Tricuspid Annular Plane-Systolic Excarsion pada Bayi Kurang Bulan dan Cukup Bulan
A preterm infant is a baby born with gestational age less than 37 weeks. Preterm babies tend to have problems compared to normal ones. Premature gestational age might result in immaturity of all organ systems of the body including cardiovascular organs. The aim of this study was to find out the right ventricle function by tricuspid annular plane systolic excursion (TAPSE) and left ventricle by ejection fraction and shortening fraction using echocardiography on preterm babies. The subject of this study were term and preterm babies who fulfilled the inclusion criteria: appropiate gestational age babies 3–30 days old. This was an analytic descriptive study with cross-sectional method held in Department of Child Health Dr. Hasan Sadikin Hospital Bandung during July–October 2010, and statistical analysis using t–test Spearman rank correlation test. The result of the study showed that the right ventricle function examined by TAPSE method was different on preterm compared to term babies
(p=0.006). No significant difference was found in the ejection fraction between preterm and term babies (p=0.22) and so did the shortening fraction (p=0.20). It was concluded that there is a difference in the right ventricle function by TAPSE method between preterm (lower) and term babies. [MKB. 2011;43(4):178–82].
