#$%^&*AU2019222929A120190919.pdf#####PROSTHETIC HEART VALVE ABSTRACT A balloon-expandable prosthetic aortic heart valve (10) with a radially collapsed state and radially expanded state, the prosthetic aortic heart valve (10) comprising: a balloonexpandable frame (12) comprising a material selected from a group comprising stainless steel and a cobalt-chromium alloy, the frame comprising: an inflow row of openings (36) at an inflow end portion of the frame (12)； an outflow row of openings (40) at an outflow end portion of the frame (12)； and at least one intermediate row of openings (38) between the inflow row of openings (36) and outflow row of openings (40)； wherein the inflow row of openings (36) is formed by a circumferentially extending lower row of angled struts arranged end-to-end and a circumferentially extending first intermediate row of angled struts arranged end-to-end, the lower and first intermediate rows of angled struts interconnected by a plurality of substantially straight, axially extending struts； and wherein the outflow row of openings (40) is formed by a circumferentially extending upper row of angled struts arranged end-to-end and a circumferentially extending second intermediate row of angled struts arranged end-to-end, the upper and second intermediate rows of angled struts interconnected by a plurality of axially extending struts and a plurality of angularly spaced, axially extending commissure window frame portions, wherein each axially extending strut and each commissure window frame portion of the outflow row of openings (40) extends from a location defined by the convergence of the lower ends of two angled struts of the upper row of angled struts to another location defined by the convergence of the upper ends of two angled struts of the second intermediate row of angled struts.
