Heart Institute Biobank & Registry for Adult Congenital Heart Disease and Related Disorders
(HIBR-ACHD)
What this study is about
A repository of biospecimens and detailed phenotypic information collected longitudinally from adults with congenital heart disease and related conditions, with an aim to facilitate future research on biologic mechanisms of underlying disease, compensation and deterioration; biologic correlates of patient experience and functional status; associations between clinical characteristics and various biomarkers; and predictors of clinical outcomes.
View original scientific description

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Any person ≥ 16 years-old suspected of having or diagnosed with congenital heart disease (CHD), other cardiovascular disease (CVD), pulmonary hypertension, connective tissue disease, or genetic syndrome/diagnosis.
- Additionally, a cohort (Control group A) of control subjects will be enrolled, again ≥16 years-old, self-reported non-smokers without a known history of diabetes mellitus, myocardial infarction, stroke, heart failure, or chronic kidney disease. These controls will be either:
- A family member or other person accompanying a patient to a clinical encounter; or,
- A volunteer recruited via an advertisement; or,
- Another person who volunteers to enroll in HIBR-ACHD.
- A cohort (Control group B) of comparison subjects who do not have CHD, but have a diagnosis of heart failure or pulmonary hypertension.
Exclusion criteria
- Unable to provide informed consent/assent personally or via a legal guardian.
- Considered unsafe to collect the biospecimen determined by either a clinical provider or an HIBR-ACHD investigator.
- Overnight hospitalization for non-obstetric reason with discharge in the prior 30 days.
Where
- Cincinnati, Ohio
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
