The quest for that perfect heart replacement seemed to be never-ending. Many professionals like surgeons, medical technicians and more, have work fore decades with hundreds of trial and error, but non hasn't come close to perfecting a working machine that does not wear out, breaks down, or work perfectly like a real heart while not causing clots and infections.

Recent developments in artificial heart research says that two surgeons could give someone with a failing heart more days and avoid the complication having artificial heart with just the simple whirling rotors.

Most artificial heart replaces the function of a failed heart by mimicking the organic movement by pumping blood rhythmically, contracting and then resting to producing a pulse or a heartbeat. Having a pulse one of the metrics that doctors measure to tell the difference between the living and what's not.

Dr. Billy Cohn and Dr. Bud Frazier at the Texas Heart Institute believes that they have developed the perfect heart replacement to date. They experiment on dozen of animals, particularly in calves. They've removed the heart of the animals and replaced with two centrifugal pumps. By doing so, the calves didn't have any pulse and heartbeat. The doctors said, the calves will be flat-lined in they will be hooked to an EKG and all metrics that is usually used to it was alive.

Being confident on the results of their 38 trials on animals, they started testing the artificial heart if they would have the same results to humans.

The 55 year old, Craig Lewis was the heart's first recipient. He was suffering from amyliodosis, a condition that causes a build up of abnormal protein. The build ups clogs organs until they stop working. In Lewis' case, doctors said he only had 12 hours to live having his heart damaged by his disease.

Lewis was implanted by an artificial heart made up of materials that can be usually found on most homes. Dr. Cohn said it was Dacron on the inside and fiberglass impregnated in silicon on the outside. The implanted artificial heart was developed from using two medical implants known as the ventricular assist device hook together.
