Onyx aortic valve gradients
WebCurrent practice is to average at least five consecutive cardiac cycles during atrial fibrillation when assessing transvalvular gradients, effectively concealing high … WebElevation in mean transvalvular gradient is a finding that has a variety of etiologies. One such etiology is the pressure-recovery (PR) phenomenon, a consequence of stream convergence and energy conversion across a narrowing, which is an artifact of Doppler echocardiographic calculations of valvular flow.
