Attempts at measuring pulmonary arterial pressure by means of Doppler echocardiography in patients with chronic lung disease
Why the study?
Does Doppler echocardiography accurately measure pulmonary arterial pressure compared to right heart catheterization in patients with chronic lung disease?
Population
72 patients with severe chronic pulmonary or pulmonary vascular disease
Comparison
Continuous wave and pulsed wave Doppler… vs Right heart catheterization

Implication
Limits applicability of Doppler pulmonary pressure estimation in chronic lung disease; leaves open validation of reliable non-invasive alternatives to catheterization.
Structured PICO
Does Doppler echocardiography accurately measure pulmonary arterial pressure compared to right heart catheterization in patients with chronic lung disease?
P
Population
72 patients with severe chronic pulmonary or pulmonary vascular disease (43 with pulmonary hypertension, 27 with normal pressure)
I
Intervention
Continuous wave (CW) and pulsed wave (PW) Doppler echocardiography
C
Comparator
Right heart catheterization
O
Outcome
Correlation of Doppler echocardiography measurements with pulmonary arterial pressuresurrogate
While specific Doppler echocardiography parameters correlate with pulmonary arterial pressure, no single method is both easily applicable and accurate in patients with chronic lung disease.
Limitations
- No single Doppler method is at the same time easily applicable and accurate in prediction of pulmonary arterial pressure in patients with chronic lung diseases
