Algorithm for PAH screening in SSc. SPAP systolic pulmonary artery pressure estimated according to Bernoulli’s formula: VIT2 + POD estimated, PH pulmonary hypertension, SPAP systolic pulmonary artery pressure, PH pulmonary hypertension, VIT tricuspid regurgitation velocity, RAP right atrial pressure. *In absence of indirect signs of PH, no dilation of the right cavities, no shortening of the pulmonary acceleration time. Special attention must be given to patients with a cDLCO < 60%, especially for patients with a disease progression of more than 3 years. The DETECT algorithm can then be useful to identify patients at risk for PAH (http://detect-pah.com). The decision to perform a right heart catheterization requires multidisciplinary coordination with cardiologists and pneumologists.
