Correction to: Nature Reviews Cardiology https://doi.org/10.1038/s41569-023-00940-9, published online 2 November 2023.

In the version of the article initially published, in the “Diagnosis of carditis in an index ARF case” section, the text now reading “pathological mitral and/or aortic regurgitation must be present (as defined in Box 5)” previously cited Box 4. This has now been amended in the HTML and PDF versions of the article.
