Can elective direct-current cardioversion for atrial fibrillation precipitate takotsubo cardiomyopathy?
Elective direct-current cardioversion for atrial fibrillation may act as a rare trigger for takotsubo cardiomyopathy and subsequent cardiogenic shock.
Case of post-stress cardiogenic shock in takotsubo; hypothesis-generating for triggers and supportive management.
In takotsubo cardiomyopathy, the clinical appearance is that of an acute myocardial infarction in the absence of obstructive coronary artery disease, with apical ballooning of the left ventricle. The condition is usually precipitated by a stressful physical or psychological experience. The mechanism is unknown but is thought to be related to catecholamine excess. We present the case of a 67-year-old woman who experienced cardiogenic shock caused by takotsubo cardiomyopathy, immediately after undergoing elective direct-current cardio-version for atrial fibrillation. After a course complicated by left ventricular failure, cardiogenic shock, and ventricular tachycardia, she made a complete clinical and echocardiographic recovery. In addition to this case, we discuss the possible direct effect of cardioversion in takotsubo cardiomyopathy.

Siegfried et al. (2014) conducted a case report in Atrial fibrillation (n=1). Direct-current (DC) cardioversion was evaluated. Elective direct-current cardioversion for atrial fibrillation precipitated immediate Takotsubo cardiomyopathy and cardiogenic shock in a 67-year-old woman, who subsequently made a complete recovery.
