摘要
A prosthetic heart valve includes a frame, a valvular structure coupled to the frame, and a sealing member coupled to the frame. The frame has inflow and outflow ends and a lumen extending therebetween. The frame includes struts that form cells, and the cells are arranged in three rows. The frame is radially expandable from a collapsed state to an expanded state. The valvular structure includes a plurality of leaflets configured to allow blood flow through the lumen of the frame from the inflow end to the outflow end and to block blood flow through the lumen of the frame from the outflow end to the inflow end. The sealing skirt extends from an intermediate location of the frame disposed between the inflow and outflow ends to the inflow end of the frame. The sealing skirt covers two rows of cells to block blood flow through the cells.
