Abstract

Background: One common complication of cardiac surgeries is post-operative atrial fibrillation (POAF), which can have a detrimental effect on the patient's prognosis. The evidence that was examined here, however, points to the notion that illnesses and frailty are predisposing variables that cause atria remodeling and, in turn, promote POAF. These events are caused by oxidative damage, inflammation, fibrosis, and apoptosis, together with electrical remodeling in the atrium.

Aim and objectives: Among patients undergoing mitral valve replacement for mitral valve disease, the goal is to determine which echocardiographic variables are predictive of post-operative atrial fibrillation.

Subjects and methods: This research was performed on 80 cases of mitral valve disease referred to the Luxor International Hospital outpatient clinic for mitral valve replacement from December 2021 to February 2023 for evaluation.

Results: There were significant differences as regard echocardiographic data, POAF LAAPD(p-value = 0.02), LALD(p-value = 0.001), LATD(p-value = 0.001), LA EF(p-value = 0.028), LA Min volume(p-value = 0.001), LA Max volume(p-value = 0.001), LAVI(p-value = 0.003), E(p-value = 0.003), E/E\(p-value = 0.003), PASP(p-value = 0.005), Mean LS(p-value = 0.001) and Mean GLS(p-value = 0.001) and Laboratory data as regard POAF CRP(p-value = 0.001), K(p-value = 0.001), Ca(p-value = 0.001), Create(p-value = 0.001), Urea(p-value = 0.001), AST (p-value = 0.001) and ALT(p-value = 0.001).

Conclusion: Strain measurement is a straightforward, reliable, and repeatable technique for assessing LV and LA function. Comparing LV and LA strain parameters to traditional ventricular atrial function parameters, the former are more sensitive
