Tricuspid regurgitation (TR) is common in patients with heart failure with preserved ejection fraction (HFpEF), but it has not been well characterized. We hypothesized that right atrial (RA) remodeling would be associated with TR in HFpEF, forming a type of atrial functional TR (AFTR). Echocardiography was performed in 328 patients with HFpEF.

Interstitial lung disease (ILD) is common in CTD patients and subtle interstitial abnormalities detected by lung ultrasound could predict exercise-induced pulmonary hypertension (PH).
Methods And Results: Echocardiography and lung ultrasound were performed at rest and bicycle exercise in CTD patients (n = 41) and control subjects without CTD (n = 24).
Background: Few studies have investigated right atrial (RA) remodeling in heart failure (HF) with preserved ejection fraction (HFpEF). This study sought to characterize the RA remodeling in HFpEF and to determine its prognostic significance.
Methods And Results: Patients with HFpEF were classified based on the presence of RA enlargement (RA volume index >39 mL/m in men and >33 mL/m in women).
Aims: This study sought to determine the independent and incremental prognostic value of semiquantitative measures of tricuspid regurgitation (TR) severity over right heart remodelling and pulmonary hypertension (PH) in heart failure with preserved ejection fraction (HFpEF).
Methods And Results: Echocardiography was performed on 311 HFpEF patients. TR severity was defined by the semiquantitative measures [i.
