To participate in the research that is changing the future for individuals with HLHS, contact our program by emailing us at HLHS@mayo.edu.
Genetics: The goal of this study is to identify abnormal genes that may cause the underdevelopment of the left ventricle. We analyze the DNA of the HLHS patient, their immediate family members, and sometimes extended family members. This is done by collecting a blood or saliva sample from each participating family member.
Imaging: This study uses echocardiogram and MRI images to assess the function of the right ventricle. An HLHS patient has an echocardiogram and/or MRI, X-ray, and clinical exam performed by a pediatric cardiologist and an echocardiogram is done on the biological parents and siblings. All of the imaging findings are made available to you and the HLHS patient’s home cardiologist.
Regenerative Strategies: Participation in this study involves collecting a small piece of discarded skin tissue when there is a clinically planned surgery, or from a skin punch biopsy. The goal is to "reprogram" the skin cells into cardiac tissue. We are collecting tissue from the patient with HLHS, both biological parents, and eligible siblings (age dependent).
