%X Objective: The aim of this study was to predict mid-term left atrial reverse remodeling after mitral valve surgery. Patients and Methods: Echocardiographic data was obtained preoperatively and at follow-up from 105 patients who underwent mitral valve surgery. Left atrial volume (LAV) was decreased by >30% from baseline in 43 patients (group A), but not in 62 patients (group B). Results: Patients in group A were younger (p = 0.0029). Male was more (p = 0.05) and prosthesis size was bigger in group A (p = 0.005). Only age was a predictor of left atrial reverse remodeling in a logistic regression model (OR = 0.93, 95% CI 0.88 - 0.99; p = 0.03). Late mean trans-mitral pressure gradient was lower in group A than in group B (p = 0.01). There was a weak correlation between the change in left ventricular end-diastolic diameter (LVDd) and LAV (correlation coefficient 0.27, 95% CI 0.07 - 0.45; p = 0.008). Survival and freedom from major adverse cardiac events did not differ between the groups (p = 0.31 and p = 0.87 by log-rank test). Conclusions: Age was the only predictor of left atrial reverse remodeling. There was a weak correlation between changes in LVDd and LAV.
