Background
- Trans-catheter aortic valve implantation/replacement (TAVI/TAVR)
- Treatment for aortic stenosis (further information)
- Current treatment is sutureless valve inflation (balloon or nitinol) using fluoroscopy/angiography guidance
Proposed research
- We are interested in investigating the use of magnetically tracked ultrasound image guidance for procedure guidance
Key Investigators
- Adam Rankin
- Dr. Terry Peters, supervisor
- Dr. Gabor Fichtinger, supervisor
Project Description
Objective
- Continue work on TAVI workflow in a series of Slicer modules
- Module to guide valve holder tool to aortic annulus (depth analysis, tool orientation analysis, etc...)
- Module to facilitate ideal bi-plane orientation from tracked 3D data
- Current source available at (SlicerTAVI)
Questions
- 3D probe calibration (possible rigid transformation from 2D calibration)
- Magnetic tracking in OR not necessarily feasible
- Cardiac surgeons involved express reluctance to give up fluoro (suprise...) so possible generate synthetic fluoro pre-op CT and intra-op US
Approach, Plan
- Develop phase 1 module with magnetic tracking to show feasibility of magnetic solution
- Phase 2 module might include image based tracking, US emitter based tracking, or other solutions suggested by intelligent and good-looking Slicer community
Progress
- Receive feedback from Tina regarding quality of initial project page
- Modules already started, basic workflow implemented, lots of details remain to be implemented
