Overview
Brief Summary
This is a study of the perfusion of the myocardium in adults with specific forms of repaired congenital heart disease using established cardiac MRI techniques and correlating perfusion with clinical outcomes.
Detailed Description
This is a study of the perfusion of the myocardium in adults with specific forms of repaired congenital heart disease using established cardiac MRI techniques and correlating perfusion with clinical outcomes. The investigators objectives are to examine myocardial perfusion both during stress and at rest in adults with repaired or palliated congenital heart disease as well as quantify ventricular function, regional myocardial strain and evidence of myocardial fibrosis with quantitative measures of myocardial perfusion. The specific aim of this study is to understand whether clinical subendocardial perfusion defects contribute to the late decompensation of adult subjects that have single ventricle physiology and adult subjects that have a systemic right ventricle.

Eligibility Criteria
Inclusion Criteria
- •Subjects 18 years of age or older
- •All defects that have a right ventricle that supports the systemic circulation
- •All defects with a functional single ventricle
- •Written informed consent
Exclusion Criteria
- •Subjects with a contraindication to magnetic resonance imaging (MRI) scanning will be excluded. These contraindications include subjects with the following devices:
- •Central nervous system aneurysm clips
- •Implanted neural stimulator
- •Implanted cardiac pacemaker or defibrillator
