Impact of Virtual Reality on Transcatheter Aortic Valve Implantation: A Prospective Randomized Controlled Trial
- randomized, prospective, controlled study
- single-centre (University Hospital Duesseldorf)
Authors' conclusion
The data show that virtual reality visualization can optimize preparation for the procedure by improving the 3-dimensional understanding of the aortic valve and adjacent structures. The detailed visualization of the access routes can lead to a reduction in periprocedural complications.
Study context
- Population
- Patients who underwent transcatheter aortic valve implantation at the University Hospital Duesseldorf between April and August 2024
- Participants
- 140 patients
- Comparison
- Virtual reality (VR)-supplemented preprocedural planning vs 3mensio software alone
Primary result
As reported in the abstract
- No relevant differences in patient characteristics
Further findings
3-dimensional understanding (interventionalist questionnaire)
- VR superior to 3mensio software
- P < 0.001
Depth perception, visualization of atherosclerotic plaques, iliofemoral tortuosity
- Better in the VR group
Usefulness in preparing for the procedure
- Both methods found useful and helpful
Procedural data
- No significant differences between the 2 groups
Length of hospital stay and postprocedural transthoracic echocardiography data
- No significant difference
Safety
Bleeding at the access site
- Lower rate in the VR group
- P < 0.05
