Takotsubo Cardiomyopathy Following Traumatic Hand Amputation: A Case Report.

INTRODUCTION: Takotsubo or stress cardiomyopathy is a syndrome of transient left ventricular systolic dysfunction seen in the absence of obstructive coronary artery disease. CASE REPORT: We describe a case of stress cardiomyopathy diagnosed in the emergency department (ED) using point-of-care ultrasound associated with traumatic hand amputation. The patient suffered a near-complete amputation of the right hand while using a circular saw, subsequently complicated by brief cardiac arrest with rapid return of spontaneous circulation. Point-of-care ultrasonography in the ED revealed the classic findings of takotsubo cardiomyopathy, including apical ballooning of the left ventricle and hyperkinesis of the basal walls with a severely reduced ejection fraction. After formalization of the amputation and cardiovascular evaluation, the patient was discharged from the hospital in stable condition 10 days later. CONCLUSION: Emergency physicians should be aware of the possibility of stress cardiomyopathy as a cause for acute decompensation, even in isolated extremity trauma.
