The tricuspid valve is currently the subject of much interest from echocardiographers and surgeons. Functional tricuspid regurgitation is the most frequent aetiology of tricuspid valve pathology, is characterized by structurally normal leaflets, and is due to annular dilation and/or leaflet tethering. A primary cause of tricuspid regurgitation with/without stenosis can be identified only in a minority of cases. Echocardiography is the imaging modality of choice for assessing tricuspid valve diseases. It enables the cause to be identified, assesses the severity of valve dysfunction, monitors the right heart remodelling and haemodynamics, and helps decide the timing for surgery. The severity assessment requires the integration of multiple qualitative and quantitative parameters. The recent insights from three-dimensional echocardiography have greatly increased our understanding about the tricuspid valve and its peculiarities with respect to the mitral valve, showing promise to solve many of the current problems of conventional two-dimensional imaging. This chapter provides an overview of the current state-of-the-art assessment of tricuspid valve pathology by echocardiography, including the specific indications, strengths, and limitations of each method for diagnosis and therapeutic planning.

Abstract Aims  We sought to investigate tricuspid valve (TV) geometry and right heart remodelling in atrial functional tricuspid regurgitation (AF-TR) as compared with ventricular functional TR with sinus rhythm (VF-TR). Methods and results  Transoesophageal 3D echocardiography datasets of the TV and right ventricle were acquired in 51 symptomatic patients with severe TR (AF-TR, n = 23; VF-TR, n = 28). Three-dimensional right ventricular (RV) endocardial surfaces were reconstructed throughout the cardiac cycle and then postprocessed using semiautomated integration and segmentation software to calculate position of papillary muscle (PM) tips. Compared with VF-TR, AF-TR had more dilated and posteriorly displaced annulus and less leaflet tethering angles with more prominent right atrium and smaller RV end-systolic volume. On the XY (annular) plane, the centre of annulus was getting closer towards the anterior and posterior PM tips and was going away from the medial PM tip caused by prominent annular dilatation in AF-TR. On the Z-axis, the position of each PM tip in AF-TR was not so much displaced apically as that in VF-TR. Multiple linear regression analyses revealed that right atrial volume and right atrial/RV end-systolic volume ratio were determinants of annular area and orientation in AF-TR, respectively (both P < 0.001). Additionally, the posteromedial-directed component of posterior PM tip position and the apically directed component of the position of all three PM tips were independently associated with TV tethering angles of each leaflet in AF-TR (all P < 0.02). Conclusion  Right heart remodelling and its association with 3D TV geometry differ entirely between AF-TR and VF-TR, which may offer distinctive therapeutic implication.

Historically, the research on the right ventricle (RV) has been neglected by his left equivalent because of the complexity of left ventricle (LV) dysfunction. Tricuspid regurgitation (TR) can be classified as linked to primary valve disease or functional in nature, but most are functional. Although it was historically assumed that such functional Tricuspid regurgitation, i.e. arising from leftsided disease, and it can be resolved after corrective surgery, but after successful surgery, on the aortic or mitral valve annular dilatation, the Tricuspid regurgitation and right ventricular dysfunction may persist.To study the circumference of tricuspid orifice and it’s the diameter in two perpendicular planes and its comparison among the male and female population. The material for the present study comprised of 50 formalin fixed human hearts (35 males and 15 females) which were obtained from the department of anatomy. In this study, it is observed that: The mean value of circumference of a tricuspid orifice is 11.01+/-0.63 cm. The diameter of tricuspid orifice along the frontal dimension is 3.06+/-0.38 cm, and the diameter along the sagittal dimension is 2.26+/-0.23 cm. The measurements of the circumference of tricuspid orifice reported for males and females in western countries were higher than the present study and the diameter along the frontal dimension is greater than the diameter along the sagittal dimension. The tricuspid valve diameter along the frontal dimension was more than the diameter along the sagittal dimension in both males and females.
