Golden Troy and his wife. Pneumatic pump sound reminds them that everything goes well.Cardiac diseases threaten the lives of millions of people and with a limited number of hearts available for transplantation, medical science was dreaming since long time a definitive solution to repair or replace this vital organ.Golden Troy, pastor of Oklahoma, United States, was born with a heart condemned at slaughter.
Since its birth, a genetic disorder known as Marfan syndrome was slowly attack their tissues, including those who have heart and their valves.
41 Years old, he had to undergo surgery have replaced their valves and the walls of his heart was reformed. However, although the intervention saved the lives his illness continued worsening.
In January 2010, put on the waiting list to receive heart transplant, but it was a battle against the clock without a donor.
"The heart of Troy was so bad that a traditional heart pump would not be enough." "" Why we decided to try something different: replace his heart completely ", explained his cardiologist, Dr. Doug Horstmanshof."
And in September of last year, Golden became one of the few individuals in the .uu United States. whose heart was completely replaced by a device called a Total artificial heart.
It is a core of plastic, weighs 160 grams and slightly larger than a biological heart. Driven by a pneumatic pump, the patient takes in a backpack.
The surgeon in charge of the operation, James Long, recalls the time when he submitted to heart gold. "It was obviously very impressive" said, "" and sinister a look inside the chest, and knew that the only thing that kept alive was synthetic pump comes to replace your heart."
The pump which leads to the heart of plastic is carried in a backpack.Golden had to get used to the constant noise of pneumatic pump. But it looks good, says he feels much better and you excited at what they have done for him.
"It's impressive hospital and return home and return to living a relatively normal life", explains.
"It is difficult to imagine what that meant they get you to heart because it is believed that without heart, it is not living", he adds.
Total artificial heart has not only extended the life of Golden, but he gave hope. But it is not a permanent solution.
Batteries of your heart must constantly reload, spare parts need to be ready. The risk of infection and coagulation increasing constant concern.
At the moment, or a supporter the long wait for a donor, but there are alternatives in sight. New methods of research are focusing on using the heart, rather than to replace it.

Use Miniature bomb in cardiac arrest patients is increasingly common. What about the size of a cigarette and essentially linked to the main Chamber of the heart pumping function can help.
Unlike artificial heart of Golden, miniaturized pumps can be indefinitely inside. But perhaps most remarkable is the fact that sometimes, they can take, once the diseased heart has recovered.
Incidentally, some of the most exciting research time is focused on potential really heal damaged hearts.
There is much interest in stem cells, which can become natural alternative for those parts of the body and under appropriate conditions, can be transformed into a large number of different types of cells, with specialized functions. For this reason, they can participate in the process of renewal, replacement of damaged and diseased tissues.
Preliminary results are very controversial, but it is proved that in the future might use regenerative capacity of the heart of therapies.
In a more radical investigation, DRA. Doris Taylor from the University of Minnesota, USAUU., uses stem cells makes hearts in the laboratory.
Millions of people suffer from heart failure.Until now, has been successful with the heart of a rat who has abducted their cells. This perfect scaffold heart shaped has reforested stem cells into cardiac tissue than subsequently, the heart beat again.
"The idea would be to take a heart, probably a pig, remove all cells and then take the patient's cells and grow enough to make an once implanted heart body rejects not, explains Taylor."
If your clinical application of the function, it would be a revolutionary but relatively remote possibility.
Golden and millions of people for whom heart failure is a reality, this work is essential.
There is a very real possibility that in the next few decades, scientists can finally find the cure you are looking for.
The research for this magical remedy will not be the end of the night, each discovery triggers a little more.
