Abstract

Tricuspid regurgitation (TR) is frequently detected, especially in its secondary form, while primary TR is far less frequent. Similar to mitral regurgitation (MR), primary tricuspid regurgitation should require timely intervention to avoid secondary damage of the RV, which is associated with poor outcome. Current guidelines suggest that secondary TR should be treated at the time of left-sided valve surgery, although a surgical option is rarely offered to high-risk patients with combined heart valve disease. As such, while the transcatheter approach to mitral valve repair/replacement has become a major goal of the transcatheter therapies, the transcatheter tricuspid valve intervention is still at a very early stage.
