Patient-specific mixed reality for venus P-valve implantation: A novel approach to procedural planning

This study assesses the use of mixed reality (MxR) technology for procedural planning in transcatheter pulmonary valve implantation (TPVI) with the Venus P-Valve. Holographic models were created from CT data to aid in valve sizing and implantation strategies, with two operators comparing measurements for valve diameter and length. Among 26 patients who underwent successful implantation, concordance between operators was 60 % for valve diameter and 88 % for valve length. Predictions using holographic models showed 96 % concordance for implanted valve length, type of the approach (92 %) and 50 % concordance for valve diameter. These results highlight the potential of MxR for improving TPVI planning, though the limited accuracy for valve diameter suggests a need for further advancements, such as computational modeling or machine learning, to optimize procedural outcomes in interventional cardiology.
