When the Heart Breaks in the Operating Room (OR): Intraoperative Arrest as a First Sign of Takotsubo Cardiomyopathy.

Cardiac arrest in the operating room is a rare but potentially life-threatening event. This report discusses a case in which a seemingly healthy patient presented for elective total thyroidectomy and experienced intraoperative cardiac arrest requiring cardiopulmonary resuscitation. Takotsubo cardiomyopathy was diagnosed following resuscitation. This case underscores the need for heightened awareness and consideration of Takotsubo cardiomyopathy as a differential diagnosis in cases of perioperative cardiac arrest, particularly when initial findings do not align with typical causes such as myocardial infarction or arrhythmia. Multidisciplinary collaboration, early recognition, and appropriate management are crucial to ensuring patient safety and achieving favorable recovery in such complex clinical scenarios.
