Assessment of global longitudinal strain by speckle tracking echocardiography in patients with severe primary mitral regurgitation
Main Article Content
Abstract
Background: In asymptomatic patients with severe primary mitral regurgitation (PMR), early detection of left ventricular (LV) dysfunction indicates the optimal timing of mitral valve surgery and predictes impaired postoperative LV function.
Objectives: Evaluation long longitudinal strain by Speckle Tracking in Patients with Severe Primary Mitral Regurgitation
Methods and results: 35 preoperative patients with severe PMR and 25 age-matched healthy subjects at Hanoi Heart Hospital from June 2018 to September 2019. Patients with PMR had longitudinal dysfunction by comparison with controls, although EF were similar.
Mean global myocardial longitudinal strain (GLS avg) has a linear correlation with FS (r² = 0.127, p <0.05) and EF biplane (r² = 0.216, p <0.005).
Conclusion: Longitudinal LV deformation assessed by speckle tracking can detect subclinical LV dysfunction and predict impaired postoperative LV function in asymptomatic patients with severe PMR.
