Background: In the United States, stroke is the third leading cause of mortality and one of the leading causes of permanent disability. Previous studies have revealed that cardioembolic strokes account for 15–30% of ischemic strokes, making cardiac assessment critical in these individuals.
Low ejection fraction (EF) and severe valvular disease are the most prevalent causes of cardiac embolism. When it comes to determining the cause of cardiac embolism, TEE is the best imaging technique. For the majority of patients, invasive LA function measures aren't an option. TEE data in patients with primary valvular heart disease were used to examine the relationship between the LA functional parameter and the LAA function. Methods: In the cardiology department, a cross-sectional single-center research was conducted. Patients with known valvular heart disease were included in the study. We found that the mean age of the participants in our research was 44.1613.59, and there was no statistically significant difference in the prevalence of hypertension, diabetes, or smoking. It has been shown that the LAA velocity and the LA maximum system strain (r= 0.615; P 0.001), strain rate (r= 0.623) are strongly linked. TDI-derived peak sys strain correlated well with LAA velocity, as did the peak strain rate
