Genetic analysis of congenital heart defects

Genetics of Ventriculo-arterial Discordance: Towards a PRECIsion Medicine in PEDiatric Cardiology

NA · Nantes University Hospital · NCT05330338

What this trial studies

This study investigates the genetic factors associated with ventriculo-arterial discordance in patients with congenital heart defects. It involves a multicentric, prospective design across 16 centers in France, aiming to recruit up to 900 individuals, including family trios of patients with specific heart conditions. Participants will undergo whole genome sequencing to identify potential genetic links to their conditions. The study is planned to last 22 years, with a recruitment period of 24 months and a follow-up time of 20 years for each patient.

Who should consider this trial

Good fit: Ideal candidates include patients with transposition of the great arteries or congenitally corrected transposition with healthy parents and no family history of congenital heart disease.

Not a fit: Patients with additional heart malformations or syndromes, or those under guardianship, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of congenital heart defects, potentially guiding personalized treatment strategies.

How similar studies have performed: Other studies have shown promise in genetic analyses of congenital heart defects, suggesting that this approach may yield valuable insights.
