ClinicalTrials.gov Identifier: NCT00571233
Recruitment Status : Completed

Brief Summary:
The purpose of this study is to determine if children with heart disease where there is only one pumping chamber("ventricle") have proteins (biomarkers") in the blood that can be used to monitor the function of their heart.

Condition or disease
Tricuspid Atresia Hypoplastic Left Heart Syndrome Unbalanced AV Canal

Detailed Description:
We will investigate whether levels of blood proteins in children with well-functioning hearts with one ("single") ventricle are similar to levels of these blood proteins in children with two ventricles. For children with hearts with a single ventricle, we will examine blood proteins at various levels of heart function. To assess blood protein levels, we will collect small (6 mL) samples of blood. Heart function will be determined by existing clinical scoring systems. Enrolled patients will receive an echocardiogram, which is a dynamic ultrasound picture of the beating heart.

Study Type : Observational
Actual Enrollment : 71 participants
Observational Model: Case Control
Time Perspective: Cross-Sectional
Official Title: Identification of Biomarkers for Heart Failure in Children With Single Ventricle Physiology
Study Start Date : February 2007
Primary Completion Date : December 2011
Study Completion Date : January 2015

Group one consists of children 1 month - 6 years old who have structurally normal hearts, no heart failure, and a patent ductus arteriosus (PDA).
Group two consists of children 1 month - 6 years old who have single ventricle physiology. Children with and without heart failure may participate.

Primary Outcome Measures :
  1. Heart failure, as assessed by clinical scoring systems. [ Time Frame: Cross-sectional. We will obtain blood samples and assess for heart failure (function) concurrently when patients present to the Pediatric Heart Center ]

Secondary Outcome Measures :
  1. Echocardiographic indices. [ Time Frame: Cross-sectional ]

Biospecimen Retention:   Samples With DNA

Ages Eligible for Study:   1 Month to 6 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients presenting to the UCSF Pediatric Heart Center.

Inclusion Criteria:

  • Children with a structurally normal heart and a patent ductus arteriosus.
  • Children with single ventricle physiology.

Exclusion Criteria:

  • Children must not have chromosomal abnormalities. Small deletions, such as that which produces DiGeorge syndrome, are permissible.
  • Children with acute intercurrent non-cardiac inflammatory illness (such as post-operative wound infection) are ineligible, as such conditions may cause elevated blood levels of the proteins under study.
