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 کاملPerceval Sutureless Valve – are Sutureless Valves Here?
With the advent of transcatheter aortic valve implantation (TAVI) techniques, a renewed interest has developed in sutureless aortic valve concepts in the last decade. The main feature of sutureless aortic valve implantation is the speed of insertion, thus making implantation easier for the surgeon. As a result, cross clamp times and myocardial ischemia may be reduced. The combined procedures (C...
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 کاملSubclinical Valve Thrombosis in Sutureless Bioprosthetic Valves
I n the current issue of JAHA, Dal en et al 1 report the results of a single-center prospective observational study of 47 patients with implantation of the Perceval sutureless bioprosthesis (LivaNova, Milan, Italy). Cardiac computed tomography (CT) performed at a median of 491 days (range 36– 1247 days) found hypo-attenuated leaflet thickening (HALT) in 18 (38%) and reduced leaflet motion (RLM)...
