DOPPLER-DERIVED RIGHT VEN T RICU L AR MYOC ARD IAL PERFORMANCE IN DEX IN NEON ATES: N ORMAL VALUES

Original Research
Doppler-derived myocardial performance index (MPI) , defined as the s um
of isovolumetric contraction and relaxation durations divided by ejection time, is
an easily measured and reproducible index that shows both systolic and diastolic
myocardial function. The goal of this study was to define normal values of right
ventricular MPI in neonates in the first 48 to 72 hours of life.
Fifty-one quiet or sleeping healthy and term neonates underwent complete
M-mode, two-dimensional color-Doppler echocardiographic examination and RV
MPI was calculated in them. Statistical analysis was performed using SPSS software.
A P value less than 0.05 was considered as significant.
RV MPI was shown to be 0.23±0.14 in healthy neonates. There was no correlation
between RV MPI and either age or weight of the newborn infants. While
this value closely resembles the results of some researchers, it is lower than that
previously reported by other investigators in healthy children. The lower value of
RV MPI in neonates may be possibly related to the higher pulmonary arterial
pressure or right ventricular mass in the first few days of life in neonates. Further
study to evaluate the effect of pulmonary arterial pressure and right ventricular
mass on RV MPI is recommended.
