摘要：
A prosthetic heart valve configured to replace a native heart valve and havinga support frame configured to be reshapedinto an expanded form in order to receive and/or support an expandableprosthetic heart valve therein. A dual-wireform support frameincluding an upper and a lower wireform permits expansion of the valve by oneor two valve sizes, for example, with a 2-mm gapbetween each valve size. The lower wireform has a relatively shallowundulation so that it may stretch apart by a small amount andthen prevent further expansion of the valve.
