Of the 42 patients without LVSD at preoperative echocardiography, 15 patients (36%) developed early postoperative LVSD after surgical correction. All 27 patients without LVSD at early postoperative echocardiography maintained LV function at 1\u00a0year after surgery. In the other 27 patients with postoperative LVSD, 17 patients recovered from LVSD and 10 patients did not at 1\u00a0year after surgery. Multiple logistic analysis demonstrated that postoperative left atrial volume index (LAVI) was the only independent predictor for persistent LVSD at 1\u00a0year after surgery in patients with postoperative LVSD (OR 1.180, 95% CI, 1.003\u20131.390, P\u00a0=\u00a00.046). The optimal LAVI cutoff value (&gt;34.9\u00a0mL\/m<jats:sup>2<\/jats:sup>) had a sensitivity of 80% and a specificity of 88% for the prediction of persistent LVSD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Prevalence of early postoperative <jats:styled-content style=\"fixed-case\">LVSD<\/jats:styled-content> was relatively high, even in the patients without <jats:styled-content style=\"fixed-case\">LVSD<\/jats:styled-content> at preoperative echocardiography.
