New research may take the current 'gold standard' for heart valves to a new level of reliability. A team of researchers has developed a way to improve overall blood flow through the valves, so the ...

People with mechanical heart valves need blood thinners on a daily basis, because they have a higher risk of blood clots and stroke. Researchers now identified the root cause of blood turbulence ...

Calcification is the bane of the human heart valve. Human heart valves are plagued by stenosis 1 – or the thickening or stiffening of the valve leaflets caused by a build-up of calcium. Millions of ...

Mechanical heart valves are vital in restoring cardiac function in patients with valvular disease, and their performance is intimately linked to fluid dynamic phenomena. In these devices, complex flow ...

Every year, more than 5 million people in the U.S. are diagnosed with heart valve disease, but this condition has no effective long-term treatment. When a person's heart valve is severely damaged by a ...

Researchers have developed a method for cheaply producing heart valves in the span of minutes that are functional immediately after being implanted into sheep. The scientists call their method ...
