Right ventricular to pulmonary artery (RV-PA) coupling has been established as a prognostic marker in patients with severe tricuspid regurgitation (TR) undergoing transcatheter valve interventions (TTVI). RV-PA assesses right systolic function related pressure levels, which are ideally measured by heart catheterization. This study aimed improve the concept relating annular plane excursion (TAPSE) mean (mPAP) levels. Moreover, instead of catheterization, this sought employ an extreme gradient boosting (XGB) algorithm predict mPAP levels based on standard echocardiographic parameters. multicentre included 737 TTVI for TR; among them, 55 from one institution served external validation. Complete echocardiography and catheterization data were available all patients. The XGB trained 10 parameters could reliably evaluated validation (Pearson correlation coefficient R: 0.68; P value: 1.3 × 10-8). predicted (mPAPpredicted) superior (sPAPechocardiography) predicting 2-year mortality after [area under curve (AUC): 0.607 vs. 0.520; 1.9 10-6]. Furthermore, TAPSE/mPAPpredicted was TAPSE/sPAPechocardiography (AUC: 0.633 0.586; 0.008). Finally, preserved (defined > 0.617 mm/mmHg) showed significantly higher survival rates than reduced (81.5% 58.8%, < 0.001). independent association between confirmed multivariate regression analysis (P 6.3 10-4). Artificial intelligence-enabled assessment can refine risk stratification prior without necessitating invasive A comparison conservatively treated is mandatory quantify benefit accordance coupling.
