Heart Valve Topology Mapping for Accurate Morphology Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to accurately visualize and assess the morphology of heart valves, particularly the tricuspid valve, due to its concealed position and movement, making surgical planning and implant procedures challenging.
Innovation Solution
A computer-implemented method that creates a topology-based 2D model of a heart valve from a 3D or 4D volume data set, allowing users to adjust and edit the morphology intuitively using a user interface, with features like a digital joystick and valve dashboard for enhanced visualization and planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a 3D or 4D volume data set is used to visualize heart valve morphology, then the anatomical structure can be captured in detail, but the visualization becomes complex and difficult to interpret due to the concealed arrangement and movement of the valve
Solution Approach 1:
The patent segments the heart valve into distinct anatomical components (annulus, leaflets, commissures) and represents them in a simplified 2D topological model. This segmentation allows complex 3D/4D data to be broken down into manageable, interpretable elements while preserving essential morphological information for surgical planning.
Solution Approach 2:
The patent transforms three-dimensional and four-dimensional volume data into a two-dimensional topological representation. This dimensional reduction simplifies the visualization by projecting complex spatial relationships onto a 2D plane, making the valve morphology easier to interpret while maintaining topological accuracy for surgical intervention planning.
2Reliability
If the heart valve is visualized in its natural 3D position within the body, then anatomical context is preserved, but the valve becomes hard to visualize due to its concealed position and movement during the heart cycle
Solution Approach 1:
The patent extracts the heart valve from its concealed position within the 3D/4D volume data set and presents it as a isolated 2D topological model. This extraction removes the confounding context of the valve's position within the heart and its movement during the cardiac cycle, allowing for reliable and easy assessment of valve morphology without the interference of physiological motion.
Solution Approach 2:
The patent creates a simplified 2D topological copy or representation of the 3D/4D heart valve data. This copy captures the essential topological features (annulus shape, leaflet arrangements, commissure positions) while eliminating the complexity of the original 3D/4D visualization, making the valve morphology accessible and easy to assess for surgical planning.
3Measurement precision
If anatomical landmarks are marked directly on the moving 4D clip, then the valve morphology can be assessed, but the landmarks are not intuitive to mark and are hard to edit
Solution Approach 1:
The patent provides a 2D topological interface for marking anatomical landmarks, which is more intuitive and easier to edit than marking on 3D/4D data. The 2D representation allows users to easily identify and edit landmark positions (annulus perimeter, leaflet tips, commissures) without the complexity of spatial coordinates and temporal framing required in 3D/4D space.
Solution Approach 2:
The 2D topological model serves as an intermediary between the raw 3D/4D imaging data and the surgical planning process. It provides a user-friendly interface for annotating and editing anatomical landmarks, translating complex spatial and temporal information into a simplified representation that is easy to mark and modify, while still accurately reflecting the valve morphology.
