AbstractTakotsubo cardiomyopathy (TCM) is regarded as an acute and often reversible cardiac syndrome characterised by apical ballooning of the left ventricle that occurs in the absence of coronary artery obstruction and myocarditis. The underlying pathophysiology remains largely unknown, but the most widely accepted theory is catecholamine toxicity.More recently, atypical variants of TCM have been described, and are characterised by the regional wall motion abnormalities that are observed. Mid-ventricular Takotsubo cardiomyopathy (MVTCM) is characterised by hypokinesia/akinesia of the mid left ventricular wall segments with hyperdynamic basal and apical function. This report describes the first documented case of a patient who developed MVTCM after receiving a dose of intravenous adrenaline. This case provides further evidence to support the notion that catecholamine toxicity is implicated in the pathogenesis of TCM.© 2022. The Author(s).
