BACKGROUND: This study aimed to explore whether echocardiographic measurements during the early postoperative period can predict persistent @entity1002 ( @entity1002 ) after aortic valve surgery in @entity1 with chronic @entity337 ( @entity337 ). METHODS: We prospectively recruited 54 @entity1 (59      12  years) with isolated chronic severe @entity337 who subsequently underwent aortic valve surgery. Standard transthoracic echocardiography was performed before the operation, during the early postoperative period ( <=2  weeks), and then 1  year after the surgery. RESULTS: Twelve @entity1 with preoperative @entity1002 demonstrated @entity1002 at early after the surgery. Of the 42 @entity1 without @entity1002 at preoperative echocardiography, 15 @entity1 (36%) developed early postoperative @entity1002 after surgical correction. All 27 @entity1 without @entity1002 at early postoperative echocardiography maintained LV function at 1  year after surgery. In the other 27 @entity1 with postoperative @entity1002 , 17 @entity1 recovered from @entity1002 and 10 @entity1 did not at 1  year after surgery. Multiple logistic analysis demonstrated that postoperative left atrial volume index (LAVI) was the only independent predictor for persistent @entity1002 at 1  year after surgery in @entity1 with postoperative @entity1002 (OR 1.180, 95% CI, 1.003-1.390, P  =  0.046). The optimal LAVI cutoff value (>34.9  mL/m(2) ) had a sensitivity of 80% and a specificity of 88% for the prediction of persistent @entity1002 . CONCLUSION: Prevalence of early postoperative @entity1002 was relatively high, even in the @entity1 without @entity1002 at preoperative echocardiography. Postoperative LAVI could be useful to predict persistent @entity1002 after aortic valve surgery in @entity1 with early postoperative @entity1002 .
