What this trial studies

This observational study aims to collect and analyze data from children with congenital heart disease who have undergone the Fontan procedure and are prescribed rivaroxaban. The study will focus on understanding how well rivaroxaban works in preventing blood clots and assessing its safety profile in this specific pediatric population. By monitoring these patients, researchers hope to gather insights into the risks and benefits of using rivaroxaban compared to other treatments like aspirin. The findings could help inform future treatment guidelines for children with congenital heart disease.

Who should consider this trial

Good fit: Ideal candidates for this study are children under 18 years old diagnosed with congenital heart disease who have undergone the Fontan procedure and are being treated with rivaroxaban.

Not a fit: Patients who have contraindications to rivaroxaban or have previously been treated with it may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable information on the safe use of rivaroxaban in preventing blood clots in children after heart surgery.

How similar studies have performed: Previous studies have suggested that rivaroxaban may have a comparable safety profile to aspirin in children with congenital heart disease, indicating potential for success in this observational approach.
