Assessment of aortic valve tract dynamics using automatic tracking of 3D transe...
Queirós, Sandro; Morais, Pedro; Fehske, Wolfgang; Papachristidis, Alexandros; Voigt, Jens-Uwe; Fonseca, Jaime C.; D'hooge, Jan; Vilaça, João L.The assessment of aortic valve (AV) morphology is paramount for planning transcatheter AV implantation (TAVI). Nowadays, pre-TAVI sizing is routinely performed at one cardiac phase only, usually at mid-systole. Nonetheless, the AV is a dynamic structure that undergoes changes in size and shape throughout the cardiac cycle, which may be relevant for prosthesis selection. Thus, the aim of this study was to presen...

Non-invasive myocardial performance mapping using 3D echocardiographic stress-s...
Pedrosa, João; Duchenne, Jürgen; Queirós, Sandro Filipe Monteiro; Degtiarova, Ganna; Gheysens, Olivier; Claus, Piet; Voigt, Jens-Uwe; D'hooge, JanRegional contribution to left ventricular (LV) ejection is of much clinical importance but its assessment is notably challenging. While deformation imaging is often used, this does not take into account loading conditions. Recently, a method for intraventricular pressure estimation was proposed, thus allowing for loading conditions to be taken into account in a non-invasive way. In this work, a method for 3D au...
Validation of a Novel Software Tool for Automatic Aortic Annular Sizing in Thre...
Queirós, Sandro; Morais, Pedro; Dubois, Christophe; Voigt, Jens-Uwe; Fehske, Wolfgang; Kuhn, Andreas; Achenbach, Tobias; Fonseca, Jaime; Vilaça, JoãoBackground: Accurate aortic annulus (AoA) sizing is crucial for transcatheter aortic valve implantation planning. Three-dimensional (3D) transesophageal echocardiography (TEE) is a viable alternative to the standard multidetector row computed tomography (MDCT) for such assessment, with few automatic software solutions available. The aim of this study was to present and evaluate a novel software tool for automat...
