Abstract
Aspects of the disclosure include a prosthetic heart valve including a stent structure forming a plurality of commissure posts, a valve structure supported by the stent structure, a base supporting the stent structure and at least one radiopaque element positioned around the base. The radiopaque element can include a band extending around the base. In some embodiments the band is coiled. The band can optionally include a badge with an indicator specifying properties of the valve and viewable under fluoroscopy. In some embodiments, the radiopaque element is a badge that can have an indicator. The radiopaque elements of the disclosure increase ease and accuracy in the positioning of a percutaneously delivered replacement valve within a previously implanted valve of the disclosure.
