Abstract
The amplitude of the anterior mitral leaflet (AML) in the echocardiogram (E) depends on the size of the AML, free flow across the mitral apparatus and the left ventricular (LV) end-diastolic volume. Under normal conditions, it is possible that there is a constant relationship between these factors. To assess this relationship between AML and LV end-diastolic diameters (LVD), we studied 200 normal children between 5-14 years of age with body surface area (BSA) of 0.7 to 1.59. Strip chart E were obtained of the LV in the standard fashion by means of a 2.25 M Hz transducer. Inner LVD was measured in millimeters at the onset of the Q wave of the EKG. Maximum vertical AML amplitude between C and E points was also measured in millimeters. The ratio between AML and LVD was calculated. Our results for the mean and 1 standard deviation were as follows:
There was no significant difference statistically between these values in these growing children at any BSA. This study shows that there is a narrow range in the ratio between AML and LVD in children. Alterations in the ratio from this normal range may support pathology, even though the AML and LVD are within their own normal values.
