Autor: Thomas Schmitz-Rode, Ulrich Steinseifer, Buntaro Fujita, Sandrine Egron, Lucía Gullón, Stephan Ensminger, Desiree Pott
Publikováno v: ASAIO Journal. 64:536-543
The goal is to inform in depth on transcatheter aortic valve replacement (TAVR) prosthesis mechanical behavior, depending on frame type, design, and size, and how it crucially impacts the oversizing issue in clinical use, and ultimately the procedure

Fluid-structure interaction of a pulsatile flow with an aortic valve model: A combined experimental and numerical study
Autor: Julien, Sigüenza, Desiree, Pott, Simon, Mendez, Simon J, Sonntag, Tim A S, Kaufmann, Ulrich, Steinseifer, Franck, Nicoud
Publikováno v: International journal for numerical methods in biomedical engineering. 34(4)
The complex fluid-structure interaction problem associated with the flow of blood through a heart valve with flexible leaflets is investigated both experimentally and numerically. In the experimental test rig, a pulse duplicator generates a pulsatile

Publikováno v: Zeitschrift für Herz-,Thorax- und Gefäßchirurgie. 27:361-365
Die Trikuspidalklappeninsuffizienz tritt am haufigsten aufgrund einer Dilatation des rechten Ventrikels, sekundar nach linksseitigen Herzerkrankungen, auf. Bis vor Kurzem wurde der Entwicklung von perkutanen Trikuspidalklappenprothesen wenig Aufmerks

Simplified multistage computational approach to assess the fatigue behavior of a niti transcatheter aortic valve during in vitro tests: A proof-of-concept study
Autor: Elena Dordoni, Maximilian Kütting, Dario Allegretti, Francesco Migliavacca, Lorenza Petrini, Giancarlo Pennati, Desiree Pott
Nowadays, transcatheter aortic valve (TAV) replacement is an alternative to surgical therapy in selected high risk patients for the treatment of aortic stenosis. However, left ventricular contraction determines a severe cyclic loading for the implant
