notes: label: Description (Brief)
content: This is a Cross-Jones non-tilting disc mitral valve developed by Dr. Frederick Cross, MD. It is a size 90 with a lens weight of 2.6463 grams and serial number H-0021-9. Non-tilting valves fell into disuse because of issues such as frequent thromboembolic complications, and the destruction of blood cells known as hemolysis. The Cross-Jones valve was manufactured between 1967 and 1974. It has an open cage composed of three metal struts. The disc is radiolucent silicone rubber with a titanium ring to strengthen the disc and make it radiopaque. Other complications included cocking of the disc, retrograde dislodgement, and disc variance.
