Researchers have developed a novel method for predicting left ventricular ejection fraction (EF) using parasternal long-axis (PLAX) echocardiography, addressing the scarcity of labeled data in this area. By correlating clinical notes with echocardiographic videos and employing view classifiers, they created a dataset of over 25,000 PLAX videos. The resulting model achieves a mean absolute error (MAE) of 6.86%, demonstrating the clinical relevance and feasibility of PLAX-based EF estimation, which rivals the performance of the current clinical standard using apical four-chamber views. Further improvements were observed by integrating PLAX and A4C predictions, leading to a 6.37% MAE. AI
