“…Its anterior and posterior portions are muscular, whereas the septal part is more fibrous, which explains predominant antero-posterior annular dilation as well as the spherical and planar shape of the annulus in patients with severe functional TR (11,24). The tricuspid annulus is contiguous to several important anatomical structures (25). The postero-septal portion is close to the ostium of the coronary sinus, delimiting the triangle of Koch, where both the atrio-ventricular (AV) node and His-bundle are located.…”

“…TR etiology can be divided in primary (or organic) TR due to leaflet abnormalities, and secondary (or functional) TR due to annular and right atrial, or right ventricular dilation (25). Diseases leading to leaflet deformation can be either acquired, such as rheumatic or carcinoid heart disease, endocarditis, trauma, or congenital, like Ebstein's anomaly and endocardial cushion defect (29).…”

With the emergence of transcatheter solutions for the treatment of tricuspid regurgitation (TR) increased attention has been directed to the once neglected tricuspid valve (TV) complex. Recent studies have highlighted new aspects of valve anatomy and TR etiology. The assessment of valve morphology along with quantification of regurgitation severity and RV function pose several challenges to cardiac imagers guiding transcatheter valve procedures. This review article aims to give an overview over the role of modern imaging modalities during assessment and treatment of the TV.

Three‐dimensional echocardiography for the assessment of the tricuspid valve

Tricuspid valve pathology is increasingly recognized as an important contributor to patient morbidity. Accordingly, interest in transcatheter interventions for tricuspid valve disease has continued to grow. Echocardiographic imaging of the tricuspid valve has therefore become an integral component of patient assessment and the essential imaging modality for interventional procedures. The need for improved tricuspid valve imaging has highlighted the variability in tricuspid valve anatomy and the difficulties of using two-dimensional (2D) echocardiography alone to determine the location and type of tricuspid valve disease. Here, three-dimensional (3D) imaging using tools such as biplane imaging, multiplanar reconstruction and live 3D acquisition allow a more accurate and efficient evaluation of the tricuspid valve. The 3D imaging of the tricuspid valve is often focused on transesophageal echocardiography, but the more anterior location of the tricuspid valve also lends itself to assessment with transthoracic echocardiography.In this review, we will examine how 3D imaging can complement and enhance the information obtained from 2D echocardiography, and present novel applications for the quantitation of valvular disease and its utility in intraprocedural imaging.

“…Tricuspid regurgitation (TR) affects > 1.6 million people in the United States and > 70 million people worldwide . Approximately 90% of TR in adults is functional (secondary) due to (i) left‐sided heart disease (valve disease or left ventricular dysfunction), (ii) pulmonary arterial hypertension (PAH), (iii) right ventricular (RV) dysfunction/chronic RV volume overload, or (iv) idiopathic [often associated with atrial fibrillation (AF)] . The majority of patients have trivial or mild TR, which may be non‐pathological.…”
