At baseline, the mechanical valve group tended to be younger (55.7 vs 65.2) and had less aortic stenois (82.4% vs 89.5%), but ...

1). Admedus is also rapidly developing a novel trans-catheter aortic valve replacement (TAVR) device. Current TAVR products on the market contain three separate pieces of tissue held together by ...

In many cases, the valve must be replaced. While narrowing of either the aortic or mitral valve typically requires valve replacement (with a manufactured “mechanical” valve, or with a tissue valve ...

New 20-year data show a survival rate of 90% with few repeat surgeries after this complex operation that can only be ...

A study reveals that middle-aged adults fare better with mechanical aortic valves compared to animal tissue-based valves. The research, presented at the Society for Thoracic Surgery annual meeting, ...

We redesigned the sewing ring to consist of multiple layers of cloth to achieve compressibility, thereby enhancing tissue contact ... also showed that mitral-valve replacement was possible with ...

Young patients who have undergone the Ross procedure for aortic valve disease have shown excellent long-term survival, the ...

The artificial valve might be mechanical (made of man-made substances). Others are made out of animal tissue, often from a pig. Aortic valve replacement gives you a new aortic heart valve. The new ...

These latest data reinforce years of smaller studies, but whether they should change practice is a matter of debate.

CABG plus surgical aortic valve replacement for treatment of coronary disease and aortic stenosis was associated with better 5-year outcomes vs. PCI plus transcatheter aortic valve replacement in ...

Existing valve replacement options for patients have major drawbacks. Valves taken from cows, pigs or human tissue and implanted in the patient only last a decade or so and can still be rejected ...
