Trial summary

Introduction: The presence of pulmonary hypertension (PH) in atrial septal defect (ASD) poses a clinical challenge on whether or not to close the defect. Closing the defect increases the risk of low cardiac output syndrome (LCOS), while leaving the defect open may eventually lead to irreparable shunt reversal… Read more about this study

About this study

Official title: Improvement In Left Ventricular Diameter After Closure Of Atrial Septal Defect With Fenestrated Patch: A Cross-sectional Study

Introduction: The presence of pulmonary hypertension (PH) in atrial septal defect (ASD) poses a clinical challenge on whether or not to close the defect. Closing the defect increases the risk of low cardiac output syndrome (LCOS), while leaving the defect open may eventually lead to irreparable shunt reversal, hypoxemia, and death. The implementation of a fenestrated patch may halt LCOS while adding volume to the left heart.

Methods: this is an analytical observational study involving patients with ostium secundum defect with PH who were operated on in Dr. Soetomo Hospital between January 2017 and October 2021. The aim of this study is to evaluate the improvement in left ventricular size during both systole and diastole.

Read the detailed description

Atrial septal defect (ASD) is one of the most common congenital heart diseases. It is typically characterized by a left-to-right shunt which results in volume overload of the right ventricle and overcirculation of the pulmonary vascularization (le Gloan et al., 2018). This may further result in arrhythmia, right ventricular dysfunction, and pulmonary hypertension (PH). Pulmonary hypertension is caused by endothelial dysfunction, remodelling of the pulmonary vascularization, which increases pulmonary vascular resistance, and eventually causes shunt reversal into right-to-left (Eisenmenger's syndrome). At this point, closure of the defect is contraindicated.

Small LV, although less extensively studied than dilated LV, also implies impaired LV function. Small LV means less tolerance to volume overload, which in turn impairs cardiac output and presents higher risk of heart failure and mortality (Saito et al., 2021).

ASD closure in cases with severe pulmonary hypertension (PH) presents a clinical challenge. Complete closure may cause pulmonary hypertensive crisis and low cardiac output syndrome; however, if left untreated, the disease progresses, the pulmonary vascular resistance increases, which may also lead to Eisenmenger's syndrome and shunt reversal. Today, this condition is treated with fenestrated closure, either with patch or fenestrated septal occluder. The fenestration is hypothesized to provide protective effect against pulmonary hypertensive crisis because it allows blood to flow from right to left heart. The added volume into the left heart is then, hypothesized, to provide volume training for the left heart, mainly in the case of small LV. Therefore, this study aims to evaluate the effect of fenestrated closure compared to non- fenestrated closure to the left ventricular size at systole and diastole.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ASD closure with fenestrated/non-fenestrated patchProcedure or surgery

    A PTFE patch is used to surgically close the interatrial defect. If closure with fenestrated patch is deemed necessary, a small opening is created on the patch

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Improvement in left ventricular diameter during systole and diastole

    The change in left ventricular diameter during both systole and diastole is measured preoperatively and postoperatively

Questions about this trial

What is this clinical trial studying?

An observational study of Atrial Septal Defect, run by Dr. Soetomo General Hospital 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 2 inclusion and 2 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 18 Nov 2023. 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.

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?

Improvement in left ventricular diameter during systole and diastole (time frame: January 2017 - October 2021). 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 18 Nov 2023.
