However, when V 1 is greater than 1 m/s, which may be seen in concomitant AR or a high output state, it should be included in the formula. The mean pressure gradient is derived from the average ...

WASHINGTON, DC—Invasive hemodynamic assessment may help better identify severe aortic stenosis in patients with low aortic flow/low transvalvular pressure gradients and preserved ejection fractions, ...

CHICAGO, IL—Patients undergoing TAVR with a self-expanding supra-annular bioprothesis (CoreValve, Evolut R, or Evolut PRO; Medtronic) have lower aortic valve mean pressure gradients, larger effective ...
