Moderate AS, AR – Continuous wave Doppler Aortic stenosis jet has a peak gradient of 61 mm Hg and mean gradient of 33 mm Hg. Peak gradient derived

Ventriculo-arterial pressure gradient It is usually the peak to peak gradient which is measured from pressure tracing during cardiac catheterisation, while Doppler echocardiography measures the peak instantaneous gradient.
