Implication

Feasibility of CT-based TAVI radial force estimation shown in most cases; leaves open clinical utility pending prospective validation.

Population

21 patients who underwent transcatheter aortic valve implantation (TAVI) and synthetic test cases

Intervention

Image-based mechanical analysis of stent deformation using CT images and finite-element modeling

Outcome

Extraction of radial force load and geometric error of stent reconstructionsurrogate

A novel image-based mechanical analysis approach successfully estimates in vivo radial forces of TAVI stents from CT images, which may help improve stent design and understand complication mechanisms.

Limitations

Uncertainty in the quantitative evaluation of radial forces due to uncertainty in defining a radial direction on the deformed stent
