Geometric changes after tricuspid annuloplasty and predictors of residual tricuspid regurgitation: a real-time three-dimensional echocardiography study

Abstract

Tenting angles of all three leaflets increase, whereas annulus diameters decrease, after TAP. Pre-TAP tenting volume and antero-posterior annulus diameter measured using RT3DE are independent predictors of residual TR severity, and measurement of these parameters may help to identify patients at high risk for severe residual TR, for whom TV replacement should possibly be initially considered.
