Trial summary

This study is a prospective, randomized study of patients with single ventricle heart disease who are to undergo superior cavo-pulmonary anastomosis, or "Glenn" operation. Such patients have historically undergone cardiac catheterization to ensure suitability for the procedure. Read more about this study

About this study

Official title: Clinical Trial of Cardiac Magnetic Resonance Imaging in Routine Evaluation Prior to Superior Cavo-Pulmonary Anastomosis

This study is a prospective, randomized study of patients with single ventricle heart disease who are to undergo superior cavo-pulmonary anastomosis, or "Glenn" operation. Such patients have historically undergone cardiac catheterization to ensure suitability for the procedure. Cardiac magnetic resonance imaging (cardiac MRI) is a newer technology that provides excellent anatomic and functional imaging of the heart. This study is designed to demonstrate our hypothesis that cardiac magnetic resonance imaging will provide comparable information to catheterization, with less side effects.

Read the detailed description

This is a prospective, randomized study of patients with single ventricle congenital heart disease presenting for superior cavo-pulmonary anastomosis, or "Glenn" operation. Such patients in the past have routinely undergone pre-operative invasive cardiac catheterization to assess anatomic and hemodynamic suitability for this procedure. Recent retrospective reviews, including our own (J Thorac Cardiovasc Surg 2003: July;126(1):272-81) have suggested that such catheterization may not benefit many patients, and that non-invasive assessment may allow adequate evaluation while avoiding many (typically minor) complications seen with cardiac catheterization in this high risk group of infants. Cardiac MRI is a non-invasive imaging modality that can deliver superior anatomic information (such as vascular and intracardiac anatomy) as well as functional data (ventricular volumes and ejection fraction), and may be a safe alternative to catheterization in such patients. In this study, patients undergo screening echocardiogram prior to enrollment in the study to assess degree of risk for the operation (such as pulmonary vein obstruction, a clear risk factor for poor outcome) or for demonstrated need for catheterization intervention (such as aortic arch obstruction requiring balloon dilation); patients with low risk echocardiograms whose parents grant informed consent for the study are then randomized in a prospective fashion to cardiac MRI or cardiac catheterization. The findings of each study are then reviewed by the subject's cardiologist and cardiac surgeon; patients in whom further pre-operative information may cross over to another study if deemed necessary (such as catheterization in patients in whom an unsuspected finding is noted, or cardiac MRI in patients in whom further functional data may be desired). Patients are followed for details of the hospital stay (including hospital length of stay, complications, hospital charges) for the pre-operative testing, as well as operative and post-operative outcomes (new/missed diagnoses, hospital stay, operative and post-operative complications, achievement of a clinical definition of a "good" outcome from the Glenn operation).

Questions about this trial

What is this clinical trial studying?

A study testing Diagnostic cardiac MRI and Cardiac catheterization in people with Congenital Heart Defects, run by Boston Children's Hospital at 1 site in United States.

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 1 inclusion and 4 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 31 Jan 2008. 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 United States. 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?

Toxicity profile for each group (time frame: 3 Months Post-Glenn operation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00112424, which also lists 2 linked publications.

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 31 Jan 2008.
