- Published on: 20 February 2018Population-based study of cognitive outcomes in congenital heart defects: Novel Information about a not so uncommon entity
I read the article with interest and wish to congratulate the authors for their genuine work on a little known subject.
However there are certain points which require elaboration:
(a) It is likely that there are independent genetic factors that are responsible for a baby being born SGA and the same factors may be playing a role in affecting cognitive outcomes.These factors have not been addressed in the study.
(b) Cognitive outcome of a child is the result of certain internal and certain extraneous factors (eg environmental stimulation).The extraneous factors may confound the results of the above study.
(c) Open heart surgery per se may be detrimental to the cognitive development of a child .But there are certain factors such as Bypass time,duration of mechanical ventilation,exposure to hypotensive milieu,etc that need to be explored in order to get an indepth insight into the subject.
To summarize, the article is a praiseworthy effort into a novel field which opens up potentials of further avenues of research.Conflict of Interest:
None declared.
