The mitral valve is an essential part of your heart. Matter of fact, you wouldnt exist without it. The valve is essentially a small, round hole with two flaps on the top and bottom. Its job is to open and close rapidly, regulating the flow of blood between the upper and lower chambers of the hearts left side- the main pumping chambers that send oxygen-rich red blood to your limbs and organs.
In some people, however, the mitral valve can leak, usually because of a congenital deformity or after a serious heart attack when the heart muscle itself is damaged. "Significant leakage of the mitral valve can shorten someones life, not to mention making it tough to go about the activities of daily living," said Dr Scott Lim, a cardiologist at the University of Virginia Health System.
For years, the standard of care for mitral valve leakage has been open-heart surgery with the patient on a bypass machine. Now, heart patients at the UVa Health System have a new, less invasive, option to get a leaky valve fixed.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
