BACKGROUND: A mismatch between tricuspid leaflet size and annular dilation is one of the morphological features tied to the development of tricuspid regurgitation (TR). AIMS: We assessed the association of the leaflet-to-annulus index (LAI) with residual TR after transcatheter edge-to-edge repair (TEER). METHODS: Consecutive patients who underwent TEER for TR were enrolled. Significant residual TR was defined as a post-procedural TR ≥3+, and patients were divided into two groups according to the amount of residual TR. The LAI was retrospectively calculated using procedural transoesophageal echocardiography and was defined as follows: (anterior leaflet length+septal leaflet length)/septolateral tricuspid annulus diameter. RESULTS: Of 140 patients, 43 patients had residual TR ≥3+ after TEER. The patients with residual TR ≥3+ had a lower LAI compared to those with residual TR

Hepatorenal dysfunction is a strong risk factor in patients with heart failure (HF). We investigated the prognostic significance of hepatorenal dysfunction in 172 consecutive patients undergoing transcatheter tricuspid valve repair (TTVR). The model for end-stage liver disease excluding international normalized ratio (MELD-XI) score was calculated as 5.11 × ln(serum total bilirubin [mg/dl]) + 11.76 × ln(serum creatinine [mg/dl]) + 9.44. Patients were stratified into two groups: high (≥ 14) or low (
