Study Limitations
Our study was a single-centre cross-sectional study. However, a follow-up with an evaluation of the same parameters would be more informative to gain a more comprehensive understanding of the reproducibility of LAAWV in this group of patients. It is essential to acknowledge that certain parameters of LAA function can be influenced by factors such as age, heart rate, and hemodynamic status, However, controlling these factors in a clinical study can be challenging. This study mainly focused on patients with heart failure with reduced ejection fraction. Therefore, it is important to note that the result of this study cannot be generalized to other patients with heart failure with preserved ejection fraction.
