Researchers at the Indiana University School of Medicine are seeking children and young adults to take part in a study to find out why children with single ventricle hearts develop heart failure.
This will be done by looking at how your body makes and processes energy and by comparing biological samples in children/young adults with heart failure (including those with a single ventricle or cardiomyopathy) to those who do not have any heart conditions.
Your participation will help researchers gain additional knowledge that could lead to improved ability to monitor the health of your heart more closely and to the development of new tests and treatments in the future. 


Who is Eligible
  • Ages 6 months - 25 years
  • Must be in overall good health with no medical conditions 
  • OR                                
  • Have a diagnosis of single ventricle heart or cardiomyopathy
What is Involved
One study visit at Riley Hospital for Children; the hour long visit would consist of: 
  • Provide a blood sample
  • Complete a FibroScan exam (a non-invasive ultrasound that takes measurements of your liver tissue and provides data regarding the status of your liver)
  • Provide a stool sample using a take-home kit (optional)
  • You will receive a $50 gift card for providing the blood sample and  completing the FibroScan
  • You will receive an additional $25 loaded to the gift card if you provide a stool sample. 
  • You will also receive the results of your FibroScan.
