- Echocardiogram Criteria For Severe Aortic Valve Disease
When the aortic valve does not fully close, blood reverses direction and appears as a jet, or plume, on the screen How far the jet extends also helps determine the severity of the regurgitation
- Aortic stenosis - Echocardiography, diagnosis, grading . . .
Aortic stenosis is a progressive disease that leads to a gradual reduction in the orifice area As the area is reduced, transvalvular flow resistance increases This results in increased left ventricular load, while simultaneously affecting systemic perfusion Aortic stenosis is a serious condition with poor long-term outcomes
- Grading aortic stenosis severity when the flow modifies the . . .
Valvular aortic stenosis (AS) is the most frequent valvular disease in developed countries The diagnosis of AS is classically confirmed by echocardiography, the standard tool for detecting and assessing the severity of the disease (1) Nevertheless, assessment of AS severity is still challenging
- Aortic valve stenosis: evaluation and management of patients . . .
Echocardiographic assessment of the severity of aortic valve stenosis (AS) usually relies on peak velocity, mean pressure gradient (MPG) and aortic valve area (AVA), which should ideally be concordant In 20%-30% of patients, these parameters are discordant (usually AVA <1 cm² and MPG <40 mmHg)

Normal Doppler echocardiographic values of aortic valve prosthesis Adapted from Perrino et al Perrino
- Aortic Valve Area by Velocity Ratio - E-Echocardiography
How to get an AVA by Velocity Ratio Measure the LVOT diameter in centimeters The optimal view is a maximally zoomed view of the midesophageal AVLAX The gain and compress should be set so the endomyocardial wall of the LVOT is clearly discernable
- NORMAL AORTIC VALVE VELOCITY RATIO DIFFERS BY RACE AND GENDER
The aortic valve velocity ratio (AVVR) is defined as the peak left ventricular outflow tract (LVOT) Doppler velocity divided by the maximal aortic valve (AV) velocity
