Performance of Guideline-Recommended Approaches to Echocardiographic Investigation for Pulmonary Hypertension: Analysis of the CIPHER Study.

ABSTRACT: Guidelines recommend different approaches to investigate for pulmonary hypertension (PH) by transthoracic echocardiography (TTE). We used data from the CIPHER study (NCT04193046) to prospectively evaluate TTE detection of PH. Participants newly referred to PH clinics who underwent right heart catheterization (RHC) within 6 weeks and TTE within 60 days of enrolment (blinded central TTE reading) were classified by TTE probability of PH applying (i) the 2015 European Society of Cardiology (ESC)/European Respiratory Society (ERS) TTE algorithm or (ii) right ventricular systolic pressure (RVSP) > 40 mmHg. For calculation of sensitivity and specificity, 'non-assessable' patients (peak tricuspid regurgitation velocity [TRV] missing or ≤ 2.8 m/s with missing data on other echocardiographic signs)
