Continuous wave doppler pre-attenuation velocity envelope: a promising tool for the echocardiographic assessment of aortic stenosis

The pre-attenuation velocity envelope is attainable in the majority of patients with aortic stenosis. The pre-attenuation velocity envelope recorded from the 5-chamber view exhibits a noteworthy correlation and agreement with PW Doppler LVOT velocity. This observation positions pre-attenuation velocity envelope as a promising alternative and plausibility check for hemodynamic assessment in patients with aortic stenosis.
