The presence of depressed RV function, AF, higher LV mass, and lower LVEF is independently associated with low flow in aortic valve stenosis.

Moderate or severe mitral regurgitation was independently associated with low flow in patients with AS and preserved LVEFs.

These associations with low flow are clinically important to recognize, to avoid underestimation of AS severity.
