LE ROY, Catalina; LARIOS, Guillermo; CLAVERIA, Cristian  and  SPRINGMULLER, Daniel. Short stature among children undergoing cardiac surgery for congenital heart defects. Arch. argent. pediatr. [online]. 2019, vol.117, n.3, pp.e211-e217. ISSN 0325-0075.

Introduction. Children with congenital heart diseases (CHDs) suffer from malnutrition because of nutritional deficiencies, being short stature the possible long-term consequence. Objective. To describe the presence of short stature among children undergoing cardiac surgery for CHDs. Population and methods. Retrospective study. Children undergoing cardiac surgery with cardiopulmonary bypass pump between 2009 and 2013 were included. Preterm infants, carriers of genetic syndromes or other disease with nutritional compromise were excluded. Demographic data, type of CHD, admission surgery and anthropometric assessment using the WHO standards were studied. Short stature was defined as lenght/height for age Z score < -2 standard deviations, by sex. Results. A total of 640 children were studied; 361 (56.4 %) were boys; median age: 8 months (IQR: 1.9; 34.6); 66 children underwent > 1 surgery; 27 of them (40.9 %) had hypoplasia of the left ventricle. There were 358 (55.9 %) infants with cyanotic CHDs, 196 (30.6 %) with univentricular physiology. The median HAZ was -0.9 (IQR: -1.9; -0.1); 135 (21.1 %) had a short stature, 11 % of newborn infants and 24.1 % of older than one month old. A higher frequency of short stature was observed in 4 out of 6 children who underwent complete repair of the atrioventricular canal, in 15 out of 39 infants with repair of tetralogy of Fallot, in 8 out of 25 infants with hypoplasia of the left ventricle subjected to Glenn procedure, and in 34 out of 103 with closure of the ventricular septal defect. No association or statistically significant difference was found between short stature and cyanosis or univentricular physiology. Conclusions. There is a high frequency of short stature among children with CHDs, with differences according to the type of CHD and cardiac surgery performed.
