Fig. 2

Three-dimensional model of a single frame from all markers. Cylindrical markers were manually separated from ball markers, thus allowing to distinguish right heart (red dots) from left heart (blue dots) markers (a). Using video loops constructed of all recorded frames allowed identification of the fast moving leaflet marker (green dot, a). Afterwards tricuspid annular, leaflet, as well as right and left ventricular markers were identified and connected with virtual lines (tricuspid annulus: red line, right ventricle: red dotted line, left ventricle: blue dashed line) using a Matlab visualization tool (b, c). LV left ventricle
