Treatment of isolated tricuspid regurgitation in 2020: an update.

Tricuspid valve regurgitation is an insidious pathology that is associated with increased mortality if left untreated. Conversely, surgical correction of tricuspid regurgitation is burdened by poor outcomes, especially when right ventricular dysfunction, kidney disease, or liver disease occur. There is, therefore, increasing interest in transcatheter approaches as an alternative to surgery in patients at high or prohibitive surgical risk. The development of percutaneous devices to treat tricuspid regurgitation has several technical challenges, mainly because of the complexity of valve anatomy, thus requiring accurate patient selection. Here we review the currently available transcatheter approaches to treat severe tricuspid regurgitation.
