WebBackground— Nonobstructive hypertrophic cardiomyopathy (HCM) has been regarded as the predominant hemodynamic form of the disease on the basis of assessment of outflow gradient under resting conditions. We sought to prospectively define the prevalence, clinical profile, and significance of left ventricular (LV) outflow tract obstruction under resting … WebThese findings suggest that acceleration of left ventricle flow toward the mitral valve in systole is only recorded when there is hemodynamically significant mitral regurgitation …

When the LVOT velocity is ≥ 1.2 m/s then the maximum and mean AV gradients must be corrected. The corrected maximum pressure gradient (DPc) can be calculated from the expanded Bernoulli equation (Eq. 1.5) where V 2 is the peak aortic velocity and V 1 is the peak LVOT velocity: DPc = 4 ...
