🆕📝optimal cutoff points for severe AS vary by range of LVEF (<35%, 35%-50%, >50%)
bit.ly/3NVYGfU
🫀If LVEF <35%, use MG of 30 rather than 40 for severe AS
🫀MG & Vmax better than AVA in Dx severe AS adjudicated by C-CT
🫀In LG AS w LVEF <35%, DSE finds contractile reserve in 2/3 patients
🫀If LVEF 35-50%, DSE finds CR in 1/2 patients
🫀1/3 pts had paradoxical LG AS w LVEF >50% yet still got DSE(?)
🫀1/4 pts labeled pseudo-severe AS by DSE had true severe AS by C-CT(not validated in LF)
