Optimal normative pediatric cardiac structure dimensions for clinical use.

Cardiac structure size influences surgical decision making in pediatric cardiac surgery. Lack of universally adopted normative cardiac structure dimensions may confound decision making. A review of the relevant literature contained in 2 large databases was performed with a view to determine the optimal normative cardiac structure dimensions for clinical use. The current article initially discusses technical issues related to cardiac structure measurement and measurement normalization. It then describes the literature search strategy and examines the quality of published data in subjects below 19 years of age. The optimal normative dimension data set is then recommended.
