A 55-year-old invasive/clinical cardiologist worked full time, exercised regularly, and was asymptomatic. Two weeks previously, he had new onset of angina on exertion. Echocardiography/Doppler and cardiac catheterization confirmed the clinical assessment of severe aortic stenosis with a valve area of 0.5 cm2/m2.

Design and Fabrication of Three-Dimensional Scaffolds for Tissue Engineering of Human Heart Valves [PDF]
We developed a new fabrication technique for 3-dimensional scaffolds for tissue engineering of human heart valve tissue. A human aortic homograft was scanned with an X-ray computer tomograph.

Dynamic Views of Structure and Function during Heart Morphogenesis [PDF]
Congenital heart defects remain the most common birth defect in humans, occurring in over 1% of live births. The high prevalence of cardiac malformations can be partially attributed to limited knowledge regarding the embryonic roots of the disease.

The living aortic valve: From molecules to function. [PDF]
The aortic valve lies in a unique hemodynamic environment, one characterized by a range of stresses (shear stress, bending forces, loading forces and strain) that vary in intensity and direction throughout the cardiac cycle.

Guided Tissue Regeneration in Heart Valve Replacement: From Preclinical Research to First-in-Human Trials [PDF]
Heart valve tissue-guided regeneration aims to offer a functional and viable alternative to current prosthetic replacements. Not requiring previous cell seeding and conditioning in bioreactors, such exceptional tissue engineering approach is a very ...

Comparative study of wall shear stress at the ascending aorta for different mechanical heart valve prostheses [PDF]
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 ...

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 ...
