Why the study?
Can a noninvasive ultrasound-based method analyzing heart wall vibrations estimate left-ventricular end-diastole elasticity in human patients?
Can a noninvasive ultrasound-based method analyzing heart wall vibrations estimate left-ventricular end-diastole elasticity in human patients?
A novel noninvasive ultrasound-based method combining phased tracking and short-time Fourier transform can be used to estimate left-ventricular end-diastolic elasticity in vivo.
Supports noninvasive LV elasticity estimation in humans; leaves open validation and clinical utility in diastolic assessment.
A new noninvasive method was previously presented for the measurement of the left ventricular (LV) end-diastolic pressure (EDP) by combining Mirsky's method and the experimentally derived relationship. The eigenfrequency was determined by applying a short-time Fourier transform to the velocity signal on the human heart wall which is transcutaneously measured in vivo by the phased tracking method using ultrasound. In the Letter the authors estimate the elasticity of the heart wall for several human patients.
