摘要:
A sequentially deployed prosthetic cardiac valve includes a self-expanding frame having an atrial skirt, a ventricular skirt, and an annular region disposed therebetween. A first anterior tab is disposed on an anterior portion of the frame. A posterior tab is on a posterior portion of the self-expanding frame. The frame may be designed so that any portion may expand sequentially in any desired order. For example, a portion of the first anterior tab and a portion of the posterior tab may partially self-expand first. Next, the first anterior tab may fully self-expand before the posterior tab fully self-expands. The posterior tab may fully self-expand next followed by the ventricular skirt, or the ventricular skirt may self-expand next followed by full expansion of the posterior tab.
