Aortic valve calcium scoring by MDCT is useful to corroborate stenosis severity when DSE is not feasible or not conclusive7, 8. MDCT has the advantage of being independent of hemodynamics/flow and is applicable to all patients. Moreover, calcium scoring does not require the injection of contrast agents. … See more A low flow state may occur with reduced left ventricular ejection fraction (LVEF) (i.e. Classical Low Flow) or with preserved LVEF (i.e. Paradoxical Low Flow) and it is often associated with … See more This entity is found in about 5-10% of the patients with severe AS2 and it is characterized by a reduced LVEF (<50%) and a discordance between the aortic valve area (AVA<1 cm2 and/or <0.6 cm2/m2, consistent … See more Paradoxical LF-LG AS occurs in 5-15% of patients with AS2 and it is defined as a preserved LVEF (50%), a low LV outflow (i.e. stroke volume index <35 mL/m2), a small AVA (1 cm2 … See more However, several patients have incomplete normalization of flow with DSE and may thus still have discordant AVA-gradient findings at … See more WebImportance In low-flow, low-gradient aortic stenosis (LFLG AS), the ...
