Mixed Reality in MitraClip Implantation: Preliminary Case Series

Recruiting
Conditions
Mitral Regurgitation
Interventions
Procedure: MitraClip implantation
Registration Number
NCT06539416
Lead Sponsor
Nemocnice AGEL Trinec-Podlesi a.s.
Brief Summary

The study aims to evaluate the impact of mixed reality (MR) technology, particularly using Hololens 2.0 and specialized software for three-dimensional DICOM image visualization, on MitraClip implantation procedures. This preliminary case series includes a comparative analysis of four MitraClip implantations, assessing procedural efficiency, radiation exposure, and operator stress through both physiological and subjective measures.

Detailed Description

The advent of mixed reality (MR) technology, especially when integrated with Hololens 2.0 and specialized software for three-dimensional DICOM image visualization, offers promising avenues for enhancing precision and spatial awareness in interventional cardiology procedures. This case series aims to preliminarily evaluate the impact of MR on MitraClip implantation processes, setting the foundation for a comprehensive pilot study.
