用于经导管肺动脉瓣置换术的四维计算机断层扫描引导的瓣膜尺寸

Executive Industry Relevance

Dynamic 4D cardiac CT-guided valve sizing addresses a critical challenge in transcatheter pulmonary valve replacement (TPVR) by enabling precise, quantitative assessment of right ventricular outflow tract (RVOT) and pulmonary artery (PA) anatomy throughout the cardiac cycle. This approach enhances predictive confidence in device selection, reducing the risk of stent misplacement and paravalvular leak, and supports innovation in device design and procedural planning. Integrating 4D modeling into the discovery-to-preclinical continuum strengthens translational continuity and portfolio decision-making for structural heart interventions.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables quantitative interrogation of RVOT and PA dynamics for functional target validation in device development.
• Supports mechanistic de-risking by visualizing anatomical deformation across the cardiac cycle.
• Improves predictive confidence in device fit and performance, informing early go/no-go decisions.

Screening & Assay Development

• Facilitates preparation of validated anatomical models for device sizing and simulation workflows.
• Standardizes measurement of diameter, area, and circumference across multiple cardiac phases.
• Enables reproducible, quantitative outputs for comparative device evaluation and screening.

Translational & Preclinical Research

• Aligns device sizing with disease-relevant, dynamic anatomical models for translational continuity.
• Supports risk-adjusted advancement by providing robust, quantitative endpoints for preclinical validation.
• Enhances predictive de-risking for device performance in physiologically relevant systems.
