Why the study?

MSCT analysis, the gold standard for ViV-TAVI pre-procedural planning, has limitations that virtual reality delivering 3D patient-specific information might optimize.

Does virtual reality software provide accurate measurements and improve pre-procedural planning for valve-in-valve TAVI compared to standard MSCT analysis?

Population

MSCT data from 20 patients who underwent ViV-TAVI interventions

Comparison

VR software vs 3mensio software

Design

Blinded comparative imaging analysis study

Key result

Virtual reality visualization for ViV-TAVI planning yielded measurements highly correlated with standard software (r=0.874-0.994, P<0.001) and improved spatial understanding of adjacent structures.

Structured PICO

Does virtual reality software provide accurate measurements and improve pre-procedural planning for valve-in-valve TAVI compared to standard MSCT analysis?

P
Population
20 patients who underwent ViV-TAVI interventions whose MSCT data was used to compare virtual reality and standard software measurements.
E
Exposure
Pre-procedural planning using virtual reality (VR) software for 3D visualization of the bioprosthesis and adjacent structures.
C
Comparator
Standard pre-procedural planning using 3mensio software based on MSCT data.
O
Outcome
Feasibility of visualizing the bioprosthesis and adjacent structures, accuracy and reproducibility of VR measurements, and qualitative assessment of planning advantages and limitations.surrogate

Main Result

Effect estimate: correlation coefficients 0.874 to 0.994

p-value: p=< 0.001

Virtual reality provides accurate, reproducible measurements and superior 3D visualization for pre-procedural planning of valve-in-valve TAVI compared to standard MSCT analysis.

Limitations

  • Further studies are needed to assess the impact on patient outcomes

Kanschik et al. (2025) conducted an observational in Degenerated surgical bioprosthetic aortic valves requiring ViV-TAVI (n=20). Virtual reality (VR) visualization vs. 3mensio software (standard MSCT analysis) was evaluated on Accuracy and reproducibility of measurements (correlation between VR and 3mensio software) (correlation coefficients 0.874 to 0.994, p=< 0.001). Virtual reality visualization for ViV-TAVI planning yielded measurements highly correlated with standard software (r=0.874-0.994, P<0.001) and improved spatial understanding of adjacent structures.
