Atypical takotsubo cardiomyopathy: dobutamine-precipitated apical ballooning with left ventricular outflow tract obstruction.

Abstract

Takotsubo cardiomyopathy, or transient apical ballooning syndrome, is a recently recognized form of transient left ventricular dysfunction that is presumably caused by stress. Takotsubo cardiomyopathy can clinically resemble an acute coronary syndrome. Reported cases have been preceded by emotional stress or medical illness. Herein, we report a fatal case of takotsubo cardiomyopathy that followed a dobutamine stress test. We believe that the dobutamine infusion led to stress-induced cardiomyopathy with a dynamic left ventricular outflow tract obstruction. To our knowledge, there is only 1 other report of an association between dobutamine infusion and the development of takotsubo cardiomyopathy.
