Figure 1.. Effects of manual tracing and view acquisition errors on measured left ventricular ejection fraction
Absolute changes in calculated left ventricular (LV) ejection fraction after systematic introduction of varying degrees of common tracing and view acquisition errors, including errors in (A) choice of end systolic volume (ESV) frame, (B) angle of left ventricular longitudinal axis, (C) foreshortening of the left ventricular apex, (D) mitral valve (MV) annulus level, and (E) tracing of the endocardial borders.
