121 Evaluation of a Novel Ultrasound Machine Learning Algorithm in Estimating Left Ventricular Ejection Fraction

Physicians with training in point-of-care ultrasound (POCUS) can reliably estimate left ventricular ejection fracture (LVEF). However, those without experience or at novice level may misestimate LVEF. The reference standard for calculation of LVEF involves obtaining both apical four-chamber (AP4) and apical two-chamber (AP2) views, and tracing the endocardial border. In POCUS, these views are difficult to obtain due to a number of patient,...
