Jet width of lvot
WebJet length/velocity ratio is calculated as the ratio of maximum jet penetrance to mean velocity of regurgitant flow. Jet length/velocity ratio was significantly higher in patients with severe aortic regurgitation (2.03 ± 0.53) compared to patients with less than severe aortic regurgitation (1.24 ± 0.32, P < 0.001).

Web30 okt. 2024 · The ratio of the jet width to the left ventricular outflow tract (jet width/LVOT) ratio was also measured in parasternal long-axis view. The effective regurgitant orifice area (EROA) was calculated using the proximal isovelocity surface area (PISA) method. WebAlternatively, the cross-sectional area (CSA) can be calculated from the jet width and then used in a ratio to the LVOT area. AR jet interrogation by color Doppler has limitations because of the 3D nature of AR jets and the LVOT. Thus, elliptical, eccentric, and multiple AR jets are poorly assessed by this method.
