Hello, the aortic stenosis can differentiate in 3 parts: 1. high grade aortic stenosis with impaired LV-EF (EF < 50%, SVI < 35 ml/m^2 surface area); the transaortic PGmean in cw will underestimate the grade of aortic stenosis; the continuity-formula can help, but the problem is

Hey everyone! Does anybody know a dimensionless measurement of aortic insufficiency, exspecially in aortic insufficiency with impaired left ventricular myocardial function? We know a dimensionless index of aortic stenosis (V-LVOT/V-aortic valve) derived from continuity equation that h
