There are three types of bicuspid aortic valves — types 0, 1, and 2. Experts classify these types based on whether the leaflets of the valve have fused to form a ridge. A bicuspid aortic valve is 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 ...

• The first step in selecting a valve is determining its function. • Review Cv or pressure drop when considering one valve versus another. • Don’t overlook maintenance requirements when specifying a ...

is a fluid control device. It uses a 1/4 turn rotation to control the flow of media in various processes. Knowing the materials and functions of the parts is vital. It helps to choose the right valve ...
