Modular aortic valve prosthesis for transcatheter aortic valve implantation: a novel concept with a new implantation method

Abstract

Transcatheter aortic valve implantation (TAVI) is a relatively new medical intervention. Research on dedicated TAVI devices is an exciting and dynamic field to be explored by professionals involved in technological innovation. The authors describe in this article the first engineering concept and part of the US Patent of a new valve prosthesis. Divided into two pieces to be separately implanted using a single catheter by means of an innovative technique, this device aims at reducing prosthesis and delivery catheter profile. Miniaturization of the valve and delivery system is probably the best solution to reduce the morbidity and mortality that derive from vascular complications associated with TAVI.

Automatic aortic root segmentation and anatomical landmarks detection for TAVI procedure planning

“…This step is of high importance because of the recent development of a large set of available valve prosthesis (e.g. [25]). A clinical study is currently under consideration to evaluate the time and accuracy obtained with/without the use of this automatic pipeline.…”
