Clinical Impact of Size, Shape, and Orientation of the Tricuspid Annulus in Tricuspid Regurgitation as Assessed by Three-Dimensional Echocardiography

Tricuspid annuloplasty for tricuspid regurgitation (TR) depends on the measurements of tricuspid annular diameter (TAD) obtained in an apical four-chamber view on two-dimensional (2D) transthoracic echocardiography (TTE). We performed a combined 2D and three-dimensional (3D) echocardiographic study to understand the impact of the size, shape, and orientation of a dilated annulus on the inconsistencies between measured 2D TTE-TAD and the actual annular diameter.
