IMAGES THAT TEACH Myocardial perfusion scintigraphy during chest pain: An atypical presentation of takotsubo cardiomyopathy? a a Maria Marta Maggiotto Sabra, MD, Fernanda Saloma˜o Costa, MD, a a Jader Cunha de Azevedo, PhD, Claudio Tinoco Mesquita, PhD, and Hein J. Verberne, PhD Department of Nuclear Medicine, ProCardiaco Hospital, Rio de Janeiro, Brazil Department of Radiology and Nuclear Medicine, Academic Medical Center, Amsterdam, The Netherlands Received Apr 9, 2018; accepted Apr 9, 2018 doi:10.1007/s12350-018-1286-8 Although Takotsubo cardiomyopathy (TCM) knowledge is increasing, the exact pathophysi- ology remains unclear. TCM represents 1%–2% of all troponin positive acute coronary syndromes, affects predominantly postmenopausal women, and is commonly preceded by exposure to severe physical or emotional stress. Transient wall motion abnormalities mimicking ST-elevation myocardial infarction is expected as well as increase of troponin levels and echocardiography alterations. This case report is about a patient that as far as we know is the ﬁrst case that shows the use of myocardial perfusion imaging in the acute phase of TCM. In general, the TCM Mayo Clinic diagnostic criteria have been very helpful in the clinical setting. In this speciﬁc case, however, the presence of reduced myocardial perfusion in the acute phase combined with increased troponin levels
