Infants, Children, Teens and Young Adults who have Tricuspid Atresia Needed for an Observational Research Study

Why are we doing this research?

Cincinnati Children’s is conducting a research study, sometimes known as a clinical study, to gather information about people with Tricuspid Atresia for a research registry.

We hope the information collected in the registry (a place where data and records are kept and made available for research) will help us to better understand the condition and help improve the lives of future patients. Specifically, we want to see if there are any differences in outcome after diagnosis in children who have different types of heart operations and find which treatment options are best. New treatment options include changes in the way corrective surgery is performed and other interventions that may influence long term care. This study may help your child’s physician decide which treatment is the best one for your child and other children in the future.

This registry is a collaboration of member institutions of the Congenital Heart Surgeons Society (CHSS).

What is the Congenital Heart Surgeons’ Society (CHSS)?

CHSS is a group of approximately 170 surgeons from 70 hospitals in the United States, Canada and South America collecting information on children with congenital heart disease. The members of this group all share a common interest in treatment and management of congenital heart malformations and are committed to research in this area.

Since children with congenital heart disease have many different and sometimes rare conditions, gathering information from many centers gives CHSS better information on how these children are doing. We also learn what factors and treatments have a better or worse result.

Where is the information collected for this registry kept?

Information collected is kept in a secure and confidential registry at the CHSS Data Center, which is at the Hospital for Sick Kids in Toronto, Ontario, Canada.

Who can participate?

Infants, children, teens and young adults who have Tricuspid Atresia with normally related great arteries and were born after October 1, 1998 may be eligible for participation.

What will happen in the study?

This is an observational study, and does not involve medicines. You (as a participant 18 and older) or your child will still take medicines normally needed and as prescribed by your doctor.

We would like to follow you/your child in this study throughout your/your child’s life so that we can evaluate long-term outcomes of Tricuspid Atresia. By agreeing to participate in this study, you are giving permission for the study doctors to contact you and/or your child as mentioned below. If you are a parent, once your child is old enough to understand and participate in the consent process, we will ask if he/she is willing to continue in the study.

If you/your child participate in this study, your/your child’s medical chart will be reviewed for certain information. Information regarding your/your child’s name, date of birth, contact information, surgery, and hospitalization will be sent to the CHSS Data Center. Information such as your/your child’s diagnosis, anatomy, surgical procedures, and follow-up visits will be entered into a password-protected computer database. All of this information will be kept confidential.

Once this information is collected and sent to CHSS, a unique study identification number will be created for you/your child so that personal health information will not be used directly in any further analysis or correspondence.

A specially trained staff member from the CHSS Data Center will call you to welcome you/your child into the study. Then, every year, a staff member from CHSS or Sick Kids will contact you, by phone and/or mail, to ask how you/your child are doing and ask that you fill out a short survey. The survey, which takes 10 to 15 minutes, will have questions about your/your child’s health, quality of life, activity level and medical care.

Information from your/your child’s medical records will also be collected each year and sent to the CHSS Data Center.
Your/your child’s information will be analyzed together with information from other people with the same heart defect from collaborating centers. It will be used to determine the impact of patient factors and different treatments on results and to examine the overall health status of children with Tricuspid Atresia.

You, as a parent/guardian or participant, will be given a consent form that thoroughly explains all the details of the study. A member of the study staff will review the consent form with you and will be sure that all your questions are answered.

What are the good things that can happen from this research?

You/your child may not receive a direct medical benefit from taking part in this study. However, the information collected by this study may contribute to the care of children in the future who have the same heart condition and may also improve the future management of your/your child’s condition.

What are the bad things that can happen from this research?

There are no medical harms, discomforts, or inconveniences associated with taking part in this study. If you agree for to participate, or to have your child to participate in the study, your/your child’s diagnostic testing, surgery, or other interventions will not be changed in any way.

All records associated with your/your child’s participation will be kept strictly confidential within the CHSS Data Center registry and at Cincinnati Children’s. Personal health information will not be released to any outside individuals or used in any publication. It is not likely, but possible, that confidentiality may be lost in this study. We will take every reasonable precaution to avoid this from happening.

All possible risks will be discussed with you and/or your child if you are interested in learning more about the study.

Will you/your child be paid to be in this research study?

Participants will not receive pay for taking part in this study.
