A beating biorobotic heart aims to better simulate valves

Combining a biological heart and a silicone robotic pump, researchers created a biorobotic heart that beats like a real one, focusing on a valve on the left side of the heart. The heart valve simulator, presented on January ...

Transcatheter mitral valve repair safe and effective, study finds

Long-awaited outcomes data of transcatheter edge-to-edge procedures to repair patients' leaky mitral valves revealed the minimally invasive procedure to be safe and effective in nearly 90% of patients, according to Cedars-Sinai ...

Neuroscience

Researchers show serotonin can contribute to heart valve disease

The neurotransmitter serotonin can adversely affect the heart's mitral valve, contributing to a heart disease known as degenerative mitral regurgitation, according to a new multicenter study involving researchers from the ...

Cardiology

Heart valves strive to get oxygen one way or another

As the valves in a heart stretch with each beat, their cells take in life-giving oxygen. But if the supply is cut off, aortic and mitral valves use different strategies to compensate, according to Rice University scientists.

Genetics

Team identifies first gene that causes mitral valve prolapse

An international research collaboration led by Massachusetts General Hospital (MGH) investigators has identified the first gene in which mutations cause the common form of mitral valve prolapse (MVP), a heart valve disorder ...

Cardiologists publish case series study on heart valve procedure

Findings from a published case series research letter by the Henry Ford Health Structural Heart Disease team show that severe mitral stenosis, due to a build-up of calcium deposits in the mitral valve common in elderly patients, ...
