1. A method for sizing a heart valve annulus, comprising:
preparing a sizing device including a proximal handle having an actuator, a shaft coupled to and extending in a distal direction from the handle, adjustably-sized annuloplasty ring replica coupled to a distal end of the shaft, the annuloplasty ring replica defining a shape of the annulus being sized and being biased to a maximum size, the sizing device having a display window on the handle configured to provide a number selected from a plurality of available repair ring sizes indicating the nearest size of annuloplasty ring in even 2 mm increments that corresponds to a current size of the annuloplasty ring replica;
reducing the size of the adjustable ring replica to less than the maximum size using the actuator;
positioning the adjustable ring replica at or near a patient's native valve annulus;
permitting the size of the adjustable ring replica to increase until an outer surface contacts the valve annulus; and
determining an appropriate size of prosthetic annuloplasty ring for the valve annulus by observing the number in the display window when the adjustable ring replica contacts the valve annulus.
