Abstract
During ventricular systole the aortic root (Ao) moves anteriorly and inferiorly. There is no study available to detect a possible relationship between the Ao anterior motion and left ventricular contractile state (LVC) by echocardiography (E). Thus, we studied 100 normal children with body surface area ranging from 0.7 to 1.2 by E to compare the anterior Ao motion (AoA) with shortening fraction (SF) of the LV and the systolic thickening amplitude of the posterior LV wall (LVWA). Standard E were obtained of the Ao and LV from the 3rd and 4th left intercostal space on strip chart recordings. AoA was measured as the vertical distance in millimeters between end-diastole and end-systole for the posterior wall. Also vertical LVWA was measured in millimeters at the point of maximum systolic excursion. SF was calculated by previously described methods. Our results for the mean and 1 standard deviation were as follows:
The r value was <0.4 for the comparison between (a) and (b) as well as (a) and (c). From this we feel that although Ao anterior motion occurs during LV systole, it is not directly related to LVC by E.
