Solution Overview

Problem

Existing methods for determining the SYNTAX Score for coronary artery disease are subjective and time-consuming, leading to variability in decision-making for interventions like PCI or CABG, especially in complex cases with multiple lesions or left main artery involvement.

Innovation Solution

An automated method and system for vascular state scoring that uses image data to determine vascular metrics, including stenosis and other parameters, to calculate a SYNTAX-like score objectively and quickly, reducing subjectivity and time required for decision-making.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual subjective assessment is used to determine SYNTAX Score, then clinical judgment and experience can be applied, but the process is time-consuming and shows variability in decision-making

Engineering Contradiction:
Improveconsistency of decision-makingVSAvoidtime required for score calculation
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the manual mechanical process of subjective assessment with an automated computer-based system that processes angiographic images to objectively determine SYNTAX Score parameters, eliminating human variability and reducing time consumption while maintaining clinical accuracy

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service by allowing the computer to automatically calculate the SYNTAX Score without requiring manual intervention from clinicians, thereby reducing the time burden on healthcare providers while ensuring consistent application of scoring criteria

Inventive Principle:
Principle #25Self-service

2Productivity

If automated image analysis is implemented, then time consumption is reduced and objectivity is improved, but the system complexity increases

Engineering Contradiction:
Improvespeed of score calculationVSAvoidcomplexity of automated system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements a multi-functional system that can process various types of angiographic images, calculate multiple SYNTAX Score parameters, and provide comprehensive decision-support information, thereby achieving high productivity through a single integrated automated platform despite increased complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If detailed vascular metrics are automatically determined, then measurement precision is improved, but the complexity of the analysis process increases

AI summary

Automated image analysis used in vascular disease characterization. Coronary vas-culature in particular is automatically characterized in some embodiments for lesion complexity and related anatomical and/or functional parameters related to disease state. In some embodiments, a "virtual revascularization" model is used as a reference in disease state determinations. In some embodiments, disease parameters are determined for application by a disease characterization tool such as a SYNTAX Score calculator.
