Why the study?
Invasive surgery for isolated functional tricuspid regurgitation is rarely performed due to high inpatient mortality, making transcatheter tricuspid valve intervention an appealing yet technically challenging alternative.
Transcatheter tricuspid valve intervention is an appealing but anatomically challenging alternative to high-risk invasive surgery for functional tricuspid regurgitation.
Demonstrates technical feasibility of transcatheter TR intervention; leaves open durability, safety, and efficacy in larger trials.
Functional tricuspid regurgitation (TR) develops secondary to annular dilation and leaflet tethering as a result of right ventricular remodeling. Invasive surgery for isolated TR is rarely performed due to high inpatient mortality. Transcatheter tricuspid valve intervention is an appealing solution but is challenging as crucial structures are closely related to the tricuspid valve, and intracardiac devices pose further challenges to device delivery and implantation.
