Clinical assessment of the patient with suspected PAH and the role of cardiac catheterization

Show Summary Details

Preview

• The clinical evaluation of PAH includes confirmation of elevated pulmonary artery pressure as well as definition of underlying pathophysiology, aetiology, treatment options and prognosis • An estimate of pulmonary artery systolic pressure is only one component of a complete echocardiographic assessment for PAH. Such estimates have variable accuracy and limited diagnostic and prognostic value in isolation • Cardiac catheterization is indicated in patients with suspected PAH. Elevated mean PA pressure defines PAH, but other parameters such as cardiac output and elevated right sided filling pressures provide key prognostic information.
