Mechanisms predisposing to LVOTG induction. A-Left ventricular hypertrophy – particularly basal septal segment (HCM, hypertension, storage disease). B-LV hypercontractivility (moderate tachycardia). C-Small size LV cavity (HCM, children, women, dehydratation). D-Prolonged/Thickened mitral leaflet(s). E-Reduced LV preload (dehydratation, diuretics, vasodilators, hemodialysis, fever, septic shock).
