PCI Planning Interface Integrating Angiography and Pressure Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for planning percutaneous coronary interventions (PCI) face challenges in integrating angiography and physiologic data, making it difficult to determine the optimal stent positioning, length, and diameter, and predict the efficacy of the intervention.
Innovation Solution
A graphical user interface is provided that allows clinicians to visualize a stent positioned within a blood vessel, with the ability to modify the stent's position and length based on user input. The system includes pressure measurements and angiography data to determine physiological parameters for stent deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If clinicians rely on conventional angiography and pressure measurements separately, then data collection is simple, but integration of various data sources is difficult and therapeutic planning is impaired
Solution Approach 1:
The patent merges angiography imaging data and physiologic pressure measurements into a single integrated graphical user interface. The system co-registers pressure ratio data with angiographic images, allowing clinicians to view both data types simultaneously in one unified display, eliminating the need to switch between separate systems and enabling comprehensive therapeutic planning.
Solution Approach 2:
The graphical user interface serves multiple functions: displaying angiographic images, overlaying pressure ratio data, visualizing stent positioning, and enabling interactive manipulation of stent parameters. This multi-functional interface consolidates what would otherwise require separate tools and systems, improving information integration without proportionally increasing complexity.
2Loss of information
If clinicians use separate tools for angiography and pressure measurements, then individual measurements are accurate, but connection between angiography and physiologic data is not meaningful
Solution Approach 1:
The system combines angiographic and physiologic data into a single co-registered display where pressure ratio values are overlaid on the angiographic image at their anatomical locations. This merging creates meaningful connections between the two data types, showing clinicians exactly where pressure changes occur within the vascular anatomy without requiring manual correlation or separate analysis.
Solution Approach 2:
The graphical user interface acts as an intermediary that automatically co-registers and correlates angiographic image data with pressure measurement data. The system handles the complex task of matching spatial locations between imaging and physiology, presenting clinicians with a pre-integrated view that eliminates the need for manual data alignment while preserving measurement accuracy.
3Reliability
If clinicians manually plan stent parameters without integrated data, then planning process is simple, but prediction of intervention efficacy is limited
Solution Approach 1:
The system merges therapeutic stent planning with integrated angiographic and physiologic data display. Clinicians can interactively position and size stents directly on the co-registered images, with the interface providing immediate visual feedback on how proposed stent placements will affect pressure ratios and blood flow. This integration improves prediction reliability by allowing clinicians to evaluate multiple scenarios before committing to a treatment plan.
Solution Approach 2:
The system allows clinicians to perform preliminary virtual stent placement and evaluate predicted outcomes before actual intervention. By enabling pre-planning with integrated data visualization, clinicians can optimize stent positioning and sizing, reducing the need for adjustments during the actual procedure and improving overall treatment efficacy prediction.
4Measurement precision
If no visualization of stent positioning is provided, then interface is simple, but determination of optimal stent position, length, and diameter is difficult
Solution Approach 1:
The system merges stent visualization with the co-registered angiographic and pressure data in a single graphical interface. Stents are displayed as graphical representations overlaid on the angiographic images, with pressure ratio information visible in the same view. This merging allows clinicians to precisely determine optimal stent positioning, length, and diameter by directly observing the relationship between stent placement and pressure measurements without switching between multiple displays or tools.
Solution Approach 2:
The interface uses color coding and visual indicators to highlight pressure ratio changes and stent positioning relationships. By applying visual enhancements such as color-coded pressure gradients and highlighted stent boundaries, the system improves measurement precision for stent planning without adding significant complexity to the user interface.

AI summary
A method of evaluating a vessel of a patient is provided. The method includes outputting, to a display device, a screen display including: a visualization based on pressure measurements obtained from a first instrument and a second instrument positioned within the vessel of the patient while the second instrument is moved longitudinally through the vessel and the first instrument remains stationary within the vessel; and a visual representation of a vessel; receiving a user input to modify the visualization to simulate a therapeutic procedure; and updating the screen display, in response to the user input, including modifying the visualization based on the user input. A system for evaluating a vessel of a patient is also provided. The system includes first and second instruments sized and shaped for introduction into the vessel of the patient; and a processing system communicatively coupled to the first and second instruments and a display device.
