Takotsubo cardiomyopathy caused by XXXX -treated @entity5157 sting anaphylaxis: a case report.

INTRODUCTION: Stress-induced @entity296 (Takotsubo) after @entity5157 stings in @entity1 who have received @entity2661 is rare. Endogenous as well as exogenous administration of @entity2661 is thought to trigger stress-induced @entity296 . CASE PRESENTATION: A 37-year-old healthy white @entity1 was stung by an unknown Hymenoptera that resulted in an anaphylactic reaction. Intravenous @entity1425 (0.9  mg) was administered at a nearby clinic; she was transferred to our emergency room. @entity1455 was diagnosed and mechanical ventilation commenced. Hemodynamic stabilization was not achieved by inotropic support and intra-aortic balloon pump insertion. Initial coronary angiography did not demonstrate any @entity301 while her left ventricular systolic function was severely @entity308 . Peripheral femoral venoarterial extracorporeal membrane oxygenation was inserted as a bridge to recovery assuming possible reversible cause of the @entity1455 . Over the following 48  hours she was extubated and gradually weaned off venoarterial extracorporeal membrane oxygenation and inotropic support. She was discharged with a near normal left ventricular ejection fraction and in 3  weeks she was asymptomatic with normal electrocardiographic and echocardiographic examinations (left ventricular ejection fraction >65  %). CONCLUSIONS: A Hymenoptera sting may be a specific cause of @entity5733 cardiac @entity308 . The presence of @entity1455 and its etiology should prompt aggressive management including extracorporeal membrane oxygenation as a bridge to cardiac functional recovery in such rare scenarios.
