Diagnostic Pitfalls

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
