aortic row, each aortic row having a same second number of cells, the second number defining a second cell density, the first cell density and the second cell density being different. A valve assembly is disposed within the stent.
