Abstract
The right ventricular longitudinal strain (RVLS) usually measure by cardiac magnetic resonance imaging (CMRI). But an Echocardiography was superior in portability, not expensive and spent time less than MRI. In adult patient, the RVLS able to describe right ventricle myocardial function and several use in research and clinical routine than the child group. This study aim to retrospective study in RVLS from pediatric echocardiographic reports and compare value in tree segments and age group. This retrospective study review echocardiographic data in RVLS data from Philips Epiq CVX by transducer S8-3 MHZ and X5-1 MHZ with auto RV strain function in Automatic cardiac myocardial quantification mode (aCMQ) and use offline analysis by Philips heath care system QLAB version 15.0 in normal child and adolescent 45 patients. Age 1-18 years old (6.5 ± 6.4). Female 33% and male 67%. The result was occurred at Basal RVLS -29.7 ± 7.9% [95% CI (-27.3 to -32.1%)], Mid RVLS -24.8 ± 6.0% [95% CI (-23 to -26.6%)], Apical RV LS -21.8% ± 5.0% [95% CI (-20.3 to -23.3%)], RV FWSL -25.7 ± 5.6% [95% CI (-24 to -27.4%)], RV 4CSL -21.3 ± 5.2% [95% CI (-19.3 to -22.9%)]. And the significant difference in RVLS in the under versus above 10 years group, similar significant difference of 3 segments (Basal, Mid, Apical) (P-value < 0.05)
