Modular valve prosthesis with anchor stent and valve component

A method of implanting a prosthetic valve at a location of a native aortic valve comprising the steps of:

• advancing an anchor stent in a radially compressed configuration into the aorta, wherein the anchor stent comprises a tubular frame member, a proximal arm component extending from a first end of the tubular frame member, and a plurality of attachment members extending inwardly from an inner surface of the tubular frame member;
• deploying the anchor stent at a location within the aorta such that the tubular frame member expands from the radially compressed configuration to a radially expanded configuration engaging an inner wall surface the aorta and the proximal arm component expands from the radially compressed configuration to the radially expanded configuration engaging an inner wall surface of the sinuses of the aortic valve;
• separately advancing a valve component in a radially compressed configuration into the aorta, wherein the valve component comprises a valve frame and a prosthetic valve coupled to the valve frame;
• deploying the valve component at the native aortic valve such that the valve frame expands from the radially compressed configuration to a radially expanded configuration with a first portion of the valve frame engaging the native aortic valve and a second portion the valve frame engaging the attachment members of the tubular frame member of the anchor stent.
