Algorithm for haemodynamic evaluation of suspected pulmonary arterial hypertension in patients aged >65 years.42,43aThis reflects the recommendation from the 6th World Symposium on Pulmonary Hypertension to consider this threshold as the upper limit of normal value.44 Please note the 2015 ESC/ERS Guidelines use the threshold value of 25 mmHg for mean pulmonary arterial pressure measurements.32bConsider left ventricle end-diastolic pressure validation. ECHO, echocardiography; HFpEF, heart failure with preserved ejection fraction; LHC, left heart catheterization; LHD, left heart disease; mPAP, mean pulmonary arterial pressure; PAWP, pulmonary artery wedge pressure; PH, pulmonary hypertension; PVR, pulmonary vascular resistance; RHC, right heart catheterization; WU, Wood units.
