Accuracy of doppler echocardiography in measuring right-heart pressure in patients with pulmonary hypertension

The assessment of pulmonary pressure is of great clinical importance not only for diagnostic purposes, but also for prognosis in patients with pulmonary arterial hypertension. The present study was undertaken on a consecutive basis with a group of patients who had had a previous diagnosis of pulmonary hypertension based on echocardiography, and were referred to our institute. The aim of this study was to determine how accurate Doppler echocardiography is in measuring right-heart pressures.
