Stages

Stage	Definition	Anatomy of the valve	Hemodynamics of the valve	Hemodynamic changes	Symptoms
A	At risk	Primary TR Mild rheumatic change Mild prolapse Findings related to other conditions (IE, carcinoid, radiation) Presnece of an intra-annular RV pacemaker or ICD lead Cardiac transplant (biopsy related) Secondary TR No abnomrla findings Beginning of annular dilation || Absent || Absent || Absent
B	Progressive	Primary Progressive leaflet deterioration/destruction Moderate-to-severe prolapse and limited chordal rupture Secondary Beginning of annular dilation Moderate leaflet tethering || Mild TR Central jet area <5.0 cm2 Undefined width of vena contracta Soft and parabolic CW jet density and contour Systolic dominance of hepatic vein flow Moderate TR Central jet area 5–10 cm2 Undefined width of vena contracta width but <0.70 cm Dense, variable CW jet density and contour Systolic blunting of hepatic vein flow || Mild TR Normal size of RV/RA/IVC Moderate TR Absence of RV enlargement Absent or mild RA enlargement Absent or mild IVC enlargement with normal respirophasic variation Normal RA pressure || None
