How to calculate Left Ventricular End Diastolic Pressure.
Obtain a PWD/CWD of the long axis view of the aortic valve. An aortic regurgitant jet is required to perform this calculation. An AR jet will decay throughout diastole. The end-diastolic velocity is called Vmin. At the end of diastole record the diastolic blood pressure. Vmin represents the gradient across the aortic valve at the end of diastole. Subtracting this gradient from the diastolic blood pressure will yield the LVEDP.
