Adult cardiac & structural heart: Are VR measurements as accurate as CT planning software for TAVI?

Name: Adult cardiac & structural heart: TAVI measurement accuracy in VR and AR surgical planning
Creator: Realize Medical

6 Adult cardiac & structural heart studies in the library address this question.

What the studies report

Positive finding
“The analysis showed no significant differences between the measurements and strong correlations with correlation coefficients between 0.874 and 0.994, P < 0.001.”
Kanschik 2025 · Validation study · n: 20 patients
Positive finding
“The intraclass correlation coefficient (ICC) confirmed excellent consistency for annular measurements (ICC = 0.93), while the concordance correlation coefficient indicated very good overall agreement (CCC = 0.83, 95% CI 0.73-0.90).”
Carabetta 2025 · Validation study · n: 50 patients
Positive finding
“There were no significant differences but strong correlations between the VR measurements compared with those performed with the 3mensio software.”
Kanschik 2024 · Validation study · n: 60 patients
Positive finding
“Virtual reality visualization of the left atrium and appendage based on MSCT data is feasible and allows precise and reproducible measurements in planning of LAA occlusion procedures with enhanced 3D orientation.”
Heidari 2023 · Validation study · n: 21 patients
