Clinical research on echocardiographic screening for pulmonary hypertension: TRV >2.8 m/s and mPAP >20 mmHg.

ABSTRACT:

Background

In 2022, the European Society of Cardiology (ESC) and the European Respiratory Society (ERS) revised the diagnostic criteria for pulmonary hypertension (PH) from mean pulmonary arterial pressure (mPAP) ≥25 mmHg to >20 mmHg. However, the echocardiographic standards [the tricuspid regurgitation velocity (TRV) >2.8 m/s] have not been updated. This study aims to optimize the reference value of TRV, and evaluate the discriminatory efficacy of TRV in pulmonary artery pressure grading.

Methods

Patients suspected of having PH underwent both ultrasound (US) and right heart catheterization (RHC) examinations. The TRV and tricuspid regurgitant pressure gradient (ΔPTR) were measured via US. Right atrial pressure (RAP) was estimated via US by related parameters of the inferior
