유방확대술 중 발생한 Takotsubo 심근병 1례

Abstract

Purpose: Takotsubo cardiomyopathy is a relatively uncommon type of stress - induced cardiomyopathy characterized by transient left ventricular regional wall motion abnormalities. Emotional and physical stresses play a key role in this type of cardiomyopathy in postmenopausal women. The current hypothesis is that the syndrome represents a form of catecholamine surge due to stress or epinephrine - mediated acute myocardial stunning.Methods: A 44 – year - old woman had suffered premature ventricular contraction following a cardiogenic shock during a breast augmentation surgery under enflurane anesthesia and tumescent solution infiltration, so she was treated with cardiopulmonary resuscitation at a local clinic. Then she was brought to the Emergency Department of the authors’ hospital.Results: The woman’s echocardiogram showed an ejection fraction of 20 – 25 % with associated basal hyperkinesis and left ventricular apical ballooning. The patient was admitted to the ICU and required inotropic support for two weeks. The patient’s condition dramatically improved, and her ejection fraction returned to 70 %.Conclusion: It is believed that there were multiple triggering factors of the onset of Takotsubo cardiomyopathy in the woman’s social and family history, including infiltration of a large volume of the tumescent solution and VPCs induced by enflurane anesthesia without premedication. The importance of careful history - taking, careful pre - operative consultation on psychological suffering especially for breast surgery, premedication before surgery, patient reassurance, and post - operative psychosocial and emotional assistance was again seen in this case.
