Evaluating prosthetic heart valve placement
First Claim
1. A computer-implemented method for evaluating the placement of a prosthetic device in a patient'"'"'s body, comprising:
- designating one or more positions in at least one of one or more depictions of an anatomical region of interest of the patient'"'"'s body that includes a first anatomical structure of interest in which the prosthetic device is to be placed, wherein each of the one or more depictions shows the first structure of interest, a blood pool volume of a second anatomical structure of interest, or both, and wherein each designated position corresponds to a respective position in the first structure of interest at which the prosthetic device may be placed; and
for each of the one or more designated positions, predicting an amount of blood flow obstruction through the second structure of interest that would be caused if the prosthetic device was to be placed at a corresponding position in the first structure of interest.

Abstract
A method for evaluating the placement of a prosthetic heart valve in a structure of interest. The method comprises acquiring one or more depictions of an anatomical region of interest that includes the structure of interest, wherein each depiction shows the structure of interest and/or the blood pool volume of the left ventricular outflow tract (LVOT) of the patient'"'"'s heart. The method further comprises designating one or more positions in at least one of the one or more depictions wherein each position corresponds to a respective position in the structure of interest at which the prosthetic valve may be placed. The method still further comprises predicting, for each of the one or more designated positions, an amount of blood flow obstruction through the LVOT of the patient'"'"'s heart that would occur if the prosthetic valve was to be placed at a corresponding position in the structure of interest.

12. A system for evaluating the placement of a prosthetic device in a patient'"'"'s body, comprising:
-
an electronic processor; and an electronic memory device having instructions stored therein, wherein the processor is configured to access the memory device and execute the instructions stored therein such that it is configured to; designate one or more positions in at least one of one or more depictions of an anatomical region of interest of the patient'"'"'s body that includes a first anatomical structure of interest in which the prosthetic device is to be placed, wherein each of the one or more depictions shows the first structure of interest, a blood pool volume of a second anatomical structure of interest, or both, and wherein each position corresponds to a respective position in the first structure of interest at which the prosthetic device may be placed; and for each of the one or more designated positions, predict an amount of blood flow obstruction through the second structure of interest that would be caused if the prosthetic device was to be placed at a corresponding position in the first structure of interest. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

34. A method for use in evaluating the placement of a prosthetic device in a patient'"'"'s body, comprising:
-
designating a position in at least one of one or more depictions of an anatomical region of interest of the patient'"'"'s body that includes a first anatomical structure of interest in which the prosthetic device is to be placed, wherein each of the one or more depictions shows the first structure of interest, a blood pool volume of a second anatomical structure of interest, or both, and wherein the designated position corresponds to a position in the first structure of interest at which the device may be placed; determining for the designated position a cross-sectional surface area of the blood pool volume of the second anatomical structure of interest; and evaluating blood flow obstruction through the second structure of interest that would be caused if the prosthetic device was to be placed at a position in the first structure of interest corresponding to the designated position based on the determined cross-sectional surface area. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41)

42. A system for evaluating the placement of a prosthetic device in a patient'"'"'s body, comprising:
-
an electronic processor; and an electronic memory device having instructions stored therein, wherein the processor is configured to access the memory device and execute the instructions stored therein such that it is configured to; designate a position in at least one of one or more depictions of an anatomical region of interest of the patient'"'"'s body that includes a first anatomical structure of interest in which the prosthetic device is to be placed, wherein each of the one or more depictions shows the first structure of interest, a blood pool volume of a second anatomical structure of interest, or both, and wherein the designated position corresponds to a position in the first structure of interest at which the device may be placed; and for the designated position, determine a cross-sectional surface area of the blood pool volume of the second anatomical structure of interest for use in evaluating blood flow obstruction through the second structure of interest that would be caused if the prosthetic device was to be placed at a corresponding position in the first structure of interest. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49, 50, 51, 52)
