Tricuspid valve regurgitation is generally functional in nature due to right-sided dysfunction in the setting of left-sided concomitant cardiac disease or pulmonary hypertension. Patients living with tricuspid regurgitation often experience numerous limitations as a result of right-sided heart failure symptoms. Patients with significant tricuspid disease, whether native, repaired, or replaced valve, often present with significant symptoms but may not be ideal candidates for operation or, eventually, reoperation. Transcatheter techniques to either repair or replace the tricuspid valve are a burgeoning frontier in structural cardiac interventions. Anatomical challenges include the large and asymmetrical annulus, paucity of calcification, adjacency of the right coronary artery system, and fragility of the valve tissue. Current approaches under investigation in feasibility and early phase clinical trials include edge-to-edge repair, coaptation enhancement, annuloplasty, heterotopic caval valve implantation, and percutaneous tricuspid valve replacement. Although there are limitations to the currently available transcatheter options for the patients, the initial data demonstrate the relative safety of using existing devices with good results and functional improvement. Hopefully, the emerging interest into interventional therapy of tricuspid valve disease will bring back the "forgotten valve" into the conscience of the cardiological and surgical community. This review intends to summarize the current strategies and evidences in transcatheter tricuspid valve intervention and enlightening new avenues for future clinical studies.
