Doppler Echocardiography in Adults With Symptomatic Aortic Stenosis
Why the study?
Does a Doppler echocardiography-based clinical prediction rule accurately predict the need for aortic valve replacement and reduce costs compared to an invasive diagnostic approach in adults with symptomatic aortic stenosis?
Population
103 adults undergoing cardiac catheterization for suspected symptomatic aortic stenosis, mean age 69 years.
Comparison
Doppler echocardiography using a clinical… vs Invasive diagnostic approach.

Overview
May reduce catheterization needs and costs in symptomatic AS; leaves open prospective validation before practice change.
Structured PICO
Does a Doppler echocardiography-based clinical prediction rule accurately predict the need for aortic valve replacement and reduce costs compared to an invasive diagnostic approach in adults with symptomatic aortic stenosis?
P
Population
103 adults undergoing cardiac catheterization for suspected symptomatic aortic stenosis, mean age 69 years.
I
Intervention
Doppler echocardiography using a clinical prediction rule based on maximum aortic jet velocity (Vmax) and Doppler aortic valve area (AVA).
C
Comparator
Invasive diagnostic approach (cardiac catheterization).
O
Outcome
Need for aortic valve replacement (AVR).
A Doppler echocardiography-based clinical prediction rule accurately identifies the need for aortic valve replacement in symptomatic aortic stenosis, potentially reducing the need for invasive catheterization and lowering diagnostic costs.
