Artificial Heart Valves
The cardiovascular system is a closed circulatory system that ensures blood flow through the human body. Blood circulates through two systems; the first is responsible for pushing blood from the heart to the lungs to capture oxygen, and the second is responsible for distributing oxygenated blood to body organs. This system is composed of a double pump with branched tubes that leads blood from t...
متن کاملFluid mechanics of artificial heart valves.
1. Artificial heart valves have been in use for over five decades to replace diseased heart valves. Since the first heart valve replacement performed with a caged-ball valve, more than 50 valve designs have been developed, differing principally in valve geometry, number of leaflets and material. To date, all artificial heart valves are plagued with complications associated with haemolysis, coag...
متن کاملAcute failure of artificial heart valves.
acute myocardial infarctions has shown that 160 mg aspirin daily reduces mortality after five weeks by a fifth.9 Despite the lack of evidence from clinical trials many patients with transient ischaemic attack and stroke are treated with 75 mg daily (a dose enshrined in the current British National Formulary), with the risk that they may be receiving an inadequate dose, albeit a safe one. On the...
متن کاملAdvances and Trends in Tissue Engineering of Heart Valves
Improvements in health care and treatment of diseases have led to an increase in life expectancy in developed countries. However, this achievement has also inadvertently increased the prevalence of chronic illnesses such as cardiovascular disease, adding to the growing burden of health care cost globally. Unfortunately, this trend is expected to escalate in the foreseeable future. Cardiovascula...
متن کاملTissue engineering of heart valves: in vitro experiences.
BACKGROUND Tissue engineering is a new approach, whereby techniques are being developed to transplant autologous cells onto biodegradable scaffolds to ultimately form new functional tissue in vitro and in vivo. Our laboratory has focused on the tissue engineering of heart valves, and we have fabricated a trileaflet heart valve scaffold from a biodegradable polymer, a polyhydroxyalkanoate. In th...
