SHORT EDITORIAL

Low-Flow Low-Gradient and Low-Ejection Fraction Aortic Stenosis and Projected Aortic Valve Area Calculation: So Important but so Complicated. Let us Just Keep it Simple!

Wilson Mathias Junior



Figure 1 – Alternative flow calculation formula where: Qalternative is flow in mL/s, ASTLVOT is the sectional transverse area of the left ventricular outflow tract (LVOT) in cm2, and VmeanLVOT is the mean blood flow velocity by pulsed wave Doppler at the LVOT level during left ventricular ejection, being expressed in m/s.





Keywords: Aortic Valve Stenosis / surgery; Stroke Volume; Echocardiogrphy, Stress / methods..
