Transcatheter procedures for tricuspid regurgitation in advanced heart failure: A systematic review

Tricuspid regurgitation (TR) in advanced heart failure (HF) is associated with poor prognosis, functional decline, and increased morbidity. This systematic review synthesizes current evidence of transcatheter device tricuspid transcatheter approaches in advanced HF patients. A comprehensive search of PubMed, Embase, Scopus, CINAHL, and the Cochrane Library identified studies evaluating transcatheter procedures for moderate-to-severe TR in advanced HF, and reporting procedural outcomes, survival, and functional measures. A total of 37 studies encompassing approximately 2,372 patients were included, spanning edge-to-edge repair systems (TriClip, PASCAL), annuloplasty devices (Cardioband, Trialign, TriCinch), transcatheter valve replacement (Evoque, LuX-Valve, NaviGate, Intrepid), heterotopic caval valve implantation (TricValve, Tricento), and leaflet spacers (FORMA). Most patients were in NYHA class III-IV with high surgical risk scores. Across techniques, procedural success rates were high, with consistent reductions in TR severity and improvements in NYHA class, 6-minute walk distance, and quality-of-life scores. Edge-to-edge repair was the most frequently studied, showing favorable safety and symptom improvement. Mortality rates varied, with limited long-term follow-up data. Transcatheter interventions for TR in advanced HF offer promising improvements in symptoms, functional status, and quality of life. Given patient and anatomical heterogeneity, an individualized approach is essential.
