Abstract
The tricuspid valve (TV) is a complex anatomical entity. As surgical treatment for isolated tricuspid regurgitation has traditionally been associated with high peri- and post-operative mortality, advances in percutaneous transcatheter techniques of repair and replacement of the TV are emerging as safe and effective alternatives. This review summarizes the current evidence on the use of three-dimensional echocardiography to assist transcatheter-edge-to-edge repair (TEER) in patients with tricuspid regurgitation.
