About this study
Official title: The Role of Thiamine on Left Ventricular Structure and Function After Transcatheter Closure Through the Examination of MMP-9 Dan TIMP-1 in Children With Left-to-Right Shunt Congenital Heart Disease
Currently, research on the effect of thiamine administration during transcatheter closure on the structure and function of the left ventricle by examining levels of matrix metalloproteinase-9 and tissue inhibitor of metalloproteinase-1 in children with left to right shunt congenital heart disease has never been carried out in Indonesia, so it is necessary carried out this research. This research was carried out by administering 100 mg of thiamine once per day to patients post transcatheter closure for 28 days. The parameters assessed were MMP-9, TIMP-1, and echocardiography to assess the structure and function of the left ventricle in CHD patients with left to right shunt lesions.
Read the detailed description
Specifically the investigators want to study about :
- The differences in serum levels of matrix metalloproteinase-9 in patients with congenital heart disease with left to right shunt lesions after transcatheter closure who received thiamine and those who did not receive thiamine.
- The differences in serum tissue inhibitor of metalloproteinase-1 levels in patients with congenital heart disease with left to right shunt lesions after transcatheter closure who received thiamine and those who did not receive thiamine.
- The differences in left ventricular structure in patients with congenital heart disease with left to right shunt lesions after transcatheter closure who receive thiamine and those who do not receive thiamine.
- The differences in left ventricular function in patients with congenital heart disease with left to right shunt lesions after transcatheter closure who receive thiamine and those who do not receive thiamine.
- Conditions
- Congenital Heart Disease, Thiamine Deficiency, Patent Ductus Arteriosus, Ventricular Septal Defect, Atrial Septal Defect
- Being tested
- Thiamine
- Medical subject headings
- Heart Defects, Congenital, Thiamine Deficiency, Ductus Arteriosus, Patent, Heart Septal Defects, Ventricular, Heart Septal Defects, Atrial

What is being measured
The primary outcome is the main question the study is designed to answer.
Correlation between transcatheter closure and left ventricular structure change after thiamine treatment
The left ventricular structure of each participant is measured with echocardiography at the beginning and the end of the study and then the investigators calculate the left ventricular structure change (in percentage, %)
Measured: 1 day before transcather closure and 28 days after trancatheter closure
Secondary outcomes (3)
Correlation between transcatheter closure and left ventricular function change after thiamine treatment
The left ventricular function of each participant is measured with echocardiography at the beginning and the end of the study and then the investigators calculate the left ventricular function change (in percentage, %)
Measured: 1 day before transcather closure and 28 days after trancatheter closure
Correlation between transcatheter closure and serum matrix metalloproteinase-9 level change after thiamine treatment
The serum matrix metalloproteinase-9 level of each participant is measured at the beginning and the end of the study and then the investigators calculate the level change (in percentage, %)
Measured: 1 day before transcather closure and 28 days after trancatheter closure
Correlation between transcatheter closure and serum tissue inhibitor of metalloproteinase-1 level change after thiamine treatment
The serum tissue inhibitor of metalloproteinase-1 level of each participant is measured at the beginning and the end of the study and then the investigators calculate the level change (in percentage, %)
Measured: 1 day before transcather closure and 28 days after trancatheter closure

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Thiamine in people with Congenital Heart Disease and Thiamine Deficiency, run by Universitas Sumatera Utara at 1 site in Indonesia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Indonesia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Correlation between transcatheter closure and left ventricular structure change after thiamine treatment (time frame: 1 day before transcather closure and 28 days after trancatheter closure). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Mar 2026; AzTrials last refreshed its copy on 8 Nov 2026.
