Geometric comparison of the mitral and tricuspid valve annulus: Insights from three dimensional transesophageal echocardiography
AIM To apply real time three-dimensional transesophageal echocardiography (RT3D TEE) for quantitative and qualitative assessment of the mitral valve annulus (MVA) and tricuspid valve annulus (TVA) in the same patient. METHODS Our retrospective cohort study examined the MVA and TVA in 49 patients by RT3D TEE. MVA and TVA shape were examined by TEE. The MVA and TVA volume data set images were a...
متن کاملThree-dimensional geometry of the tricuspid annulus in healthy subjects and in patients with functional tricuspid regurgitation: a real-time, 3-dimensional echocardiographic study.
BACKGROUND Most rings currently used for tricuspid valve annuloplasty are formed in a single plane, whereas the actual tricuspid annulus (TA) may have a nonplanar or 3-dimensional (3D) structure. The purpose of this study was therefore to investigate the 3D geometry of the TA in healthy subjects and in patients with functional tricuspid regurgitation (TR). METHODS AND RESULTS This study consi...
متن کاملTricuspid annulus: A spatial and temporal analysis
BACKGROUND Traditional two-dimensional (2D) echocardiographic evaluation of tricuspid annulus (TA) dilation is based on single-frame measurements of the septolateral (S-L) dimension. This may not represent either the axis or the extent of dynamism through the entire cardiac cycle. In this study, we used real-time 3D transesophageal echocardiography (TEE) to analyze geometric changes in multiple...
متن کاملAnatomy of the Tricuspid Annulus
Background. Little anatomic information is available on the annular myocardium. This study was conducted to determine the anatomic substrate for atrial flutter due to circus movement around the tricuspid annulus in the Y-shaped incision canine model of atrial flutter. Methods and Results. We studied photographs of the annular myocardium serial histological sections, made in either of three diff...
متن کاملComparison of 2-Dimensional, 3-Dimensional, and Surgical Measurements of the Tricuspid Annulus Size: Clinical Implications.
BACKGROUND Associated tricuspid annuloplasty is recommended during left-heart valve surgery when the tricuspid annulus (TA) is dilated but methodology for the measurement of TA size and thresholds for TA enlargement are not clearly defined. METHODS AND RESULTS Measurement of the TA diameter (TAD) was prospectively performed using 2-dimensional transthoracic echocardiography (2D-TTE) in 282 pa...
