Introduction: Non-invasive assessments of left ventricular (LV) systolic function have traditionally relied on the measurement of fractional shortening (FS) or, more commonly estimations of ejection fraction (EF). However, it is well known that both EF and FS have limited sensitivity for characterizing subclinical abnormalities in LV systolic function. Therefore, advanced image analysis techniques have been developed and validated to assess cardiac tissue deformation in multiple planes and, in turn, provide a more sensitive measure of LV performance. When applied to 2-dimensional speckle-tracking echocardiography, (2D STE) based measures of LV deformation have been shown to add incremental prognostic information beyond EF ,but there{u2019}s inter observer variability for assessments of left ventricular (LV) systolic function. Therefore, the present study was designed to evaluate the reproducibility of 2D and 3D speckle-tracking based LV strain measures. Methods: We examined the inter-observer variability in 2D and 3D speckle tracking for global longitudinal strain(GLS) and global circumferential strain (GCS) methods in 35 normal Egyptian Children with average age (9.2 ± 1.1 ) recruited from general outpatient clinics in Cairo University Children Hospital among children coming for treatment of upper respiratory tract infections. Results: Inter-observer agreement regarding measurement of GLS with 2D echocardiography was -4.51, while for GLS with 3D echocardiography was 0.65. Regarding measurement GCS with 2D echocardiography was -3.22, while for GCS with 3D echocardiography was 2.67
