Echocardiographic Hemodynamics

	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 .
