However, neonatal thyrotoxicosis is a rare but potentially fatal cause of heart failure if left untreated. We present two cases of neonatal thyroid storm manifesting as heart failure and cardiogenic shock, emphasizing the diagnostic challenges, treatment strategies, and transient nature of the disease, which is mediated by maternal thyroid-stimulating hormone receptor antibodies. A literature review is also provided to highlight the clinical approach to this rare but critical condition.<\/jats:p>","DOI":"10.4103\/apc.apc_59_25","type":"journal-article","created":{"date-parts":[[2025,10,7]],"date-time":"2025-10-07T17:02:57Z","timestamp":1759856577000},"page":"276-279","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Thyroid
