Background: Prevalence, predictors, and prognostic value of right ventricular (RV) function measured by the tricuspid annular plane systolic excursion (TAPSE) in patients with chronic heart failure (CHF) symptoms with a broad range of left ventricular ejection fraction (LVEF) are unknown. Methods and Results: Of 1,547 patients, mean (+/- SD) age was 71 +/- 11 years, 48% were women, median (interquartile range [IQR]) TAPSE was 18.5 (14.0-22.7) mm, mean LVEF was 47 +/- 16%, 47% had LVEF 545% and 67% were diagnosed with CHF, defined as systolic (S-HF) if LVEF was <= 45% and as heart failure with preserved ejection fraction (HFPEF) if LVEF was >45% and treated with a loop diuretic. During a median (IQR) follow-up of 63 (41-75) months, mortality was 34%. In multivariable analysis, increasing age, N-terminal pro B-type natriuretic peptide (NT-proBNP), New York Heart Association functional class, right atrial volume index, and transtricuspid pressure gradient; lower TAPSE, diastolic blood pressure, and hemoglobin; and atrial fibrillation (AF) or COPD were associated with an adverse prognosis. Receiver operating characteristic curve analysis identified a TAPSE of 15.9 mm as the best prognostic threshold (P = .0001); 47% of S-HF and 20% of HFPEF had a TAPSE of <15.9 mm. The main associations with a TAPSE <15.9 mm were higher NT-proBNP, presence of atrial fibrillation and presence of LV systolic dysfunction. Conclusions: In patients with CHF, low values for TAPSE are common, especially in those with reduced LVEF. TAPSE, unlike LVEF, was an independent predictor of outcome.
