Abstract
A sizer for assessing the geometry of a heart valve annulus. The sizer preferably includes a circular sizing portion for measuring the diameter of the valve annulus. The sizing portion has radial spokes. The spokes are used to compare the symmetry of the commissures to the expected symmetry of a normal heart valve. The sizer preferably has one or more legs attached to the sizing portion for comparing the contour of the line of valve leaflet attachment to the expected contour of a normal heart valve having a diameter substantially equivalent to the measured diameter of the valve annulus.
