Echocardiographic Assessment Of Hemodynamics  
  Critical Reminder On Technique: In order for Doppler measurements to be accurate, the ultrasound beam MUST BE ALIGNED PARALLEL TO THE JET BEING MEASURED. Failure to achieve this alignment will lead to UNDERESTIMATION of the jet velocity.

  Standards And Measures    
  Normal LA Volume Index < 32 ml/m2 BSA    
  LVEF Cutoff values (ASE): <55%, <45%, <30%      
  LVIDd in cm/m2 BSA = 2.4-3.2, 3.5, 3.8    
  Although EF and LV dimensions do not correlate with    
  HF symptoms, exercise capacity, or myocardial oxygen    
  consumption they do provide crucial prognostic    
  information .
