Low-flow low-gradient aortic stenosis however is an especially challenging subset as valve replacement has a significant risk and may fail to alleviate symptoms or improve left. Aortic stenosis AS is the most frequently observed valvular heart disease.
Low flow low gradient aortic stenosis is a highly challenging condition in terms of diagnosis and therapeutic management. True-severe classical and paradoxical low-flow low-gradient. Low-flow low-gradient aortic stenosis LFLG AS is an echocardiographic entity defined by a mismatch between a reduced aortic valve area AVA 1 cm 2 and a non-severe.
In these patients the low flow state is generally related to a pronounced LV concentric r. An important proportion of patients with aortic stenosis AS have a low-gradient AS ie. Low-flow low-gradient aortic stenosis LFLG AS with reduced left ventricle ejection fraction LVEF is still a diagnostic and therapeutic challenge.
Authors Eric Awtry 1 Ravin Davidoff. Request a Consultation with a Cleveland Clinic Heart Specialist. The occurrence of low-flow low-gradient severe aortic stenosis in patients with normal left ventricle LV ejection fraction has only been recently described.
