Percutaneous Treatment of Tricuspid Regurgitation?

Tricuspid regurgitation (TR), a common form of valvular heart disease, frequently results from right ventricular dilatation and leaflet tethering, leading to malcoaptation of the leaflets. TR has been associated with poor long-term survival and with impaired response to correction of left-sided cardiac pathology. Nonetheless, surgical correction of TR is rarely performed, and the tricuspid valve is often described as the “forgotten valve.” To address this therapeutic challenge, device manufacturers are developing percutaneous approaches to tricuspid valve repair. This industry-sponsored, single-arm study (NCT03227757) examined echocardiographic and clinical outcomes of tricuspid valve edge-to-edge repair using the TriClip device, a non–FDA-…
