What type of valve is a St. Jude valve classified as?

The St. Jude valve is classified as a bi-leaflet mechanical valve. This type of valve is designed with two leaflets that open and close to regulate blood flow through the heart. The bi-leaflet design allows for a more physiological flow characteristics and minimizes flow turbulence compared to some other valve types. Mechanical valves, like the St. Jude, are made from synthetic materials and have the advantage of durability and longevity; they are typically recommended for younger patients who need a valve replacement and can manage anticoagulation therapy.

Understanding the specifics of the St. Jude valve’s bi-leaflet mechanism is important for echocardiographic evaluations, as it significantly influences the assessment of the valve's function and the underlying device integrity.
