This article covers mitral valve grossing.
The aortic valve is dealt with in a separate protocol.
Introduction
- In the Western world, the most common pathology is mitral valve prolapse.[citation needed]
- Historically, rheumatic heart disease was very common. This is still significant in developing countries.[1] This classically has a fish-mouth appearance (valve orfice is slit-like, due to valve thickening) and is associated with cordae tendinae abnormalities.
- It may under go myxomatous degeneration, as can be seen in Marfan syndrome.
Protocol
- Specimen: mitral valve tissue.
- Number of leaflets: [ number ].
- Measurements:
- Valve (base-to-free edge x along the free edge x thickness): H x L x T, H x L x T and H x L x T cm.
- Cordae tendinae (length x thickness): L x T cm.
- Calcification: [ absent / suspicious / present ], [ minimal / moderate / marked ].
- Vegetations: [ none / suspicious / present ].
- Thinning: [ absent / present ].
- Hooding: [ absent / present / marked ].
- Cordae tendinae: [ normal / thickened / shorted / fused ].
- Additional findings: [ none / fish mouth appearance ].
- Representative sections are submitted from each cusp in block A1.
Protocol notes
- May be a gross only diagnosis.
- Sections are cut perpendicular to the free edge should include cordae tendinae.
