Jennifer Mathews: Two people -- Gloria Shelby: They said my heart was so weak, until it -- just wouldn't continually pump in by itself. Jennifer Mathews: Two hearts that stopped working. Ed Layton: I was dying. It actually -- the heart attack blew a hole in my heart. Jennifer Mathews: Chronic heart failure kills thousands each year. A heart transplant is an option, but many die waiting for one. Now, cutting edge research offers something better. Dr. Ravi Birla: If we think about science fiction, the ability to have a total bioartificial heart implanted back into the patient may be a lifesaving option for some cases where there simply is no other option available. Jennifer Mathews: Researchers at the University of Michigan are growing heart muscle and valves in the lab. A biological replacement could be an almost exact match of the real thing. Scientists first take cardiac cells from rats. That's combined with a fibrin gel to make 3D tissue. Electromechanical stimulation from a bioreactor gives the cells the same environment they're used to in the body. The goal is to put the created tissue back into the body as replacement heart muscle or make new valves, vessels, and ventricles. Dr. Ravi Birla: The whole concept of being able to grow tissue-engineered products and the components of the heart. It sort of gives you a reason to wake up in the morning and come to work. Jennifer Mathews: They are still years away from actually using lab-created heart parts in patients, but the scientists say, it could revolutionize modern medicine. This is Jennifer Mathews reporting.
