Heart MRI stress test for Fontan circulation
Part of Genetic & congenital, Heart & circulation clinical trials.
This study uses a special heart MRI with a medicine that stresses the heart (like exercise) to look at blood flow in people who have had the Fontan surgery. The goal is to better understand how the heart works after this surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have had the Fontan operation (also called total cavo-pulmonary connection) for a heart condition.
- You feel generally well with no more than slight limits on physical activity (NYHA class I or II).
- You are 18 years or older.
- You do not have a pacemaker or implantable defibrillator (ICD).
- You do not have advanced kidney failure (GFR less than 30).
- You do not have atrial fibrillation, and you are not pregnant (if applicable).

This study uses MRI (a scanning test) to develop new ways to measure heart function in both healthy volunteers and people with suspected or known heart disease. It may help researchers create better heart tests that could improve future diagnosis and monitoring.
This trial looks at how tiny blood vessels in the heart affect improvement in heart pumping strength for people with heart failure. It tests whether a special procedure during heart catheterization can predict recovery.
This study compares two heart imaging scans to see if a newer CT scan works as well as an MRI for checking blood flow and heart tissue in people having a heart valve replacement. It may help improve care for patients with aortic stenosis.
This study uses a special stress heart MRI to measure blood flow and find blockages in the arteries that supply your heart. It is for people with chest pain or abnormal EKG results who have risk factors for heart disease, to help doctors diagnose and treat coronary artery disease more accurately.
This study tests a new way to diagnose small blood vessel disease in the heart using an MRI scan during a stress test. It is for people who are already participating in a larger heart imaging study and are scheduled for a catheter procedure.
This study tests a new way to measure blood flow in the heart using an MRI scan. It may help doctors better diagnose chest pain and decide on treatment.
