This article covers mitral valve grossing.

The aortic valve is dealt with in a separate protocol.

Introduction

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.
