Official title
Myocardial Ultrasonic Tissue Characterization in Patients With a Genetic Predisposition for the Development of Hypertrophic Cardiomyopathy
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The human heart is divided into four chambers. One of the four chambers, the left ventricle, is the chamber mainly responsible for pumping blood out of the heart into the circulation. Hypertrophic cardiomyopathy is a genetically inherited disease causing an abnormal thickening of heart muscle, especially the muscle making up the left ventricle. When the left ventricle becomes abnormally large, it is called left ventricular hypertrophy (LVH). Patients with HCM can be born with an enlarged left ventricle or they may develop the condition in childhood or adolescence, usually during the time when the body is rapidly growing. However, not all patients with the abnormal genes linked to HCM have the characteristic LVH. Currently, it is impossible to tell if a patient with the genes for HCM will develop LVH. A recently developed ultrasound tool called an integrated backscatter analysis (IBS), may allow researchers to determine those children who may later develop HCM and LVH. In order to test this, researchers plan to use IBS to study normal children with relatives diagnosed with HCM. This study will compare the results of IBS done on normal children with relatives diagnosed with HCM , normal children, and children with evidence enlarged heart muscle (HCM).
