Right ventricular recovery during follow-up is associated with improved survival in patients with chronic heart failure with reduced ejection fraction

AIMS A compromised tricuspid annular plane systolic excursion (TAPSE) is associated with worse survival in patients with chronic heart failure with reduced ejection fraction (HFrEF). However, it is not known whether a reversible abnormal TAPSE at follow-up predicts survival. Our aim was to evaluate whether a reversible abnormal TAPSE is associated with a better survival in patients with chronic HFrEF. METHODS AND RESULTS A complete echocardiography was performed in 706 patients with chronic HFrEF (LVEF ≤45%) at baseline and after 6 ± 3 months. Right ventricular (RV) systolic function was evaluated using TAPSE. The study endpoint was all-cause mortality. At baseline, TAPSE was severely reduced (≤14 mm) in 89 (13%) patients, and slightly reduced (>14 but
