Case 200: Mitral Valve and Annular Terminologies

This is a snippet that deals with the different terminologies and conditions that affect the mitral valve.

Stenosis - jet into LV across MV in diastole
Regurgitation - jet into LA across MV in systole
Thickening - > 5 mm thickness
Hockey-stick and fish-mouth appearances of rheumatic mitral valve disease
Prolapse - most atrial part of the coaptation line > 2 mm into the LA
Billowing - displacement > 2 mm of any leaflet tissue into LA in systole
Flail - the undersurface of the mitral leaflet flips up and is exposed to the left atrium
Mitral-Annular Disjunction (MAD) - > 2 mm separation between LV myocardium and mitral annulus
Annulus Expansion - abnormal expansion of annulus in systole rather than contraction
Curling - paradoxical systolic motion of the posterior mitral ring on the adjacent myocardium
