Mechanical Heart Valves in Children
Scandinavian Journal of Thoracic and Cardiovascular Surgery, 1984Longterm follow-up of 17 children, who consecutively underwent replacement of one cardiac valve with the Björk-Shiley prosthesis, is presented. The children's mean age was 8 years (range 4-12 years) and body weight 23.5 kg (range 15.0-38.4 kg) at the time of surgery 1970-80. Nine of the 17 operations (53%) were second-stage cardiac surgery.

Fluid Mechanics of Heart Valves
Annual Review of Biomedical Engineering, 2004▪ Abstract Valvular heart disease is a life-threatening disease that afflicts millions of people worldwide and leads to approximately 250,000 valve repairs and/or replacements each year. Malfunction of a native valve impairs its efficient fluid mechanic/hemodynamic performance.

Mechanisms of Expiratory Valves Resistance
American Review of Respiratory Disease, 1988Expiratory valves are the major source of resistance in ventilator circuits. Some valves, particularly under certain conditions, cause high resistances. To establish the mechanisms of expiratory valve resistance (R), we measured R of 4 commercial valves under several experimental conditions.

Mechanical Heart Valves in Septuagenarians
Journal of Cardiac Surgery, 2008To report on the use of a third-generation bileaflet mechanical valve in septuagenarians, selected to receive a mechanical valve, as compared to (a) a younger cohort undergoing same valve implant (study 1) and to (b) a matched group of septuagenarians undergoing biological implant (study 2).The study was carried out in a tertiary regional hospital in ...

Mechanisms of aortic valve calcification
The American Journal of Cardiology, 2004The calcified aortic valve lesion develops in the setting of endothelial injury and inflammation and displays hallmarks of atherosclerosis, including lipids accumulation, matrix metalloproteinase activation, and interaction with renin-angiotensin system.
