Overview
TAD by 2D-TTE varies by view in left-heart valve patients; leaves open standardized thresholds for tricuspid annuloplasty decisions.
Structured PICO
Does 2D-TTE accurately measure tricuspid annulus size compared to 3D-TEE and surgical measurements?
P
Population
282 patients undergoing echocardiography, a subset of 183 undergoing 3D-TEE, 120 undergoing tricuspid valve surgery, and 66 healthy volunteers.
I
Intervention
Measurement of tricuspid annulus diameter (TAD) using 2-dimensional transthoracic echocardiography (2D-TTE) across 4 different views.
C
Comparator
Measurement of TAD using 3-dimensional transesophageal echocardiography (3D-TEE) and direct surgical measurement.
O
Outcome
Tricuspid annulus diameter (TAD) measurement differences, feasibility, reproducibility, and correlation between modalities.surrogate
2D-TTE in the apical 4-chamber view is highly feasible and reproducible for measuring tricuspid annulus size, accurately reflecting 3D-TEE measurements despite a systematic 4-mm underestimation.
