It cannot be emphasized enough that diagnosis and assessment for operability must be carried out by experienced healthcare professionals at expert centers.1
Screening for CTEPH is not common practice. In a pulmonary hypertension (PH) registry, 43% of patients with pulmonary arterial hypertension (PAH) were diagnosed without a ventilation/perfusion (V/Q) scan.2
Screening PH with computer tomography pulmonary angiography (CTPA) often doesn’t recognize CTEPH.3
Patients with CTEPH can present without a history of deep vein thrombosis (DVT) or pulmonary embolism (PE).4
Failure to refer to an expert PH center may result in a patient being wrongly assessed as inoperable.1
