Key result

Immersive 3D virtual reality shows excellent consistency with standard CT, improving TAVI prosthesis sizing accuracy.

Why the study?

Accurate anatomical assessment is essential for pre-procedural planning in structural heart disease, and advanced 3D imaging could offer improved visualization for more accurate reconstruction.

Does immersive 3D virtual reality (VEA) improve the accuracy of pre-procedural anatomical assessment and prosthesis sizing compared to standard CT analysis in TAVI candidates?

Population

50 consecutive TAVI candidates

Comparison

Novel immersive 3D virtual reality (VEA) vs established tools (3Mensio and Horos)

Design

Validation study using cardiac-gated contrast-enhanced CT scans

Implication

Supports VEA for TAVI prosthesis selection in practice; extends evidence for immersive VR as reliable CT adjunct.

Key Points

The study aims to validate the effectiveness of immersive virtual reality for planning TAVI by comparing it with traditional imaging methods.
Measured cardiac-gated contrast-enhanced CT scans using virtual reality and established tools.
Included 50 consecutive TAVI candidates for assessment.
Evaluated correlation and consistency of measurements between VEA and standard CT analysis.
VEA measurements for annular and LVOT showed strong correlation with CT results (ICC of 0.93 and 0.90, respectively).
Concordance correlation coefficients indicated very good agreement for annular measurements (CCC=0.83) and good consistency for LVOT (CCC=0.77).
VEA improved accuracy in prosthesis size selection, demonstrating a significant net reclassification gain over conventional CT.

Structured PICO

Does immersive 3D virtual reality (VEA) improve the accuracy of pre-procedural anatomical assessment and prosthesis sizing compared to standard CT analysis in TAVI candidates?

Population

50 consecutive patients who are candidates for transcatheter aortic valve implantation (TAVI)

Intervention

Novel immersive 3D virtual reality (VEA) for measurement of cardiac-gated contrast-enhanced CT scans

Comparator

Established tools (3Mensio and Horos) for standard CT analysis

Outcome

Consistency and agreement of annular and LVOT measurementssurrogate

Immersive 3D virtual reality (VEA) provides reliable aortic root measurements and improves prosthesis size selection accuracy for TAVI planning compared to conventional CT.
