The effect of Large for Gestational Age on Asymmetrical Ventricular Septal Hypertrophy in the Newborn.
Yong Soo Kim, Soo Ahn Chae, In Seok Lim, Byoung Hoon Yoo
It has been known for a long time that infants of insulin dependent diabetic mothers are prone to develop macrosornia, organomegaly, hyperbilirubinemia, respiratory distress syndrome, hypoglycemia, hypocalcemia, septicemia and congenital anomalies in the neonatal period. And echocardiographic asymmetrical- ventricular septal hyper- trophy(ASH) has been observed in the newborn infants of diabetic mothers. The etiology of the ASH remains unknown, although fetal hyperglycemia and subsequent glycogen deposits have been postulated as contributing factors. Therefore, we have studied whether large for gestational age(LGA) has played an important role of developing ASH. METHODS: We compared echocardiographic findings in neonates of LGA and appro- priate for gestational age(AGA), who were admitted to the Department of Pediatrics, Chung Ang University Hospital from April 1994 to March 1997. RESULTS: 1) Mean LVED in LGA and AGA were 1.96+0.06cm and 1.94+0.04cm, respectively. 2) Mean LVPW in LGA and AGA were 0.37+0.05cm and 0.370.05cm, respectively. 3) Mean IVS in LGA and AGA were 0.400.09cm and 0.380.09cm, respectively. 4) Mean IVS/ LVPW in LGA and AGA were 1.09+0.12 and 1.040.17, respectively. There was no statistical significance between two groups in echocardiographic findings.
There is no relation between LGA and ASH in the neonate. According- ly, we may not need to perform echocardiography LGA routinely.
