[Takotsubo cardiomyopathy associated with abnormal birth of the coronary arteries].

Abstract

Background: Takotsubo cardiomyopathy (TM) is a form of non-ischemic cardiomyopathy. It is characterized by transient regional systolic dysfunction of the left ventricle that mimics acute myocardial infarction. The main objective of this article is to report the case of a patient with TM associated with abnormal birth of the left coronary trunk.

Clinical case: A 76-year-old woman with typical angina at rest, with an electrocardiogram that showed dynamic changes in the T wave and elevation of biomarkers. Coronary angiography showed epicardial coronary arteries without significant lesions and abnormal birth of the left coronary trunk from the proximal segment of the right coronary artery. The patient progressed favorably, and the transthoracic echocardiogram showed no mobility disorders 3 months after the event.

Conclusions: TM and abnormal birth of the coronary arteries are rare diseases whose simultaneous presentation is extraordinary. The diagnosis of both clinical entities is made by coronary angiography and echocardiogram, and their treatment is similar to that of patients with acute coronary syndrome. Abnormal birth of the left coronary trunk with retroaortic switch reaching the contralateral site has a good clinical prognosis and echocardiographic follow-up should be performed 4 weeks after the onset of the condition.
