A study of the clinical course of edema in nephritis, recently published by Aldrich,1 prompted me to attempt a similar study of the edema associated with heart disease in children. The underlying thought in both these observations has not been to advance any new theories regarding the cause and nature of edema, but rather to add precise clinical data to the knowledge of this interesting problem.
During the past five years, I have had the opportunity of observing a large number of children with heart disease, and as these children have gone on to recovery, chronic invalidism or death, I have been impressed with the wide variations in the symptoms and signs encountered.
