Speckle tracking echocardiography (STE<\/jats:styled-content>) has been applied recently for evaluation of LA<\/jats:styled-content> function. The purpose of this study was to examine whether left atrial longitudinal strain measured by STE<\/jats:styled-content> is a predictor for the development of POAF<\/jats:styled-content> following mitral valve surgery for severe mitral regurgitation. We studied 53 patients undergoing mitral valve surgery in sinus rhythm at the time of surgery. Echocardiography with evaluation of LA<\/jats:styled-content> strain by STE<\/jats:styled-content> was performed. Detection of POAF<\/jats:styled-content> was based on documentation of AF<\/jats:styled-content> episodes by continuous telemetry throughout hospitalization. Patients who did not develop POAF<\/jats:styled-content> were taken as group 1 and those who had POAF<\/jats:styled-content> constituted group 2. The echocardiographic and clinical predictors of POAF<\/jats:styled-content> were investigated. POAF<\/jats:styled-content> occurred in 28.3% of subjects. Mean age, LAV<\/jats:styled-content>i and BNP<\/jats:styled-content> were found higher in group 2 while peak atrial longitudinal strain (PALS<\/jats:styled-content>) (13.9\u00a0\u00b1\u00a03.8% vs. 24.8\u00a0\u00b1\u00a07.3%; P\u00a0<\u00a00.001), peak atrial contraction strain (PACS<\/jats:styled-content>) (7.6\u00a0\u00b1\u00a01.95% vs. 11.3\u00a0\u00b1\u00a03.5%; P\u00a0<\u00a00.001) were significantly lower. By multivariate logistic regression analysis, PALS<\/jats:styled-content> and LAV<\/jats:styled-content>i were independent predictor of POAF<\/jats:styled-content> development. LA<\/jats:styled-content> longitudinal strain was found to predict POAF<\/jats:styled-content> in patients undergoing mitral valve surgery. It could be used to better identify patients at greater risk of developing POAF<\/jats:styled-content>, and thus to guide in risk stratification and to take appropriate intensive prophylactic therapy.<\/jats:p><\/jats:sec>","DOI":"10.1111\/echo.12222","type":"journal-article","created":{"date-parts":[[2013,4,19]],"date-time":"2013-04-19T09:25:46Z","timestamp":1366363546000},"page":"1061-1068","source":"Crossref","is-referenced-by-count":56,"title":["Left
