    Abstract:
    OBJECTIVE: To study the value of Xstrain technology in the evaluation of cardiac function in children with tonsil adenoidal hypertrophy (TAH). METHODS: Thirty-five children with TAH (TAH group) and 20 normal age-matched children (control group) were enrolled. The left ventricular wall movement in the vertical, radial and circumferential directions and the right ventricular tricuspid annulus movement were detected using Xstrain technology. RESULTS: The systolic and early diastolic velocities of tricuspid annulus in the TAH group were higher than those in the control group. The systolic and diastolic circumferential velocities of the middle lateral wall and back wall of left ventricular in the TAH group were lower than those in the control group. The systolic and early diastolic vertical velocities of the basement of left ventricular wall in the TAH group were higher than those in the control group. There was no significant difference in the radial velocity between the two groups. CONCLUSIONS: Early changes in the cardiac function can be found by Xstrain technology in children with TAH. Xstrain technology can provide a reliable basis for cardiovascular evaluation in children with TAH.
