METHOD OF IMAGING FOR HEART VALVE IMPLANT PROCEDURE
First Claim
1. A method of imaging a patient for a heart valve implant procedure, comprising the steps of:
- positioning the patient relative to an articulated imaging apparatus to provide isocentric positioning of an aortic root of the patient'"'"'s heart relative to the imaging apparatus;
inducing rapid ventricular pacing in the patient;
injecting a contrast agent into the patient during the rapid ventricular pacing state;
imaging a region of the aortic root using the articulated imaging apparatus to obtain image data for constructing a three-dimensional image; and
constructing a three dimensional image using data from the imaging step.

Abstract
A method as a workflow for imaging for a heart valve implant procedure includes positioning the patient and an articulated imaging apparatus relative to one another, inducing rapid ventricular pacing in the patient, and imaging a region of the patient'"'"'s heart to obtain image date for a three-dimensional image. The three-dimensional data is used to construct a three-dimensional image of the region of the patient'"'"'s heart an the three-dimensional image is displayed for use in the implanting of the replacement heart valve. Optional steps may include obtaining a real time two-dimensional image of the patient'"'"'s heart and superimposing the real time two-dimensional image with the constructed three dimensional image. The replacement valve is moved into position in the patient'"'"'s heart during rapid ventricular pacing and breath hold using the superimposed two-dimensional and three-dimensional image information.

15. A method of imaging a patient for a heart valve implant procedure, comprising the steps of:
-
position the patient relative to an imaging apparatus to provide isocentric positioning of a predetermined structure of the patient'"'"'s heart relative to the imaging apparatus; induce rapid ventricular pacing in the patient and instruct the patient to breath-hold; inject a contrast agent into a portion of the patient'"'"'s heart during the rapid ventricular pacing state; imaging a region of the patient'"'"'s heart using the imaging apparatus to obtain image data for constructing a three-dimensional image; construct a three dimensional image using data from the imaging step; and using the constructed three dimensional image during implant of a heart valve in the patient'"'"'s heart.
