We report a case of Takotsubo syndrome occurring in the recovery phase after a dobutamine stress echocardiogram. Takotsubo syndrome is a widely acknowledged cause of reversible left ventricular systolic dysfunction. It has garnered much attention from the cardiological community since its presentation frequently mimics that of ST-segment elevation myocardial infarction. The exact aetiology remains incompletely defined, although stress is recognized frequently as a precipitating factor. In recent years it has emerged that stress testing, as part of a patient's investigative assessment, can also induce Takotsubo's syndrome. All prior reports of dobutamine-induced Takotsubo's syndrome have described apical ballooning at peak stress. We describe the case of an 85-year-old lady who developed apical ballooning in the recovery period after a dobutamine stress echocardiogram, despite having normal left ventricular wall motion at rest and at peak stress. We believe this to be the first such case reported in the literature. Dobutamine stress testing can precipitate Takotsubo's syndrome not just at peak stress but also during the recovery period. All those performing dobutamine stress tests should be aware of this rare but potentially important complication.
