is the peak-to-mean pressure gradient ratio useful for assessment of aortic valve prosthesis obstruction?
background: the evaluation of prosthetic valves is very difficult with two-dimensional transthoracic echocardiography alone. doppler and color flow imaging as well as transesophageal echocardiography are more reliable to detect prosthetic valve dysfunction. however, doppler study sometimes tends to be misleading due to the load-depending characteristics of peak and mean pressure gradients. the ...

متن کاملPremature opening of aortic valve in severe aortic regurgitation.
Premature opening of the aortic valve in late diastole has been demonstrated by echocardiography in a patient with severe aortic regurgitation. Valve opening coincided with the end of the diastolic murmur and equalization of aortic and left ventricular diastolic pressures. Echocardiography of the aortic valve in severe aortic reflux may, therefore, provide valuable information about the underly...
متن کاملNomograms for severity of aortic valve stenosis using peak aortic valve pressure gradient and left ventricular ejection fraction.
AIMS Continuity equation to evaluate aortic valve area (AVA(CE)) is critically dependent on accurate measurement of left ventricular outflow tract diameter and velocity. To circumvent these limitations, the present study aimed to generate nomograms for a facilitated estimation of aortic valve area using peak aortic valve pressure gradient (DeltapAv) and left ventricular ejection fraction (LVEF)...
متن کاملMid-diastolic aortic valve opening in severe acute aortic regurgitation.
A case of severe acute aortic regurgitation is reported. Echocardiographic findings included mid-diastolic opening of the aortic valve, premature closure of the mitral valve, diastolic shuddering of the anterior mitral leaflet, probable demonstration of the flail aortic cusp in the left ventricular outflow tract, and increased left atrial and left ventricular dimensions. Correlation with hemody...
