Examining brain changes and cognitive function in adults with congenital heart disease

Exploring the Relationship Between Advanced Multimodal Brain MRI Phenotypes, Genes and Cognitive Outcome in Adults With CHD

Not applicable Interventional Boston Children's Hospital · NCT05258981

This study is trying to see how brain changes and genetics affect thinking skills in adults with a specific heart condition called d-TGA compared to people without the condition.

What this trial studies

This study investigates the relationship between brain MRI phenotypes and cognitive outcomes in adults with d-transposition of the great arteries (d-TGA). It aims to analyze sulcal patterns, structural connectivity, and functional connectivity using advanced MRI techniques to understand how these factors relate to executive function. Additionally, the study will explore how genetic variants related to neuroresilience and hypoxia response may influence these relationships. Participants will include individuals who were part of earlier studies at Boston Children's Hospital and age-matched controls.

Who should consider this trial

Good fit: Ideal candidates include adults with d-transposition of the great arteries who participated in previous studies at Boston Children's Hospital.

Not a fit: Patients with significant intellectual impairment or those unable to undergo MRI due to medical or psychological reasons may not benefit from this study.

Why it matters

Potential benefit: If successful, this research could enhance understanding of cognitive outcomes in adults with congenital heart disease, potentially leading to targeted interventions.

How similar studies have performed: While studies have explored cognitive outcomes in congenital heart disease, this specific approach combining MRI phenotypes and genetic factors is relatively novel.

Eligibility criteria

Inclusion Criteria:

* Persons who participated in the Boston circulatory arrest, pH and Hematocrit studies at Boston Childrens Hospital as children (n\~300).
* Normally-developed age- and sex-matched young adults who are able to provide informed consent to undergo the MRI portion of the study and limited neuropsychological evaluation (IQ assessment as well as neuropsychological tests for which normative references are not available).
