Low-flow, low-gradient (LF-LG) aortic stenosis (AS) may occur with depressed or preserved left ventricular ejection fraction (LVEF), and both situations are among the most challenging encountered in patients with valvular heart disease. In both cases, the decrease in gradient relative to AS ...

Many patients with severe aortic stenosis have a "low-flow, low-gradient" aortic stenosis. The management of these patients can be quite difficult, as these patients often show impairment of the left ventricle, which can lead to false measurements of the severity of stenosis and also leads to...
doi:10.1001/jamacardio.2018.4320 Key Points Question What outcomes do patients with low-flow, low-gradient aortic stenosis (LFLG AS) and severely depressed left ventricular function (<30%) experience after transcatheter aortic valve replacement (TAVR)? Findings This multicenter registry study of 293 ...

Background Patients with low-flow, low-gradient (LFLG) aortic stenosis (AS) have precarious hemodynamics and are a fragile population for intervention. Quantification of aortic valve calcification (AVC) severity is a critical component of the evaluation for transcatheter aortic valve replacement (TAVR...
