Background: Despite improvement in the surgical procedure and strictly following the guidelines for mitral valve replacement (MVR), left ventricular dysfunction still occurs. Novel echocardiographic indices can predict development of LV (left ventricle) dysfunction post MVR. LV-GLS (global longitudinal strain) derived from speckle tracking echocardiography, has been proposed as a novel measure to better depict latent LV dysfunction.
A total of 100 patients with severe MR (mitral regurgitation) planned for MVR were included. Speckle tracking echocardiography was performed at baseline and at follow up post MVR. ROC (Receiver operating characteristics) curve was plotted to derive the cutoff value of LV-GLS for prediction of LV dysfunction post MVR. Univariate and multi variate regression was analyzed to predict the independent predictors of LV dysfunction after MVR.
Results: LV-GLS was decreased from baseline data (-19.9 vs. -17.7) in patients with LVEF
Conclusion: A GLS value of less than -19% was demonstrated as an independent predictor of short term LV dysfunction after mitral valve surgery, LVESD ≥40mm was also verified additional parameter to predict the LV dysfunction post MVR.
