Assessment of bone mineral density in children with congenital cyanotic heart disease

Cyanotic CHD is one of many disorders in paediatrics that influence the health of children in different clinical aspects. One of the fundamental aspects that may be affected is bone mineral density. The aim of our study is to assess bone mineral density in children with congenital cyanotic heart disease of different anatomical diagnoses. Cross-sectional, observational study included 39 patients (20 males) with congenital cyanotic heart disease of different anatomical diagnoses following with the cardiology clinic in Mansoura University children's hospital. All patients were subjected to anthropometric measures, oxygen saturation assessment, and lumber bone mineral density using dual-energy X-ray absorptiometry. Six patients (15.4%) out of the 39 included patients showed bone mineral density reduction, 13 patients (33.3%) showed bone mineral density with Z-score between -1 and -2, while 20 patients (51.3%) showed bone mineral density with Z-score more than -1. Low bone mineral density can be found in children with cyanotic CHD, making it important to consider bone mineral density assessment and early treatment if needed to avoid further complications.
