WebPatients were classified into 4 groups (high-gradient/normal flow [HGNF], high-gradient/low flow [HGLF], low-gradient/normal flow [LGNF], and low-gradient/low flow [LGLF]). Low flow was defined as stroke volume index <35 mL/m (2) and low gradient as a mean aortic gradient <40 mm Hg. WebNov 1, 2024 · Aortic stenosis (AS) is the most common valvular heart disease and the main indication for valvular replacement in older women. Correct AS grading is mandatory for an adequate selection of patients for both surgical and …

WebJan 28, 2012 · In patients with an AVA <1 cm2, four flow-gradient AS categories can be identified: normal flow/low gradient (NF/LG), normal flow/high gradient (NF/HG), low flow/high gradient (LF/HG) and low flow/low gradient (LF/LG). LF is defined as an indexed LV stroke volume <35 mL/m2and LG as a mean trans-aortic pressure gradient <40 … WebMay 6, 2024 · The current definition of severe AS is made on the basis of typical findings on physical examination, in conjunction with hemodynamic criteria of a mean pressure gradient (MG) ≥40 mm Hg and a calculated aortic valve area (AVA) ≤1.0 cm 2.
