Ideal Navitor Implant Depth for Redo-TAVR Feasibility and Coronary Access: A Computed Tomography (CT) Simulation Study
Authors' conclusion
In our CT simulation study, redo-TAVR and coronary access were predicted to be the most favorable with initial Navitor implant depth of 3 mm and redo-S3 implanted lower at Node 2. In vivo analysis will help confirm these findings.
Study context
- Population
- Patients with native aortic stenosis with pre-TAVR CTs
- Participants
- 2,050 pre-TAVR CTs
- Comparison
- Redo-TAVR and coronary access with S3 after initial Navitor valve, based on various implant depths
- Outcome
- Redo-TAVR unfeasible
Main finding
As reported in the abstract
P < 0.0001
Further findings
Coronary access
- Least challenging with initial Navitor depth at 3 mm and redo-S3 implanted lower at Node 2
- P < 0.0001
Results by Navitor valve size
- Results similar across all Navitor valve sizes
Commissural alignment in Navitor
- Improved redo-TAVR feasibility only when implanted at 5 mm
