Right ventricle-pulmonary artery coupling (RVPAC) has emerged from pathophysiology to clinical interest for prognostic implication in heart failure and is commonly measured as the ratio between tricuspid annular plane systolic excursion and systolic pulmonary artery pressure (TAPSE/SPAP). However, feasibility of SPAP is limited (down to 60% in trials, and maybe lower in clinical practice). We ought to assess the prognostic value of the TAPSE times pulmonary acceleration time (TAPSE x pACT) product and TAPSE to peak tricuspid regurgitation velocity (TAPSE/TRV) ratio as new alternative measures of RVPAC.

Abstract
Right ventricle-pulmonary artery coupling (RVPAC) has emerged from pathophysiology to clinical interest for prognostic implication in heart failure and is commonly measured as the ratio between tricuspid annular plane systolic excursion and systolic pulmonary artery pressure (TAPSE/SPAP). However, feasibility of SPAP is limited (down to 60% in trials, and maybe lower in clinical practice). We ought to assess the prognostic value of the TAPSE times pulmonary acceleration time (TAPSE x pACT) product and TAPSE to peak tricuspid regurgitation velocity (TAPSE/TRV) ratio as new alternative measures of RVPAC.File in questo prodotto:
