Heart repair without surgery

Heart repair breakthroughs replace surgeon's knife - Yahoo! News

Heart care is in the midst of a transformation. Many problems that once required sawing through the breastbone and opening up the chest for open heart surgery now can be treated with a nip, twist or patch through a tube.

[...]

All rely on catheters — hollow tubes that let doctors burn away and reshape heart tissue or correct defects through small holes in blood vessels.

"This is the replacement for the surgeon's knife. Instead of opening the chest, we're able to put catheters in through the leg, sometimes through the arm," said Dr. Spencer King of St. Joseph's Heart and Vascular Institute in Atlanta. He is former president of the American College of Cardiology. Its conference earlier this month featured research on these novel devices.

Artificial Heart Ready for Implantation

clipped from news.bbc.co.uk 'Full' artificial heart implant Scientists say they have a working prototype of a fully artificial heart ready for implanting in humans. The device beats almost exactly like the real thing using electronic sensors to regulate heart rate and blood flow. Developers Carmat now need approval from the French authorities before pushing ahead with clinical trials. But heart experts warned it was still early days as previous attempts to create a fully artificial heart had failed during human testing. I couldn't stand seeing young, active people dying aged 40 from massive heart attacks Professor Alain Carpentier Only properly conducted clinical trials will establish whether this version will live up to the claims made by its manufacturers Peter Weissberg of the British Heart Foundation The device is designed to be as similar as possible to the human heart

Beating Heart Created In the Lab

clipped from www.medgadget.com Researchers Create Beating Heart In Lab Professor Doris Taylor and his team at the University of Minneapolis have done the impossible. They have successfully "built" a beating heart in the lab, an organ potentially suitable for autologous transplants, at least for rats and pigs in whom the research was conducted. Video: Researchers create a new heart in the lab clipped from www.nature.com Rat organs can be stripped of their cells and regrown to pump blood. Rat hearts, stripped of their cells by detergents, have been used as a scaffold to engineer a bioartificial heart, which can amazingly pump a little like the original organ. With further development, the method may one day be used to repair heart damage or even generate new hearts for transplantation. Cell-free hearts from pigs, for example, could serve as scaffolding to grow a heart with human cells, researchers say, because pig hearts are of a similar size and complexity to human hearts.
