AbstractTakotsubo syndrome, was described in Japan in 1990, it is a stress cardiomyopathy, predominantly in women, usually postmenopausal. Cardiac hypokinesia occurs, with involvement of multiple coronary territories. In intensive care unit (ICU), it is considered underdiagnosed. Manifestations of severe dengue fever include cardiovascular involvement, mainly arrhythmias and systolic dysfunction. A case of a 72-year-old man is presented, who was hospitalized in ICU for dengue fever, with plateletopenia (15000 cells/mm3) and dehydration. After fluid management the patient reported respiratory discomfort, auscultating crackling rales. A pulmonary ultrasound was made where bilateral B lines were found with B7 pattern compatible with interstitial syndrome and pulmonary edema. Basal hyperkinesia, medial and apical hypokinesia with an image consistent with apical ballooning were observed in the transthoracic echocardiogram. The electrocardiogram showed complete right bundle branch block. Chagas serology was negative and quantitative troponin I was increased. In the context of severe dengue, a Takotsubo syndrome was diagnosed. The patient evolved favorably. After discharge, a normalization of the cardiac function was stated in ultrasound images. The case is of clinical importance due to the low association of these two diseases and the need to screen for cardiac involvement in severe dengue.
