Three-Dimensional Echocardiographic Evaluation of Right Ventricular Volumes and Functions in Normal Egyptian Children

Abstract

he aim of our study was to establish normal reference values for right ventricle assessment by three-dimensional Echocardiography in Egyptian children age 6 to 12 years. Our Study included 450 normal healthy Egyptian children who were referred for right ventricular function evaluation by 2 dimensional (2DE) and 3 dimensional echocardiography (3DE). Out of these 450 patients, 435 (96%) subjects had good echogenic window and were feasible for assessment by the GE 4D Auto RVQ software for analysis. The subjects included in our study were 229 females (52.6%) and 206 males (47.4%), age ranging from 6 to 12 years with mean age of 9.478 years. The subjects’ body surface area ranged from 0.74 to 1.57m2 with a mean BSA of 1.153m2. Subjects were subdivided into 2 subgroups. Group 1 included 177 subjects, 93 females (52.6%) and 84 males (47.4%) with age range from 11 to 12 years with mean age of 11.6 years and with a mean BSA of 1.344m2. Group 2 included 258 subjects, 136 females (52.7%) and 122 males (47.3%) with age range from 6 to 10 years with mean age of 8 years and with a mean BSA of 1.022m2. The normal ranges of absolute and BSA-indexed values of RV volumes and RV EF were measured and percentile curves were plotted against different age groups for boys and girls.
