Fortuni et al reported an algorithm for grading secondary tricuspid regurgitation using echocardiography. The authors are Leiden Univresity, University of Pavia, Middleheim Hospital, University of Torino and University of Turku.
Patient selection: secondary tricuspid regurgitation
Parameters:
(1) vena contracta width in mm (point in a fluid stream where the diameter of the stream is the least and the fluid velocity is maximal)
(2) effective regurgitant orifice area (EROA) in square mm
Vena Contracta
EROA
Severity
< 7 mm
NA
moderate
>= 7 mm
< 80 square mm
severe
>= 80 square mm
torrential
