Predictors of Left Ventricular Dysfunction After Surgery for Degenerative Mitral Regurgitation

Prediction of postoperative ventricular dysfunction is performed using preop LVEF prior to mitral valve surgery for degenerative mitral regurgitation. In this study the utility of LV strain as a predictor of ventricular dysfunction after mitral surgery was assessed. Preoperative RV, LV, and LA strain were strongly associated with postoperative LV dysfunction, and may prove useful in timing of surgery for degenerative mitral regurgitation.
