Abstract
Background: The rise of transcatheter tricuspid valve implantation (TTVI) therapies represents a major advancement for high-risk patients with severe tricuspid valve regurgitation, offering a safer, minimally invasive alternative to open-heart surgery. However, the low volume of procedures and training highlights an urgent need for skills development and pre-procedural preparation, which simulation can address by enhancing learning and expanding treatment availability. Case summary: An 87-year-old woman with permanent atrial fibrillation and symptomatic severe functional tricuspid regurgitation underwent a transcatheter tricuspid valve replacement with the LuX-Valve system. We developed a novel patient-specific virtual reality simulator, combining virtual and physical simulations, to enhance training and education for TTVI. This system utilizes high-resolution computed tomography images, machine learning algorithms, and a video game engine to recreate realistic procedural environments. We performed a safe intervention following the simulation session, achieving successful clinical outcomes in the patient. Discussion: The developed platform is the first to propose a patient-specific hybrid simulation for TTVI engaging both interventional and imaging cardiologists. The simulator's potential to improve clinical and safety outcomes warrants further evaluation through specifically designed comparative studies.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
