An artificial heart is a device that replaces the heart. Artificial hearts are typically used to bridge the time to heart transplantation, or to permanently replace the heart in case heart transplantation is impossible.]]> 2016-10-16 14:08:17 UTC https://padlet.com/10025026/lspbk894qb7j/wish/130970213 10025026 https://padlet.com/10025026/lspbk894qb7j/wish/130970376 Constructing a machine that can withstand the human circulatory system and can pump 35 million times a year is quite difficult. ]]> 2016-10-16 14:10:56 UTC https://padlet.com/10025026/lspbk894qb7j/wish/130970376 10025026 https://padlet.com/10025026/lspbk894qb7j/wish/130970578 An artificial heart or LVAD is made out of metal, plastic, ceramic, and animal parts. A titanium-aluminum-vanadium alloy is used for the pump and other metal parts because it is biocompatible and has suitable structural properties. The titanium parts are cast at a specialized titanium processor. Except for blood-contacting surfaces, the titanium is machined to a specific finish. Blood-contacting surfaces receive a special coating of titanium microspheres that bond permanently to the surface. With this coating, blood cells adhere to the surface, creating a living lining. 

A blood-contacting diaphragm within the pump is made from a special type of polyurethane that is also textured to provide blood cell adherence. Two tubular grafts are made from polyester (which are used to attach the device to the aorta) and the valves are actual heart valves removed from a pig. Other parts that make up the motor are made from titanium or other metals and ceramics. ]]> 2016-10-16 14:14:13 UTC https://padlet.com/10025026/lspbk894qb7j/wish/130970578 10025026 https://padlet.com/10025026/lspbk894qb7j/wish/130970651 Is expected to cost $193,600 each. 
Every year more than 100,000 people await a heart transplant, with generally fewer than 4,000 hearts available. If these bio prosthetic hearts are proven to be effective, patients could use these for years as they wait for a transplant and continue their lives in the meantime.]]> 2016-10-16 14:15:35 UTC https://padlet.com/10025026/lspbk894qb7j/wish/130970651 10025026 https://padlet.com/10025026/lspbk894qb7j/wish/130970821 If you do not take good care of your heart then it may pump less efficiently and you may have heart failure.
