Class I for surgery
A
Severe, symptomatic EF >30% EF <60 LVESED >= 40 Repair > replacement if posterior or feasible Other cardiac surgery
2
Q
Type 1 movement MR
A
Normal
3
Q
Type 2 movement MR
A
Excessive
Mostly degenerative
4
Q
Type 3 movement MR
A
Restricted movement
A = diastole
B = systole
5
Q
Severe jet MR
A
Large central jet > 50% of LA
Eccentric wall-impinging jet
6
Q

A
Large, throughout systole
7
Q

A
Systolic flow reversal
8
Q

A
> = 0.40
9
Q
Severe RVol
A
> = 60
10
Q
Severe RF MR
A
> = 50%
11
Q
MV RVol eq
A
Rvol = MV SV - AV SV
12
Q
ERO using RVol MR
A
Rvol / R VTI
13
Q
Flow by PISA
A
2pi x aliasing velocity x r2
14
Q
ERO by PISA MR
A
ERO = flow / velocity
15
Q
Measure for holystolic MR
A
ERO > Rvol
