Paravalvular sealing pf percutaneous heart valves
… “NF” and Back Flow Filling “BFF”) using a pulse duplicator fitted with perforated mounting rings. Optimization of solution, process and environmental parameters yielded scaffolds with average fibre diameters of 3.17 ± 0.64 μm and average pore sizes 9.52 ± 6.90 μm. Tensile strength was found …

In silico and in vitro analysis of calcific and rheumatic aortic stenosis
… in vitro experimental data using a cardiac pulse duplicator (CPD) system designed in accordance with ISO 5840 for in vitro testing of heart valve prostheses. The results show that the simplified Bernoulli equation both over- and underestimates the TPG depending on the type and severity of …

Stents for transcatheter aortic valve replacement
… evaluated through in vitro haemodynamics in a pulse duplicator and durability was tested in a high-cycle fatigue tester. Simulated use testing was performed using cadaveric animal hearts. Finally, valves were also implanted into the aortic valve position of pigs (in acute termination …

Development of a Tubular Biological Tissue-Engineered Heart Valve with Growth Potential
This thesis investigates tissue-engineered cardiovascular devices for pediatric patients and their function and growth potential in preclinical testing. Specifically, engineered tissue tubes were fabricated by entrapping dermal fibroblasts in a fibrin gel and allowing them to replace it with …
