Abstract

Mechanical forces and strain induced by tran-scatheter aortic valve implantation are usually named as origins for postoperative left ventricular arrhythmia associated with the technique. No quantitative data has been published so far to substantiate this common belief. As a first step towards quantitative analysis of the biomechanic situation at the aortic root after transapical aortic valve implantation, we present a spline-based method for reconstruction of the implanted stent from CT images and for locally measuring the deformation of the stent.
