JACC: Case Reports is inviting submissions of "complications" for a forthcoming special issue planned for early 2025. Whether it's diagnosis, management, or a miss, we want to know about it. The submissions should be educational so others can avoid the complication in the future. The How We Did it, Multidisciplinary Team Discussion, and Four Corners sections are suggested, but First in Human reports on diagnosing or managing a complication are also welcome. Submissions are due by Tuesday, Oct. 15. Submit here.
