In the article by Abdelrazek Ali et al. “Management of collaterals after Glenn procedure and its impact on patients with a single ventricle: a single-center study” (REC Interv Cardiol. 2024;6:296-304), Table 3 has been modified for clarification. Denominators have been added to explain the percentages. The amended version of Table 3 is:

The Ethical considerations section has been expanded to explicitly state that the required consent to publish images had been obtained. The section now reads:
This study was approved by the research ethics committee of the faculty of medicine of Ain Shams University (FMASU MS 507/2022). Verbal and written informed consent (for study participation, tests, and publication—including photographs—) was obtained from participants aged 18 years and older or from the participant’s guardian in patients aged less than 18 years after the aim of the study was explained to them. Patient images have been adapted as much as possible to preserve privacy while retaining sufficient information to illustrate research. Our research was carried out in accordance with internationally accepted recommendations for clinical investigation (Declaration of Helsinki of the World Medical Association). Possible sex/gender biases have been considered in the preparation of this article.
