What this trial studies

This study investigates the effects of thiamine administration on children with left-to-right shunt congenital heart disease following transcatheter closure. Participants will receive 100 mg of thiamine daily for 28 days, and researchers will assess changes in serum levels of matrix metalloproteinase-9 and tissue inhibitor of metalloproteinase-1, as well as evaluate left ventricular structure and function through echocardiography. The goal is to determine if thiamine can improve heart function and structure in these patients.

Who should consider this trial

Good fit: Ideal candidates are children aged 6 months to 18 years diagnosed with left-to-right shunt lesions and heart failure.

Not a fit: Patients with acute infections, other heart defects requiring surgery, or chronic diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could enhance heart function and structural outcomes in children with congenital heart disease.

How similar studies have performed: This approach is novel and has not been previously tested in Indonesia, though similar studies may exist elsewhere.
