Clinical value of Doppler echocardiography in the assessment of adults with aortic stenosis.
Why the study?
Does continuous wave Doppler echocardiography accurately assess stenosis severity compared to cardiac catheterisation in adults with suspected aortic stenosis?
Population
41 adults with clinically suspected aortic stenosis undergoing cardiac catheterisation
Comparison
Continuous wave Doppler echocardiography… vs Cardiac catheterisation

Implication
Supports Doppler for aortic stenosis severity assessment; hypothesis-generating before deferring routine preoperative catheterization.
Structured PICO
Does continuous wave Doppler echocardiography accurately assess stenosis severity compared to cardiac catheterisation in adults with suspected aortic stenosis?
P
Population
41 adults with clinically suspected aortic stenosis undergoing cardiac catheterisation
I
Intervention
Continuous wave Doppler echocardiography combined with clinical examination, electrocardiograms, chest radiographs, and cross-sectional echocardiography
C
Comparator
Cardiac catheterisation
O
Outcome
Correlation of transvalvular gradients and identification of surgically significant stenosessurrogate
Continuous wave Doppler echocardiography accurately identifies surgically significant aortic stenosis, suggesting surgery can be recommended without the need for routine preoperative cardiac catheterisation.
