Abstract This study aims to develop a system based on mixed reality imaging for assistance in percutaneous ultrasound‐guided liver interventions. A phantom, an ultrasound scanner with abdominal probe, electromagnetic tracking localization of the and needle were used system. gelatin phantom was fabricated, including set lesions (with agarose, glycerol, sephadex) artificial blood vessels 3D printed thermoplastic polyurethane (TPU) elastic fibres. Intraoperative images from BK5000 acquired using video capture transmitted Slicer. The NDI Aurora system, coupled probe intracorporeal needle, real‐time trajectory tracking, providing us spatial information. These are then sent augmented HoloLens device as primary visualization work lays groundwork development more comprehensive assist interventions order improve accuracy safety these procedures. use technology allows better integration image‐guided surgery systems, such one presented this work, real clinical environments, closer patient.

Background: Rheumatic heart disease (RHD) remains a major health challenge in Africa, where the prevalence is notably high. Valvular surgery crucial procedure for managing severe RHD. However, current state and historical trend of research on this subject African populations not well understood. Understanding scope, matter, quality literature topic over time essential to inform future clinical practice. Objective: This paper aims assess published evaluate vital outcomes such as surgical outcomes, survival rates, postoperative complications, long-term life, morbidities, mortalities, barriers valve patients with RHD Africa. Methods: protocol adheres Preferred Reporting Items Systematic Reviews Meta-Analyses extension Scoping (PRISMA-ScR). An extensive search will be conducted across different databases, including PubMed, Scopus, Web Science, Cochrane Library, Index Medicus, Journals Online. Studies identified through keyword searches reviewed against predefined inclusion exclusion criteria by two reviewers, third reviewer resolving any discrepancies. A narrative synthesis describe findings. Conclusion: The findings from scoping review provide an understanding valvular contexts. help guide directions field.
