Objective: Congenital heart disease has an overall incidence of 8 per 1000 live births. It can be grouped into acyanotic congenital heart diseases (without a shunt or with a left to right shunt) and cyanotic congenital heart disease (with a right to left shunt). Cyanotic congenital heart diseases are those inborn lesions of the heart and great vessels in which there is shunting of blood from right side of the heart to the left side with the result that de-oxygenated blood enters the systemic circulation, thereby decreasing its oxygen saturation and causing cyanosis. The commonest of these diseases is Tetralogy of Fallot's. Only a few of these diseases are compatible with life beyond 12 years of age. Methods: The present study was carried out in the department of Pediatrics, Mahatma Gandhi Memorial Medical College, Indore from January 2012 to July 2013 (duration of study was one and half years). During this period thirty children with congenital cyanotic heart disease between 6 months to 5 years of age were included in this study. Blood parameters assessed were Hemoglobin (Hb gm%), Mean Corpuscular Volume (MCV) fl and Ferritin levels. Results: The mean hemoglobin in cyanotic heart disease cases was 13.39 gm/dl with a S.D. of 2.38. In the control group the mean hemoglobin was 9.57 gm/dl with a S.D. of 1.29. Mean MCV in cyanotic heart disease cases was 71.47 fl with S.D. of 9.28 and in controls it was 78.41 fl with a S.D. of 5.87. Mean Ferritin in cases was 41.63 ng/ml with S.D. of 35.04 and in controls it was 78.75 ng/ml with S.D. of 51.40. P value was 0.001 indicating a statistically significant decreased ferritin in cases. Conclusion: Iron deficiency anemia was present in 56.6% of the cases on basis of MCV. The high iron requirements of cyanotic heart disease cases due to increased erythrocytosis induces iron deficiency anemia.There was statistically significant difference in Hb and MCV values between cases and controls. The ferritin level was statistically significantly lower between cases and controls suggesting iron deficient state in CCHD patients. Iron therapy in iron deficient CCHD (based on hematological and iron indices) patients might improve clinical outcome in these patients.
