How to Assess the Aortic Valve to Plan for a TAVI Procedure

Transcatheter procedures are transforming the treatment of heart valve conditions, particularly with regards to aortic valve stenosis. To assess whether a patient is a good candidate for a transcatheter aortic valve implantation (TAVI), imaging and several measurements need to be performed. 

The Mimics Innovation Suite can play an important role in assessing a candidate’s compatibility for TAVI. This tutorial covers several workflows that can help to plan a TAVI case. In a first stage, we perform the digital segmentation of the heart chambers and the greater vessels, using a semi-automated tool. As we are working on a TAVI case, the valve is heavily calcified; we extract the calcifications and improve the segmentation of the aortic leaflets.
