Myocardial Perfusion and Scarring in Congenital Heart Disease

Stopped: PI is leaving NHLBI, sample size is too small.

Plain-language summary

Background: \- People with congenital heart disease may develop heart failure earlier that those who do not have the disease. One theory to explain this is that the heart s own blood supply may be different in people with congenital heart disease. Problems with this blood supply can severely damage the heart. This damage can be studied with a heart imaging test called a cardiac magnetic resonance imaging (MRI) scan. Researchers want to use this type of scan to look at the blood supply to the heart in people with congenital heart disease. Objectives: \- To learn more about the blood supply to the heart in people with congenital heart disease. Eligibility: \- Individuals at least 18 years of age who have heart defects caused by congenital heart disease. Design: * Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. * Participants will have a cardiac MRI scan to look at the blood flow to the heart. * Participants will also have a heart stress test to measure heart function during exercise. * Other imaging studies of the heart may be performed to collect more information on heart function.

* INCLUSION CRITERIA: Inclusion Criteria for All Arms of the Protocol: * 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: Exclusion Criteria for All Arms of the Protocol: * Subjects with a contraindication to 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 * Cochlear implant * Ocular foreign body (e.g. metal shavings) * Implanted Insulin pump * Metal shrapnel or bullet * Severe heart damage that makes it difficult to breathe while lying flat * Pregnant women (Women of childbearing potential who are uncertain as to whether they are pregnant will be required to have a screening urine or blood pregnancy test) * Subjects with active symptoms of myocardial ischemia occurring despite maximally tolerated doses of oral antianginal therapy and intravenous nitroglycerin Furthermore, the following subject groups will be excluded from studies involving the administration of MRI contrast agents: * lactating women unless they are willing to discard breast milk for 24 hours after receiving gadolinium * renal disease (estimated glomerular filtration rate \[eGFR\] \< 30 ml/min/1.73 m2 body surface area) The eGFR will be used to estimate renal fu…

What they're measuring

Hypothesize that myocardial ischemia, as detectable by quantitative stress perfusion MRI, will predict systolic and diastolic dysfunction in subjects with single ventricle physiology and systemic right ventricles.
