Hypertrophic Myopathy in Children
The purpose of this study is to identify the patients seen in our practice who are seen with Hypertrophic Myopathy diagnosis in order to better understand the presenting characteristics of their disease, the diagnostic testing to determine the diagnosis, the methods used to follow the disease progression and management practices used in caring for these patients. The objectives of this data review will be an analysis to determine if there is a methodology that will foster improved diagnostic speed and accuracy, and determine the best management practices based on outcomes in these patients.

|Official Title:||Retrospective Review of Hypertrophic Myopathy in Children|
|Study Start Date:||January 1996|
The charts of children followed at Sibley Heart Center of Children's Healthcare of Atlanta will be identified using the Mysis system and screening for the appropriate ICD-9 codes for the types of Hypertrophic Myopathy. These codes include: 425.1, 425.4, 425.7, 425.8, and 425.9. Screening will also be done for known anomalies that are associated with hypertrophic myopathy as seen in some syndromes and metabolic disorders.

A generalized linear model will be performed. Significance will be defined at P≤ 0.05.
Interim monitoring of accumulated data will be performed. One interim analysis will be performed after 3 months of accrual with additional analyses being performed at the end of data collection.
Demographic data will be summarized for all subjects. For each patient summary statistics will include the mean, standard deviation, frequency distribution, minimum, maximum and range.
