AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for children and young people having heart surgery for a heart defect. Blood tests before and after surgery check a marker called sST2 for signs of heart failure.

Age
Younger than 18 years (maximum age 18 years).
Sex
All sexes can join.
Disease stage
Planned surgery with cardiopulmonary bypass (heart-lung machine) for a heart reason, such as congenital heart disease.
Biomarker or test result
The trial measures the blood marker sST2; having a certain level is not required to join.

Main reasons for not taking part

  • Known genetic conditions that limit life
  • Syndrome patients scheduled, or highly likely, to have surgery on more than one organ
  • Body weight under 2.5 kg (6 lb) at the time of surgery
  • Taking part in an interventional study already
  • Not able to understand and sign a consent form in German (child or representative)

About the trial

What the trial wants to find out

Patients younger than 18 scheduled for congenital heart surgery will be assessed during and post-operatively as well as at the first follow-up after 9-12 month for the novel biomarker sST2. We will assess the marker independently and in evaluation with other blood biomarkers to evaluate sings of heart failure. Compared to established biomarkers, sST2 promises thereby to be less variable to factors like age or acute kidney injury, rendering it potentially more reliable in the field of congenital cardiac surgery.

The group in the trial

  • Patients planned for congenital cardiac surgery
