ABSTRACT

The objective of this paper is to determine the frequency and outcome of asymmetrical septal hypertrophy (ASH) in large-for-gestational-age infants (LGA) born to diabetic (DM) and nondiabetic mothers (NDM), and to establish the relationship between ASH and maternal diabetes control. A comparative study was design to assess ASH in infants born to DM and NDM. The study was conducted in the Departments of Neonatology and Pediatric Cardiology of the ``Hospital de Gineco-Pediatria 48'', Instituto Mexicano del Seguro Social from January to December 1997. Eighty-five full-term infants of DM (group A) and 85 LGA infants of NDM (group B) were included. As a control group (group C), we studied 85 healthy, full-term infants. In all cases a Doppler echocardiogram was obtained in the first 48 h after birth, and for the ASH infants, at 2 and 4 months. Chest X ray, electrocardiogram, and laboratory tests were performed as complementary studies. ASH was present in 38.8% of LGA infants of DM and in 7.1% of NDM. The difference was significant (p < 0.01). Interventricular septum (IVS) and IVS/ posterior wall of left ventricle ratio were significantly different between groups A and B with C. There was no correlation between Hb A1 level and the presence of ASH in group A. ASH is a common finding in infants of DM. We could not find a relationship between the degree of metabolic control during pregnancy and the incidence and severity of ASH.
