Abstract: The present invention relates to systems and methods for estimating prosthetic valve expansion diameter, and in particular, for system and methods for analyzing images acquired during prosthetic valve expansion, to identify structural components of the valve, determine dimensions thereof, and estimate at least one outer diameter of the prosthetic valve, and potentially a plurality of outer diameter along different axial positions of the prosthetic valve.

Abstract: Techniques for determining a position of a native leaflet can include identifying a position of a mineral formation on the native leaflet before implantation of a prosthetic valve and analyzing an image representing the prosthetic valve implanted within the cardiac vessel. The analysis can identify a position of the mineral formation within the cardiac vessel after the prosthetic valve is implanted. Based on the position of the mineral formation on the native leaflet before implantation of the prosthetic valve and the position of the mineral formation within the cardiac vessel, a position of the native leaflet within the cardiac vessel can be determined.
