Various means have been proposed to account for body size in various cardiac measurements such as ventricular size or aortic diameter. The z-score, a well established process used in pediatrics to account for changes with somatic growth, reflects the position of a measurement, expressed in standard deviations, relative to the mean of the population distribution. Yet the z-score method has not been adapted in adult cardiology practices. In adult congenital heart disease, what is the potential role of z-scores for anthropomorphic indexing? We present arguments for and against the use of z-score nomograms as an indexing method in adults with congenital heart disease.
