What this trial studies

This observational study aims to evaluate the effectiveness of rivaroxaban in resolving intracardiac thrombi in pediatric patients under 16 years old. Participants who are already receiving rivaroxaban as part of their medical care will be monitored over a 3-month period with monthly visits to assess treatment progress and bleeding risks. The study will involve initial treatment with enoxaparin for 7 days, followed by rivaroxaban, with imaging studies conducted before and after treatment to confirm thrombus resolution. The primary goal is to determine if rivaroxaban can effectively resolve the thrombosis within the treatment timeframe.

Who should consider this trial

Good fit: Ideal candidates are pediatric patients under 16 years old diagnosed with intracardiac thrombosis confirmed by imaging.

Not a fit: Patients with major bleeding events or abnormal coagulation tests prior to enrollment may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a safer and effective option for resolving heart clots in pediatric patients.

How similar studies have performed: While rivaroxaban has been studied in adults, this specific application in pediatric patients is novel and has not been extensively tested.
