ABSTRACT
BACKGROUND:
Grading the severity of aortic regurgitation (AR) is very important for clinical follow-up. In AR, left atrial (LA) mechanics can be affected in time and LA strain variations can be illuminating for the grading of AR. The purpose of this study is to determine whether the LA strain parameters are associated with the severity of AR or not.METHODOLOGY:
Sixty-four consecutive patients with AR were included in this study. Patients divided into three groups as mild (n 22), moderate (n 15), or severe (n 27). All patients' LA strain measurements were performed and results were compared between groups.RESULTS:
Between the groups, LA reservoir (LA-Res) in the mild, moderate, and severe AR groups was 42.0 ± 18.0, 41.4 ± 14.8, and 29.2 ± 6.0, respectively (P 0.002) and LA pump in the mild, moderate, and severe AR groups was 21.2 ± 8.7, 19.3 ± 7.4, and 13.1 ± 4.4, respectively (P < 0.001), different, while no difference was noticed on LA SRs, LA SRe, and LA SRa.CONCLUSION:
This study showed that LA-Res and LA pump parameters of the patients with severe AR significantly decreased compared to those of the mild and moderate AR group. The grading of the LA mechanics in patients with chronic AR might provide a supplementary contribution to the present parameters in the grading of AR.
