Abstract
Objectives: Comparing effects of mitral stenosis and mitral regurgitation on LA deformation using twodimensional speckle tracking echocardiography. Methods: Fifty patients with isolated moderate to severe MS, fifty patients with isolated moderate to severe MR and normal left ventricular ejection fraction (EF≥ 55%) were compared using one way analysis of variance (ANOVA) test with two-group comparisons. LA reservoir strain was calculated as peak systolic atrial longitudinal strain, LA reservoir strain rate as peak systolic positive value, LA conduit SR as the early diastolic negative peak, and LA contractile SR as the late diastolic negative peak with QRS onset as the reference point. Results: There was a statistically significant difference between the LA average PALS (p
