Three-Dimensional Echocardiography for Tricuspid Valve Assessment

Purpose of Review This review article provides an overview of the various roles of 3-dimensional (3D) echocardiography in the evaluation of the tricuspid valve (TV) with specific focus on tricuspid regurgitation (TR) and its treatment. Recent Findings The prognostic implications of TR and the advent of new transcatheter therapies have underscored the need of accurate assessment of the TV. 3D echocardiography is key to assess the anatomy and function of TV and has provided new insights that have led to new classifications of the type of TR. Furthermore, 3D echocardiography is superior to 2-dimensional echocardiography to assess the right ventricle, an important parameter to select the patients with severe TR who may benefit from intervention. Finally, the use of 3D echocardiography during the guidance of transcatheter interventions is pivotal to ensure procedural success and minimize the complications. Three-dimensional echocardiography provides the soft tissue resolution that fluoroscopy does not provide.
