Abstract

Background This study aimed to explore whether echocardiographic measurements during the early postoperative period can predict persistent left ventricular systolic dysfunction (LVSD) after aortic valve surgery in patients with chronic aortic regurgitation (AR). Methods We prospectively recruited 54 patients (59 ± 12 years) with isolated chronic severe AR 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 patients with preoperative LVSD demonstrated LVSD at early after the surgery. 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 year after surgery. In the other 27 patients with postoperative LVSD, 17 patients recovered from LVSD and 10 patients 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 LVSD at 1 year after surgery in patients with postoperative LVSD (OR 1.180, 95% CI, 1.003-1.390, P = 0.046). The optimal LAVI cutoff value (>34.9 mL/m2) had a sensitivity of 80% and a specificity of 88% for the prediction of persistent LVSD. Conclusion Prevalence of early postoperative LVSD was relatively high, even in the patients without LVSD at preoperative echocardiography. Postoperative LAVI could be useful to predict persistent LVSD after aortic valve surgery in patients with early postoperative LVSD.
