Mg. Russo et al., ECHOCARDIOGRAPHIC EVALUATION OF LEFT-VENTRICULAR SYSTOLIC FUNCTION INTHE DOWN-SYNDROME, The American journal of cardiology, 81(10), 1998, pp. 1215
Left ventricular systolic function was evaluated by echo-Doppler in 22
Down syndrome patients without congenital heart disease. Although the
y had evident left ventricular hyperkinesia, this did not appear to re
flect intrinsic abnormalities of myocardial properties but a reduced a
fterload.
