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.
