  • All sexes
  • No healthy volunteers
  • Child, Adult

Study population: patients with pulmonary vein stenosis

Who may be able to join

  • Diagnosis can be based on clinical and radiographic grounds or at the time of biopsy or prior surgical procedures. The diagnosis must be consistent with multivessel pulmonary stenosis.
  • There must be evidence of severe pulmonary vein stenosis in at least two pulmonary veins.
  • Must give written informed consent according to institutional guidelines

Who cannot join

  • Mechanism of pulmonary venous obstruction due to obvious anatomic cause, such as extrinsic compression

About this study

Official title: Measurement of Angiogenic Related Growth Factors in Urine and Blood From Patients With Multivessel Pulmonary Vein Stenosis

Prospective, single center, descriptive study in 14 infants/children with multivessel pulmonary vein stenosis stratified for patients with or without underlying cardiac disease.

Group 1: Patients without additional structural heart disease and multivessel pulmonary vein stenosis.

Group 2: Patients with additional structural heart disease and multivessel pulmonary vein stenosis.

Read the detailed description

Patients identified at the time of presentation to their cardiologist will be asked to provide a urine sample for analysis. If blood is being drawn for other clinical tests, an extra vial of blood will be collected for measurement of bFGF, VEGF, angiopoietin 1\&2 and ephrin. At the time of blood draws, approximately 4 cc's of heparin blood will be obtained and processed as detailed below. Blood and/or urine samples will be coordinated through the data manager and will be performed only when blood is being obtained for other reasons. Initially, blood samples will be sent to Lab Control, spun down, and the plasma isolated. Plasma will be coded, then frozen at -200C in the research lab. Urine samples will be aliquoted into vials and stored at -20 until further analysis.

All patient information will be kept confidential. Individual results will not be provided to patients. Identifiers to patient information will be maintained. No identifying patient information will be used in publications that might result from these studies. Information to be collected by the data manager will include age, sex, date of diagnosis and interventions.

The specific aim is to assess angiogenic growth factor concentrations in urine and blood from patients with both congenital and acquired multivessel pulmonary vein stenosis.

Questions about this trial

What is this clinical trial studying?

An observational study of Multivessel Pulmonary Vein Stenosis, run by Boston Children's Hospital at 2 sites 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 3 inclusion and 1 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: stopped early, as of the sponsor's last update on 2 Aug 2012. Status can change between updates, so confirm with the study contact before making plans.

Are results available for this study?

The study was stopped early (reason given: Lack of funding). Results are not available in the source record.

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.

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 2 Aug 2012.
