Brief Summary
The goal of this observational study is to investigate the ability of the SpectroCor Tissue Oxygenation Monitor and its accessory SpectroCor Sensor to observe and monitor changes in cardiac oxygen availability in pediatric patients during open-heart surgery. Patients of less than 18 years old who, and whose guardian(s), when applicable according to national legislation, have signed the informed consent, can participate in the study. The primary hypothesis is that the SpectroCor Tissue Oxygenation Monitor and its accessory SpectroCor Sensor can detect myocardial oxygen availability in pediatric open-heart surgery patients. It is expected that the detected tissue oxygenation timely correlates with procedures affecting myocardial perfusion and other clinical parameters during the operation. The secondary hypothesis is that the SpectroCor Tissue Oxygenation Monitor and its accessory, the SpectroCor Sensor, are safe to use, and their usability is acceptable. No comparison group is included in the study. The devices are used by the study investigators during open-heart surgery to collect myocardial tissue spectrometer data from the pediatric population to validate and potentially further develop the monitor and its accessory, the sterile sensor. The follow-up period for each participant ends with discharge from the hospital. No data (such as questionnaires) are obtained directly from the study participants.

Data Sharing
- IPD Sharing
- Will not share
Individual participant data will not be shared. The investigation enrols minors undergoing congenital cardiac surgery at a single centre, a rare and heterogeneous population in which the small sample size and detailed intraoperative and perioperative data create a substantive risk of re-identification. Participant consent and the approved Clinical Investigation Plan do not cover secondary sharing of individual-level data, and the sponsor's obligations under Regulation (EU) 2016/679 (GDPR) preclude onward transfer without a valid legal basis. Aggregate results will be published in accordance with the publication policy and made publicly available in EUDAMED, and the clinical investigation report will be submitted to the competent authority within one year of the end of the investigation.
