Catheter Complication Risk Scoring via Similar Case Retrieval

The patent transforms the complication risk assessment from simple distance-based evaluation to a multi-parameter scoring system. It calculates scores based on multiple parameters including distance from prosthetic valve to peripheral tissue, angle of peripheral tissue, and other anatomical features. This parameter transformation enables more accurate risk assessment while maintaining computational efficiency through structured scoring algorithms.

The patent creates a composite evaluation model that integrates multiple assessment dimensions (distance, angle, anatomical structure, patient-specific factors) into a unified complication risk score. This composite approach combines various parameters weighted by their clinical significance, producing a comprehensive risk assessment that is both accurate and clinically actionable.

The patent segments the complication risk assessment into distinct modules: data acquisition module, score calculation module for each complication type, risk identification module, and similar case retrieval module. Each module handles specific tasks independently, processing different aspects of medical information separately before integrating results. This segmentation reduces system complexity while maintaining comprehensive analysis capabilities.

The patent introduces a scoring system as an intermediary that transforms complex multi-dimensional medical information into standardized numerical scores. This intermediary layer simplifies the processing of diverse medical data by converting it into comparable metric forms, enabling systematic analysis without requiring direct complex processing of all raw medical information simultaneously.

The patent performs preliminary organization and indexing of historical complication cases during data storage, structuring them by complication type, score ranges, and key anatomical parameters. This preliminary action enables efficient retrieval operations by pre-processing the data into searchable formats, reducing the time required for similar case matching while maintaining comprehensive comparison capabilities.

The patent implements selective retrieval of similar cases based on the specific complication being assessed, retrieving only relevant historical cases that match the current assessment context. Rather than comparing against all historical data, the system focuses on locally relevant cases with similar anatomical features and complication types, reducing retrieval time while maintaining assessment reliability.
