A Biomechanical and Microstructural Analysis of Bovine and Porcine Pericardium for Use in Bioprosthetic Heart Valves
Murphy, Bruce (2021)Background: Animal-derived pericardium is a key material that enables the successful clinical use of bioprosthetic heart valves. Recently, transcatheter heart valves have placed more emphasis on the enhancement of this ... -
Bovine pericardium of high fibre dispersion has high fatigue life and increased collagen content; potentially an untapped source of heart valve leaflet tissue
Whelan, Alison; Murphy, Bruce; Lally, Caitriona (2020)Bioprosthetic heart valves (BHVs) are implanted in aortic valve stenosis patients to replace the native, dysfunctional valve. Yet, the long-term performance of the glutaraldehyde-fixed bovine pericardium (GLBP) leaflets ... -
Collagen fibre orientation and dispersion govern ultimate tensile strength, stiffness and the fatigue performance of bovine pericardium
Whelan, Alison; Lally, Caitriona; Murphy, Bruce (2019)The durability of bovine pericardium leaflets employed in bioprosthetic heart valves (BHVs) can significantly limit the longevity of heart valve prostheses. Collagen fibres are the dominant load bearing component of bovine ...
