An experimental "mini heart" could help people with a medical condition that causes blood to pool in their veins by pumping their blood through the vessels and back to the heart, researchers say.

The mini hearts are tiny pumps, consisting of a cuff of heart muscle cells. Once implanted to surround a vein, they could contract rhythmically, squeezing blood through the vessel. A patient's own stem cells could be used to make the mini heart, decreasing the chances of tissue rejection, researchers say.

"We can create a simple version of the heart, outside a person's own heart," and by placing it in the lower extremities, significantly improve blood flow through a person's veins, said Narine Sarvazyan, a pharmacologist and physiologist at George Washington University in Washington, D.C., who led the research published in the February 4 issue of the Journal of Cardiovascular Pharmacology and Therapeutics.
