TCT-430 Comparison of Tricuspid Annulus Measurements by 2D Transthoracic and Transesophageal Echocardiography, and 3D Automated Transesophageal Echocardiography With CT Annulus Measurements in Patients With Severe Tricuspid Regurgitation Being Evaluated for Transcatheter Intervention

Tricuspid annulus (TA) size is a key determinant of the suitability of annuloplasty-based transcatheter therapies of tricuspid regurgitation and an important predictor of procedural outcomes. It is also key for sizing transcatheter heart valve TV replacement techniques. Currently, contrast computed
