Intraoperative Takotsubo Syndrome.

Takotsubo cardiomyopathy is a rare condition that presents a diagnostic challenge due to its close resemblance to acute myocardial ischemia and other cardiac disorders. The excessive production of catecholamines triggers abnormal and severe changes in the myocardium, typically resulting in significant dyskinesia of the left ventricle's apex, reduced ejection fraction, hypotension, and pulmonary edema. Recent reports suggest that potential risk factors may include postmenopausal syndrome and intense, unexpected stress, whether related to life events or medical conditions. Complications such as heart failure, thrombosis, and severe arrhythmias are infrequent and more likely to occur in patients with pre-existing cardiac conditions. We present the case of a 22-year-old woman who developed intraoperative Takotsubo cardiomyopathy during a transsphenoidal resection of a prolactin-secreting pituitary tumor under general anesthesia. Perioperative combination of cabergoline and oxymetazoline induced intraoperative hypertension, pulmonary edema, and Takotsubo stress cardiomyopathy. To our knowledge, this is the first reported case in the literature of intraoperative Takotsubo cardiomyopathy, potentially linked to the specific combination of intraoperative cabergoline and oxymetazoline.
