Gut Microbial Metabolites and Intestinal Permeability in Patients With Severe Tricuspid Regurgitation Undergoing Transcatheter Tricuspid Valve Intervention (INTEGRITY)
MicrobIal Metabolites and Gut Leakiness assessmeNT in Patients With sevEre Tricuspid reGuRgItation Undergoing Transcatheter Tricuspid Valve inTervention: a Multidimensional analYsis (INTEGRITY-Trial)
Emerging evidence highlights a bidirectional gut-heart axis, particularly relevant in patients with right heart failure. Elevated right atrial pressures and systemic congestion may impair intestinal perfusion and compromise epithelial integrity, leading to increased gut permeability ("leaky gut") and translocation of microbial products. These processes can trigger systemic inflammation and exacerbate cardiac dysfunction. Alterations in the gut microbiome-collectively referred to as dysbiosis-have also been linked to heart failure pathogenesis. However, the role of intestinal barrier dysfunction and microbial signatures in patients with severe tricuspid regurgitation (TR) remains largely unexplored.

Aktywny komparator: TTVI Cohort
Patients with severe functional tricuspid regurgitation undergoing transcatheter tricuspid valve intervention (TTVI) as part of routine clinical care. The decision to perform TTVI is made independently of study participation. Patients undergo longitudinal assessment of gut microbial metabolites, intestinal permeability, and clinical parameters. |
