Novel nitinol, self-expandable, short bodied transcatheter aortic valve implantation (TAVI) prostheses allow for magnetic resonance imaging (MRI)-based evaluation of the left ventricle and aortic root, due to a relatively small susceptibility artefact. We have employed four dimensional (4D-)flow MRI-analysis in 3 patients, 2 years after uncomplicated TAVI with the new CENTERA prosthesis. Thoracic 4D flow MRI was conducted at 3.0T with a spatial and temporal resolution of 2.5 mm3 and ± 42 milliseconds. Vortex formation in the three sinuses of Valsalva was analyzed using advanced streamline techniques.
