Use of Magnetic Field Mapping in the Evaluation of Patients With Hypertrophic Heart Disease (Thick Heart Muscle)

Withdrawn before enrolling

Conditions studied: Hypertrophic Cardiomyopathy

In brief

The purpose of this research study is to further establish the diagnostic use of magnetocardiography (MCG) in patients with hypertrophic cardiomyopathy (HCM). The use of MCG has not been extensively studied in these patients. This pilot study will serve to further characterize abnormalities found on MCG in comparison to patients without hypertrophic cardiomyopathy. Additionally, the study will be used to understand whether MCG has any additional diagnostic utility in offering clinicians insight on the patient's disease state, thereby aiding in the development of treatment plans. This research study is designed to test the effectiveness of the investigational use of magnetocardiography in patients with hypertrophic cardiomyopathy. The device itself has been approved by the U.S Food and Drug Administration (FDA).

Who can join

Age: 16 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Any patient that is hemodynamically stable and is identified to have hypertrophic cardiomyopathy based on prior symptoms, 2D ECHO findings, genetic testing, and/or ECG voltage criteria.
• Patients that have signed informed consent after understanding the risks and benefits of participation. Individual age 16-17 with the consent and approval of a parent and /or legal guardian.

You may not qualify if…

• Patients with prior history of myocardial infarction, CAD demonstrated by stress test or angiogram, and/or CABG will be excluded from this study.
• Any patient that has undergone invasive treatment at the time of enrollment including procedures such as myomectomy and/or septal ablation. However, already enrolled subjects who have these procedures post-enrollment into the study will be eligible for future scans.
• Patients encountering any significant symptoms, chest pain, or who are hemodynamically unstable.
• Any patient with an ICD or pacemaker.
• Patients who are underage and do not have the consent of a parent and/or legal guardian.
