摘要

Background: Previous studies have shown that preoperative left ventricular (LV) ejection fraction, LV end-systolic diameter (LVESD), presence of atrial fibrillation and symptoms were good predictors of LV dysfunction after mitral valve repair (MVr). However, LV global longitudinal systolic strain (GLS) has been recently proposed as novel and sensitive measurement of latent LV dysfunction. The aim of this study was to investigate the value of GLS,measured by 2D speckle tracking analysis, as independent predictor of postoperative LV dysfunction.
