Comparative study of wall shear stress at the ascending aorta for different mechanical heart valve prostheses [PDF]
, 2019 An experimental study is reported which investigates the wall shear stress (WSS) distribution in a transparent model of the human aorta comparing a bileaflet mechanical heart valve (BMHV) with a trileaflet mechanical heart valve (TMHV) in physiological ...

The Journal of Thoracic and Cardiovascular Surgery, 1965 SUMMARY This paper summarizes the experience in the treatment of a series of 1,370 cases of open-heart surgery. Of these, 964 valvular lesions and the associated pathologic lesion are analyzed. Details of correction and immediate and late results in the treatment of the following groups of lesions were studied: 74 cases of congenital aortic stenosis ...

Biologically Inspired Scaffolds for Heart Valve Tissue Engineering via Melt Electrowriting.
Small, 2019 Heart valves are characterized to be highly flexible yet tough, and exhibit complex deformation characteristics such as nonlinearity, anisotropy, and viscoelasticity, which are, at best, only partially recapitulated in scaffolds for heart valve tissue ...
