Abstract
: The left ventricular ejection fraction (LVEF) is one of the most important quantitative indicators in cardiovascular medicine. It serves as a key measure for diagnosing, assessing risk, and guiding treatment decisions in conditions such as heart failure, cardiomyopathies, and coronary artery disease. However, obtaining accurate LVEF values using echocardiography remains a major challenge. The process is often affected by differences between observers (8%–15%), time-consuming manual measurements that take several minutes per case, dependence on the operator’s skill
