Abstract

Devices, systems, and methods of evaluating a vascular system of a patient, are provided. In some instances, the method includes obtaining external imaging data associated with the heart; obtaining cardiac test data associated with the heart; generating a three-dimensional graphical representation of the heart using the external imaging data and the cardiac test data; and outputting the graphical representation of the heart to a display device, wherein the graphical representation of the heart includes a graphical representation of the cardiac test data. Corresponding systems and devices are also provided.

 output, to a display in communication with the processor, a screen display including:
 the three-dimensional model of the heart; 
 a first indicator along the vessel in the three-dimensional model of the heart representative of a location associated with the co-registered intravascular pressure data; and 
 a second indicator along the vessel in the three-dimensional model the heart representative of a location associated with the co-registered intravascular imaging data. 
 
   
     
     
         2 . The system of  claim 1 , further comprising the intravascular pressure-sensing guidewire, wherein the intravascular pressure-sensing guidewire is configured to obtain the intravascular pressure data while the intravascular pressure-sensing guidewire is positioned within the vessel. 
     
     
         3 . The system of  claim 1 , further comprising the external imaging device, wherein the external imaging device is configured to obtain the external imaging data.

         5 . The system of  claim 1 , further comprising the intravascular imaging catheter. 
     
     
         6 . The system of  claim 5 , wherein the intravascular imaging catheter comprises an intravascular ultrasound (IVUS) imaging catheter, and wherein the intravascular imaging data comprises IVUS imaging data. The system of  claim 1 , wherein the processor is further configured to:
 receive, from a myocardial perfusion imaging device in communication with the processor, myocardial perfusion imaging data associated with blood flow through the myocardium; and   generate the three-dimensional model of the heart based on the myocardial perfusion imaging data.   
     
     
         8 . The system of claim  7 , wherein the myocardial perfusion imaging device comprises a nuclear medicine imaging device. 
     
     
         9 . The system of  claim 1 , wherein the screen display further includes a third indicator of the co-registered pressure data. 
     
     
         10 . The system of  claim 9 , wherein the processor is configured to determine, based on the intravascular pressure data, a plurality of pressure ratios of the vessel, wherein the third indicator comprises a numerical indicator of at least one pressure ratio of the plurality of pressure ratios. 
     
     
         11 . The system of  claim 10 , wherein the processor is configured to:
 receive, from a user interface device in communication with the processor, a user input selecting a location of the vessel;   identify a pressure ratio of the plurality of pressure ratios associated with the selected location of the vessel; and   identify an intravascular image from the intravascular imaging data associated with the selected location of the vessel,   wherein the third indicator comprises a numerical indicator of the identified pressure ratio, and   wherein the screen display further comprises the identified intravascular image.
