A Novel Device for Tricuspid Regurgitation Reduction Featuring 3-Dimensional Leaflet and Atraumatic Anchor: Pivot-TR System

A new device called the Pivot-TR system was designed to treat tricuspid regurgitation with a novel spacer crossing the valve vertically. Its unique atraumatic anchoring system composed of both the elephant long nose and the inferior vena cava spiral anchor, in addition to the relatively easy implantation mechanism, enabled easy retrieval of the system later on. The system showed promising feasibility and safety results in this swine-based animal experiment, which should encourage human translation study.
